What to know about Novel plastic turns into a gas when heated—then reforms once cooled

Researchers at the University of Surrey have developed a novel polymer that can be depolymerized into a gas at 90 degrees Celsius and then reform into its original state upon cooling. The study, published in Macromolecules, demonstrates potential applications in waterproof coatings and material purification as a proof of concept for circular materials.

What happened

Novel plastic turns into a gas when heated—then reforms once cooled Sadie Harley Scientific Editor Robert Egan Senior Editor In a study published in Macromolecules, researchers introduce a novel polymer that could simplify how materials are applied, removed…

Why it matters

Conventional plastics such as polyethylene, used in everyday products such as plastic bags, food packaging and shampoo bottles, are persistent and not suitable for chemical recycling.

Common ground

While other chemically recyclable polymers have been developed, they typically require much higher temperatures of around 150–200 degrees Celsius to break down, and the recovered material often needs additional chemical processing before it can be turned back…
