为了进一步提高聚丙烯的力学性能,以马来酸酐接枝聚丙烯(PP-g-MAH)为聚丙烯/二氧化硅(PP/SiO2)纳米复合材料的界面相容剂,研究了PP-g-MAH添加量对PP/SiO2的力学性能、微观形态以及结晶行为的影响,并研究了其增容机理.研究表明:PP-g-MAH的加入使纳米PP/SiO2纳米复合材料的力学性能得以全面提高,使纳米二氧化硅与聚丙烯的界面粘结得到改善,并且,由于PP-g-MAH导致复合材料的界面强度提高和界面层厚度增加,使KH-570与PP-g-MAH并用的PP/PP-g-MAH/纳米SiO2复合材料比单用KH-570的PP/SiO2纳米复合材料的改性效果更加明显;PP-g-MAH对PP的结晶过程具有较明显的成核作用,使改性PP的结晶温度提高.
