| 摘 要： | 采用原子转移自由基聚合(ATRP)方法在多壁碳纳米管(MWNT)表面接枝聚丙烯酸丁酯(PBA),制备得到PBA接枝MWNT(MWNT-g-PBA),并以此对聚氯乙烯(PVC)行改性。红外光谱(FTIR)及射电子显微镜(TEM)分析结果表明,采用ATRP法成功地将PBA接枝到MWNT的表面。采用熔融共混法制备了PVC/MWNT-g-PBA复合材料,对其力学性能和耐热性能进行了研究。结果表明,MWNT-g-PBA可以显著提高复合材料的拉伸强度和冲击强度,同时复合材料的耐热性能并未受到较大影响。 |

| Abstract: | Polybutyl acrylate(PBA) was grafted onto the surfaces of multiwalled carbon nanotubes(MWNT) via atom transfer radical polymerization(ATRP),and MWNT-g-PBA was obtained.The MWNT-g-PBA was applied to modify polyvinyl chloride(PVC).Analysis results of FTIR spectra and transmission electron microscopy(TEM) indicate that PBA is grafted onto the surfaces of MWNT successfully.Then PVC/MWNT-g-PBA composites were prepared by melt blending method.The mechanical properties and thermal resistance of the composites were ... |
| Keywords: | polyvinyl chloride multiwalled carbon nanotubes atom transfer radical polymerixation toughening modification |
