本文采用混酸法和多乙烯多胺(Polyethylenepolyamine,PEPA) 对碳纳米管(Carbon Nanotubes,CNTs) 进行酸化及氨基化改性,再将苯乙烯−马来酸酐共聚物(Styrene Maleic Anhydride copolymer,SMA)接枝在氨基化碳纳米管(CNT-NH
2
) 上,制备了SMA接枝碳纳米管抗静电剂(SMA-g-CNT),并通过将碳纳米管与丙烯腈−丁二烯−苯乙烯共聚物(Acrylonitrile-butadiene-styrene copolymer,ABS)熔融共混制备了原始碳纳米管/ABS(P-CNT/ABS)、氨基化碳纳米管/ABS(CNT-NH

/ABS)和SMA-g-CNT/ABS复合材料。拉曼光谱、傅里叶变换红外光谱分析证实,SMA已成功接枝于碳纳米管表面,且该功能化过程未破坏碳纳米管的本征石墨结构。研究结果表明,在添加质量分数为3%的SMA-g-CNT时,复合材料的表面电阻降至4.2×10

Ω,较同等添加量的P-CNT/ABS复合材料表面电阻降低三个数量级。同时SMA-g-CNT/ABS复合材料的拉伸强度与弯曲强度均有明显提升,冲击强度也有明显的改善。
In this study
carbon nanotubes (CNTs) were acidified and aminated via the mixed acid method and polyethylenepolyamine (PEPA) . Subsequently
styrene-maleic anhydride copolymer (SMA) was grafted onto aminated carbon nanotubes (CNT-NH
2
) to synthesize SMA-grafted carbon nanotube antistatic agents (SMA-g-CNT) . Three types of composites
namely pristine CNT/ABS (P-CNT/ABS)
aminated CNT/ABS (CNT-NH
2
/ABS) and SMA-g-CNT/ABS
were fabrica
ted by melt blending the modified carbon nanotubes with acrylonitrile-butadiene-styrene copolymer (ABS) . Raman spectroscopy and Fourier transform infrared spectroscopy (FTIR) analyses verified that SMA was successfully grafted onto the surface of CNTs
and the intrinsic graphite structure of CNTs remained intact during the functionalization process. The experimental results show that when the mass fraction of SMA-g-CNT was 3%
the surface resistivity of the composite decreased to 4.2×10
8
Ω
which was three orders of magnitude lower than that of P-CNT/ABS with the same filler content. Meanwhile
the tensile strength
flexural strength and impact strength of the SMA-g-CNT/ABS composite were all significantly enhanced.
