Thermal and physico-mechanical properties of polyhydroxyalkanoates of Rhodococcus erythropolis Au-1, Pseudomonas sp. PS-17, Azotobacter vinelandii N-15 and polyhydroxybutyrate/polylactide (PHB/PLA) blends were investigated. The addition 5 wt% PLA improved PHB properties, such as thermal resistance and stiffness. However, higher PLA content led to a decrease in thermal stability, while increasing elongation...
Silica having amine functional groups (A-SiO2) obtained by the sol-gel process was used to improve compatibility of polyamide 11 and poly(phenylene oxide) (PA11/PPO 80/20) blend via reactive extrusion in a co-rotating twin screw extruder. Amine functional groups of A-SiO2 can react with the carboxyl groups of PA11 to form graft copolymer with PA11 which can efficiently control the phase morphology...
