A NIST team has measured the best wood-to-pest ratio for the design of new composites. Tunicates are slimy invasive exotic pests that some people like to eat. Now they may be used to make UV-reflective, flexible construction materials. They have combined derivatives of two surplus materials – wood pulp and dried-up pieces of an invasive exotic pest – to form a new composite material that is flexible, sustainable, nontoxic and UV light-reflective. The material could soon be used in a wide variety of applications, including food packaging, biomedical devices, building construction and the design of cars, trucks and boats.
The key ...
