摘要 高分子材料的绝热特性极大地限制了其作为导热材料在工业中的应用。选用多层石墨烯作为导热填料,并分别与导热填料氧化铝(Al2O3)和碳化硅(SiC)复配,探究导热填料的复配对尼龙6(PA6)复合材料导热性能的影响。加入质量分数为3%石墨烯时,PA6复合材料的热导率为0.548W·m-1·K-1,相比PA6基体提高161%。通过调节石墨烯与Al2O3和SiC复配的比例以及复合填料量,PA6复合材料的热导率可控在0.653~4.307W·m-1·K-1之间,最高是PA6基体的20倍。为拓展石墨烯在导热材料方面的应用及PA6导热材料在工业上应用提供了有价值的实验依据。

Abstract:The thermal insulating properties of polymer greatly restrict the application of polymer as the thermal conductivity materials in industry. Multilayer graphene was chosen as a filler due to its unique thermal transfer property. The effect of alumina oxide (Al2O3) and silicon carbide (SiC) with graphene as hybrid fillers on thermal conductivity of polymers was also explored. The thermal conductivity of the composites enhances 161% with 3%(mass fraction) graphene content compared to pure nylon-6(PA6). The thermal conductivity of PA6 composites is within 0.653-4.307W·m-1·K-1 by adjusting hybrid fillers content and the ratio of graphene with Al2O3 and SiC. The best thermal conductivity is 20 times higher than the pure PA6. It is no doubt that the exploration can provide valuable experimental basis for extending the utilization of graphene as thermal conductivity filler and the application of PA6 thermal conductivity materials in industry.
