在聚4-甲基1-戊烯(TPX)中分别加入多壁碳纳米管(MWNT)、羟基化多壁碳纳米管(MWNT-OH)、羧基化多壁碳纳米管(MWNT-COOH),制备了TPX/碳纳米管(CNTs)复合材料.研究了CNTs对复合材料结晶性能与力学性能的影响.结果表明:加入CNTs对TPX的熔点与晶体结构没有影响,但复合材料的结晶度有所降低;加入CNTs可提高复合材料的弹性模量,与MWNT-OH相比,MWNT更能提高复合材料的弹性模量;随着MWNT-COOH含量的增加,TPX/MWNT-COOH复合材料的弹性模量也得到很大提高,当w(MWNT-COOH)为5.0%时,复合材料的弹性模量达257?MPa.

A series of poly(4-methyl-1-pentene)(TPX)/carbon nanotubes(CNTs)nanocomposites were prepared by adding mumti-wall carbon nanotubes(MWCNT),hydroxylated mumti-wall carbon nanotubes(MWCNT-OH)and carboxylic mumti-wall carbon nanotubes(MWCNT-COOH),respectively. The effects of CNTs on crystallization and mechanical properties of poly(4-methyl-1-pentene)were studied. The results show that adding CNTs has no effect on the melting temperature and crystal structure of TPX,but the crystallinity of the nanocomposite is decreased. The addition of CNTs can improve the elastic modulus of the nanocomposite. MWNT is better than MWNT-OH on increasing the elastic modulus of the nanocomposite. The elastic modulus of TPX/MWNT-COOH nanocomposite is greatly increased with the augment of MWNT-COOH content. The elastic modulus of TPX/MWNT-COOH nanocomposite reaches 257 MPa when the mass fraction of MWNT-COOH is 5.0%.
