| 摘 要： | 采用表面原位接枝聚合在纳米CaCO3颗粒表面引入聚甲基丙烯酸甲酯(PMMA)或聚丙烯酸丁酯(PBA),用共混法制备了纳米CaC03/PVC复合材料,研究了不同界面特性时纳米CaCO,/PVC复合材料的力学性能.研究结果表明:通过表面原位接枝聚合反应可以在纳米CaCO3颗粒表面接枝PMMA和PBA;表面接枝聚合改性大大促进了纳米CaCO3粒子在PVC基体中的分散行为,增加了复合材料的拉伸强度以及与聚合物的界面粘接强度,但复合材料的冲击强度有所下降.

| Abstract: | Nano-CaCO3 particles were modified by PMMA or PBA through in-situ surface grafting polymerization and then nano-CaCO3/PVC composites were prepared via a melt blending method.The mechanical properties of nano-CaCO3/PVC composites with different interfacial characteristics were studied.The results showed that in-situ suface grafting polymerization could graft PMMA and PBA onto the surface of nano-CaCO3 particles,which could promote the dispersion behavior of nano-CaCO3 particles in PVC matrix and increase the... |
