摘要:

制备了一种含萘聚芳醚酮(Nap-PAEK), 以其作为表面修饰剂对多壁碳纳米管填料进行了表面包覆. 采用包覆后的多壁碳纳米管与聚醚醚酮(PEEK)进行物理共混得到一系列聚醚醚酮/碳纳米管复合材料, 并研究其力学性能和热性能. 研究结果表明, 由于含萘聚芳醚酮与多壁碳纳米管之间存在较强的π-π相互作用, 因此较好地改善了多壁碳纳米管在溶液和树脂基体中的分散性. 修饰后的多壁碳纳米管在N-甲基吡咯烷酮(NMP)溶液中的分散量较修饰前提升了10倍, 而采用修饰后的多壁碳纳米管制备的聚醚醚酮复合材料, 在碳纳米管添加量仅为2%(质量分数)时, 复合材料较纯PEEK树脂的拉伸强度和断裂伸长率分别提高了14.5%和116.7%, 实现了对聚醚醚酮树脂的同步增强增韧效果, 而且复合材料的耐热性能也有较大提升.

Abstract:

A kind of poly(aryl ether ketone) containing naphthalene(Nap-PAEK) was prepared and coated on the surface of multi walled carbon nanotube(MWCNTs) fillers as surface modifier. A series of PEEK/MWCNTs composites was prepared by physical blending of the MWCNTs coated with Nap-PAEK and poly(ether ether ketone)(PEEK) resin, and the thermal and mechanical properties of the composites were also investigated. The results show that Nap-PAEK can improve the dispersion of MWCNTs in N-methyl-2-pyrrolidone(NMP) solution and PEEK matrix effectively due to the strong π-π interaction between Nap-PAEK and MWCNTs. After surface modified by Nap-PAEK, the dispersion capacity of MWCNTs in NMP increased about 10 times. With the addition of only 2%(mass fraction) WMCNTs, PEEK/Nap-PAEK-MWCNTs composite shows the tensile strength increased by 14.5% and the elongation increased by 116.7% compared to those of pure PEEK, realizing the simultaneous reinforcing and toughening of PEEK resin. After the addition of modified MWCNTs, the thermal stability of PEEK was also improved.
