Researchers have developed a way to make one type of plastic material more durable and less likely to shed dangerous microplastics.
Found in everything from toys, construction supplies and medical packaging, PVC plastics currently rank third among the most used plastics worldwide. Despite its widespread use, pure PVC is brittle and sensitive to heat, and manufacturers can only utilize it after stabilizing its properties with other chemicals.
Altering PVC molecules in this way allows for them to become more durable and resistant to chemical changes, eventually leading to materials with more robust properties. Today, scientists know that these particles, which have been found to pollute the air, water and our food supply, are harmful both to humans and wildlife. The average person likely ingests between 78,000 and 211,000 of these particles every year.
But using Sevov's method,"You can potentially reuse the material many, many more times before it really begins to fall apart, improving its lifetime and reusability," he said. Other Ohio State co-authors include Jordan L.S. Zackasee, Valmuri Srivardhan, Blaise L. Truesdell and Elizabeth J. Vrana. This work was supported by the Department of Energy's Early Career Research Program.A newly developed plant-based plastic material releases nine times less microplastics than conventional plastic when exposed to sunlight and seawater, a new study has ...
