New polymer alloy could solve energy storage challenge

In the race for lighter, safer and more efficient electronics—from electric vehicles to transcontinental energy grids—one component literally holds the power: the polymer capacitor. Seen in such applications as medical defibrillators, polymer capacitors are responsible for quick bursts of energy and stabilizing power rather than holding large amounts of energy, as opposed to the slower, steadier energy of a battery.

However, current state-of-the-art polymer capacitors cannot survive beyond 212 degrees Fahrenheit (F), which the air around a typical car engine can hit during summer months and an overworked data center can surpass on any given day.

In Nature, a team led by Penn State researchers reported a novel material made of cheap, commercially available plastics that can handle four times the energy of a typical capacitor at temperatures up to 482 F.

The perfect polymer? Plant-based plastic is fully saltwater degradable and leaves behind zero microplastics

In a study published in the Journal of the American Chemical Society, they report a new type of plastic made from plant cellulose, the world’s most abundant organic compound. The new plastic is strong, flexible, and capable of rapid decomposition in natural environments, setting it apart from other plastics marketed as biodegradable.

Microplastics are a global contaminant found in nearly every ecosystem, from the soil and the ocean to the animals and plants that live there. They have even been found in human tissue and the bloodstream, where they likely have adverse effects.

New plastics designed to degrade on demand may help address global waste

Yuwei Gu was hiking through Bear Mountain State Park in New York when inspiration struck. Plastic bottles littered the trail and more floated on a nearby lake. The jarring sight in such a pristine environment made the Rutgers chemist stop in his tracks. Nature makes plenty of long-stranded molecules called polymers, including DNA and RNA, yet those natural polymers eventually break down. Synthetic polymers such as plastics don’t. Why?

“Biology uses polymers everywhere, such as proteins, DNA, RNA and cellulose, yet nature never faces the kind of long-term accumulation problems we see with synthetic plastics,” said Gu, an assistant professor in the Department of Chemistry and Chemical Biology in the Rutgers School of Arts and Sciences.

As he stood in the woods, the answer came to him.

“The difference has to lie in chemistry,” he said.

Polymer beads generate electricity for self-charging devices using simple friction

An international team has discovered a simple and environmentally friendly way to power the next generation of self-charging electronics. The work is published in Nano Energy.

How the technology works

By making tiny plastic spheres move against each other, they generate electricity through friction. Instead of using complex fluoropolymer-based materials, the researchers created ultrathin, structured layers of polymethyl methacrylate (PMMA) spheres using a simple rubbing technique. Typically, producing such ultrathin films requires highly advanced equipment and is both costly and difficult.

The result is thin films only a few micrometers thick—about 10 times thinner than a human hair—that can be inexpensively applied to any hard surface.

A surprising new method finally makes teflon recyclable

New research has identified a straightforward and environmentally friendly way to decompose Teflon, one of the most resilient plastics in use today, and convert it into valuable chemical ingredients.

Scientists at Newcastle University and the University of Birmingham have created a clean, energy-saving process for recycling Teflon (PTFE), which is widely recognized for its role in non-stick cookware and in products that must withstand high temperatures and harsh chemicals.

The team found that discarded Teflon can be broken apart and reused with only sodium metal and mechanical movement by shaking – all at room temperature and without toxic solvents.

An edible fungus could make paper and fabric liquid-proof

As an alternative to single-use plastic wrap and paper cup coatings, researchers in Langmuir report a way to waterproof materials using edible fungus. Along with fibers made from wood, the fungus produced a layer that blocks water, oil and grease absorption. In a proof-of-concept study, the impervious film grew on common materials such as paper, denim, polyester felt and thin wood, revealing its potential to replace plastic coatings with sustainable, natural materials.

A ‘stick-peel-reuse’ adhesive based on lock-and-key chemistry

If you have ever felt the frustration of trying to re-stick a used sticky note, you will understand the challenge of reversible adhesion. Adhesives that can strongly bond to surfaces, be peeled off, and then reused are in high demand for industrial applications.

Unfortunately, the strong bonds formed by conventional adhesives are permanent, such that these adhesives cannot be reused. But now, in a study published in Advanced Materials, researchers at The University of Osaka report the invention of a new polymeric adhesive that can be reused repeatedly.

When two materials come into contact with each other, a region (called an interface) forms between them that contains molecules of both materials. When the interface is wide, it is difficult to pull the materials apart and they are considered to adhere strongly to each other. Adhesion between materials can be activated and deactivated by introducing reversible bonds into this interface.

Strengthening soy for better bioplastics

Soy proteins are used in plant-based natural polymers meant to eventually supplant plastic materials. But to compete with the petrochemical-based products, such polymers need to be stronger and less brittle.

Researchers at Washington University in St. Louis have developed a method to do that, explained in a study published in the journal Polymer Composites. Marcus Foston, a professor of energy, environmental and chemical engineering at the McKelvey School of Engineering, led the research. Foston, who is also director of the Synthetic Biology Manufacturing of Advanced Materials Research Center, studies how to repurpose biomass waste into useful chemicals and materials.

One such example of biomass waste is cellulose, the most abundant natural polymer on Earth. Researchers can yield cellulose nanocrystals from microfibrils of many plant sources and those nanocrystals make good scaffolding for bioplastic materials, but they could be better.

Better, faster, bio-based: Developing functional new plastic alternatives

The plastics industry is in flux, as there is an increasing push to replace petroleum-based materials with sustainable alternatives. But sustainability alone is not enough. Bio-based plastics need to be capable of more.

In the SUBI²MA flagship project, several Fraunhofer institutes are working to accelerate development of new materials that are not only ecofriendly but also functionally superior. They are focusing on three main goals: further development of new bio-based materials, developing new biohybrid materials and digital fast-track development.

Biological components with functional advantages

The bio-based materials arm of the project focuses on Caramide, a new and completely bio-based form of polyamide. Polyamides are high-performance thermoplastics, and Caramide takes the entire class to the next level. It is derived from 3-carene, a terpene that is produced in large quantities as a by-product of cellulose production. Terpenes are natural organic compounds that are found in many parts of plants, such as leaves, flowers and roots, and are also the main components of resins and essential oils.

PET plastic gets antimicrobial boost through plasma treatment and zinc nanoparticles

Polymers are essential in modern food packaging thanks to their low cost, light weight, flexibility, and chemical stability. They provide a crucial barrier to protect food from moisture, oxygen, sunlight, and microorganisms that cause spoilage and health risks. Among them, PET (polyethylene terephthalate) is especially valued for its transparency, stability, and strong mechanical properties.

However, conventional PET and other low-cost polymers have limitations in surface properties such as wettability, adhesion, and resistance to microbial growth. By treating polymers with cold plasma and incorporating nanoparticles (NPs), such as zinc oxide (ZnO), it can improve the polymer’s antimicrobial activity, transport properties, biodegradability, and UV protection.

A team of scientists from the Institute of Physics in Zagreb, in collaboration with partners, developed a simple method to synthesize PET/ZnO composites using commercial PET foils. This study was recently published in Applied Surface Science Advances.
