摘要
制备了多壁碳纳米管(MWCNTs)/甲苯二异氰酸酯(TDI)反应生成物和环氧树脂(Ep)的复合物,并对其进行了红外表征及形态学研究。扫描电镜(SEM)显示碳纳米管很好地分散在环氧树脂中。X射线衍射仪(XRD)测试结果表明复合材料为半结晶态。复合材料的体积电阻率由纯环氧树脂的1016降低到108,导热系数提高到纯环氧树脂的近1倍。
Multiwalled carbon nanotube (MWCNT)/epoxy composites are prepared, and the characteristics and morphological properties are studied. Scanning electron microscopy microphotographs show that MWCNTs are dispersed on the nanoscale in the epoxy resin. X-ray diffraction (XRD) test results showed that the composite materials for the semi-crystalline state. The bulk resistivity decreases from 7.25 × 10^16Ω× cm for neat epoxy to 3.2×10^8Ω cm for 11wt% MWCNT/epoxy.
