摘要

摘要: 采用竖式炉流动法制备的碳纳米管经液相阳极氧化表面处理后增强ABS热塑性工程塑料。复合材料的力学性能研究显示:碳纳米管的加入有效提高了复合材料的拉伸性能,但材料的耐冲击性能下降。当碳纳米管含量为12 wt%时,复合材料的拉伸强度由45.00 MPa提高到69.96 MPa,杨氏模量由0.75 GPa提高到1.93 GPa。对碳纳米管/ABS复合材料的反射系数测定表明:复合材料在一定频率范围内有雷达波吸收性能。

Abstract: Carbon nanotubes (CNTs) were prepared by the catalytic floating method in a vertical furnace. They were compounded with acrylonitrile-butadiene-styrene (ABS) after surface treatment. The tensile strength and modulus of the CNTs/ABS composite had increased greatly, but the impact strength had decreased for addition of CNTs. The tensile strength increased from 45.00 MPa to 69.96 MPa, modulus from 0.75 GPa to 1.93 GPa when the content of CNTs in composite increased from 0 wt% to 12 wt%. The radar absorbing property of the CNTs/ABS composite was also studied, and it was found that the composite material exhibited the radar absorbing property in some band range.
