Nanocomposites provide significantly increased modulus, thermal, and electrical properties when compared to traditional reinforced composites. Present work was undertaken to study the microstructure, thermal, and electrical properties of carbon nanostructured reinforced polymer matrix composites. Composites were made with carbon nanofibers and nanotubes (produced by CVD method) as reinforcement with thermoplastic polymers as matrices. The amount of nanoreinforcements was varied between 1 to 5 wt% in different matrices. The problems associated with dispersion of reinforcing materials have been studied. Dispersion of nanofillers in thermoplastics, microstructures, and thermal stability of the reinforced thermoplastics have been studied using SEM, DSC, and TGA. Experimental results show that small amount of carbon nanofillers present in thermoplastic matrix systems enhance the thermal, mechanical, and electrical properties of the composites.
与传统增强复合材料相比,纳米复合材料的模量、热性能和电性能显著提高。开展当前工作以研究碳纳米结构增强聚合物基复合材料的微观结构、热性能和电性能。复合材料以碳纳米纤维和纳米管(通过化学气相沉积法生产)作为增强材料,热塑性聚合物作为基体。在不同基体中,纳米增强材料的用量在1至5 wt%之间变化。已研究了与增强材料分散相关的问题。使用扫描电子显微镜(SEM)、差示扫描量热法(DSC)和热重分析法(TGA)研究了纳米填料在热塑性塑料中的分散情况、增强热塑性塑料的微观结构和热稳定性。实验结果表明,热塑性基体系统中存在的少量碳纳米填料可提高复合材料的热性能、机械性能和电性能。
