Materia: Biodegradable PHB with nanoparticles resolves brittle problem.
Polyhydroxybutyrate (PHB) modified with clay nanoparticles could be the next wave in the biodegradable plastics market. PHB, produced by bacterial action, is a rare example of hydrophobic polymer that is truly biocompatible and biodegradable with high melting temperature and crystallinity. In a study scientists in New York report they have developed a new biodegradable "nanohybrid" plastic that can be engineered to decompose faster than the existing plastics used in everything from soft drink bottles to medical implants.
