Mechanical and thermal properties of chitosan filled recycled polyethylene biocomposites

The research was focused to investigate the utilization of chitosan biopolymer on properties of recycled polyethylene (RPE). The effect of chitosan loading of RPE biocomposites on mechanical properties, thermal properties, water absorption and morphology were studied. Chitosan was compounded with...
