To address the plastic environmental crisis, Cornell chemists have developed a new polymer with ample strength in a marine setting that is poised to degrade by ultraviolet radiation, according to research published March 30 in the Journal of the American Chemical Society.
“We have created a new plastic that has the mechanical properties required by commercial fishing gear. If it eventually gets lost in the aquatic environment, this material can degrade on a realistic time scale,” said lead researcher Bryce Lipinski, a doctoral candidate in the laboratory of Geoff Coates, the Tisch University Professor in the Department of Chemistry and Chemical Biology, in the College of Arts and Sciences. “This material could reduce persistent plastic accumulation in the environment.”
Commercial fishing contributes to about half of all floating plastic waste that ends up in the oceans, Lipinski said. Fishing nets and ropes are primarily made from three kinds of polymers: isotactic polypropylene, high-density polyethylene, and nylon-6,6, none of which readily degrade.
