A novel sandwich-structured composite from biopolymers for building envelope applications

Iranpolymer/Baspar A new sandwich-structured composite has been developed from the surface layers of polyhydroxyalkanoate (PHA) and the interlayer of polylactic acid and cellulose microfibers. The biodegradable cellulose microfibers can be modified chemically with a sol-gel process to improve the compatibility between natural reinforcement and the…
