PPC改性的方向以及参考文献
2013-12-16 00:49阅读：
目前国内外对PPC共混复合材料的研究已取得一定的进展，但也存在一些问题：基材PPC的分子量仍需要进一步提高、聚合物和无机粒子与PPC基材的相容性较差、在PPC基质中的分散性不好等。后续的研究还可从以下几个方面继续开展：
（1）以高分子近程结构对其性能影响出发，通过扩链、封端等方法以提高其热稳定性；
（2）从复合材料界面物理和化学性质出发，增加界面区树脂的交联度和结晶度，提高PPC基材和聚合物的界面相容性；
（3）以研究相界面结构和作用机理出发，对天然高分子材料和无机粒子表面改性，增强与PPC基材的化学键作用、减少两相界面局部应力，达到提高PPC复合材料的力学性能和热学性能的目的。
