Study of PP/nano-TiO₂ Composites on Plastic Mechanism after Microwave Irradiation

Abstract:

Prepared PP/ nano-TiO2 composites by MeltExtrusion,according to compare the changing of their elongation at break、yield strength and tensile strength before and after microwave irradiation, using SEM、TEM and FIR to observe the change，then could obtain that on one side microwave irradiation could vibration the group of molecular chain, friction produce energy makes composites degradation, on the other side, it improves the distribution of inorganic particle in matrix, two phase compatibility and interface combination, from that ,we get the plastic mechanism of microwave irradiation.
