研究了马来酸酐接枝聚丙烯（MA - g - PP）增容剂对聚丙烯-碳纳米管复合材料力学性能和电性能的影响。以市售聚丙烯均聚物（PP）和多壁碳纳米管（MCNT）为原料，采用熔融复合法制备了PP/MCNT复合材料。研究了马来酸酐接枝水平和负载对材料性能的影响。不添加增容剂的MCNT提高了PP的力学性能，而单独添加两种等级的MA - g - PP则有不利影响。当MA‐g‐PP作为增容剂加入到PP/MCNT复合材料中时，弯曲模量和拉伸模量增加，表明MCNT在PP中的分散水平得到了提高。纳米复合材料的强度随着两种等级MA - g - PP的加入而下降，可能是由于低分子量MA - g - PP存在时聚合物的机械性能恶化。两种等级的MA - g - PP的电阻率都有所提高，其中较高的马来酸酐接枝水平的效果最为显著。扫描电镜分析证实，MA - g - PP纳米复合材料的最佳分散状态为接枝水平最高的MA - g - PP。变异较大。心神。, 2012年。©2012塑料工程师协会
The effect of maleic anhydride grafted polypropylene (MA‐g‐PP) compatibilizer on the mechanical and electrical properties of a polypropylene‐carbon nanotube composite is presented. Commercially available grades of polypropylene homopolymer (PP) and multiwalled CNT (MCNT) were used to prepare composites (PP/MCNT) by melt compounding. The effects of maleic anhydride graft level and loading on material properties were investigated. The addition of MCNT without compatibilizer enhanced the mechanical properties of PP, whereas addition of both grades of MA‐g‐PP alone had a detrimental effect. When MA‐g‐PP was added as a compatiblizer to the PP/MCNT composite, flexural and tensile moduli increased, indicating that enhanced levels of MCNT dispersion within PP had been achieved. Strength of the nanocomposite decreased with the addition of both grades of MA‐g‐PP, possibly due to the deterioration of the mechanical properties of the polymer in the presence of lower molecular weight MA‐g‐PP. Electrical resistivity improved with both grades of MA‐g‐PP, with higher maleic anhydride graft levels having the most significant effect. Scanning electron microscopy analysis confirmed that the optimum state of dispersion was for the nanocomposite prepared with MA‐g‐PP with highest grafting level. POLYM.
