摘要:
通过哈普混炼式转矩流变仪熔融共混制备了聚丙烯/量子能粉(Polypropylene/Quantum Energy powder, PP/QE)纳米复合材料,利用差示扫描量热仪、热台偏光显微镜和热重分析仪研究了量子能粉作为改性剂对PP结晶性能及热性能的影响,并使用Dobreva法定量分析了PP/QE纳米复合材料非等温结晶过程的成核活性。结果表明:QE粉对PP结晶起促进异相成核作用,使结晶速度加快、球晶数目增多尺寸变小;QE粉的添加量为3 wt%,试样的成核活性最高,PP的结晶温度和结晶度较PP空白试样分别提高了8.9 ℃和6.49%,熔点小幅增高,过冷度减小,结晶能力增强; PP/5%QE复合材料的热稳定性大幅度提高,共混物的初始分解温度从374.54 ℃提高到了422.88 ℃。
