摘要
Abstract
The rheological behavior of polyflactic acid) (PLA)/epoxied polyhedral oligomeric silsesquioxanes (EVOS) nanocomposites prepared by melt blending method was investigated by capillary rheometer. The results show that PLA/EVOS nanocomposites are pseudo plastic fluid, and exhibit shear thinning behavior; with the increase of temperature, the non-newtonian index of the composite increases; with the increase of EVOS content, the non-newtonian index of the composite increases at first and then decreases, while both consistency and apparent viscosity decrease at first and then increase; the viscous activation energy of the composite melt is relatively low, which is only 12-35 kJ/mol.关键词
