Functional polyhydroxybutyrate/antimicrobial terpenoid systems with controlled degradability

Popis výsledku v původním jazyce

Widespread environmental concerns associated with petroleum-based plastics led to the increased interest in biodegradable polymer systems in recent years. Polyhydroxy butyrate (PHB), known for its biocompatibility and biodegradability, represents a suitable alternative throughout many industries. However, its rapid degradation may limit some of its applications, e.g. in agricultural mulching films that should be completely biodegradable in the soil, but have to retain their properties during their limited service lives. Natural antimicrobial monoterpenes were blended with PHB polymer to study the effect on the on the degradability and to control the rate of biodegradation of these materials in soil. The results indicated that thymol, eucalyptol, and limonene were the most promising additives for slowing down the biodegradation of the materials in the soil, while the effect of the other tested compounds seemed marginal. These bio-based additives thus offer a promising strategy to control the PHB degradability process.
