PP/LMPM复合材料中PP的结晶行为
CRYSTALLIZATION BEHAVIOR OF POLYPROPYLENE IN PP/LMPM COMPOSITES
摘要
Abstract
Abstract The kinetics of nonisothermal and isothermal crystallization of polypropylene melt in polypropylene/low melting point metal( PP/PM) composites was investigated by DSC.PM is shown to be the nucleating agent of PP crystallization,and DBTL can increase the speed of PP crystallization.The higher the rotation speed in mixing process, the more the crystal nuclei. The crystallite dimension of PP decreases with the increase of volume fraction of PM, the increase of rotation speed in mixing process and the increase of volume fraction of DBTL. But homogeneous nuclei in PP/PM composites always exist and decrease to a limiting value with the increase of PM and DBTL.关键词
