Composite polymer materials and process for producing the same |
摘要 |
A polymeric composite material contains a biodegradable polymeric material that can be biologically decomposed in soil. More specifically, it contains bacterial cellulose including ribbon-shaped micro-fibrils that can be biologically decomposed by microbes in addition to the biodegradable polymeric material and shows improved physical properties including tensile strength. Such a polymeric composite material can be prepared by a method including steps of causing predetermined microbes cultured in a liquid culture medium to produce bacterial cellulose, collecting and drying the produced bacterial cellulose into a powdery state and mixing the powdery bacterial cellulose and a biodegradable polymeric material to produce a composite material.
