在Haake扭矩流变仪上成功制备了抗静电聚氯乙烯/季铵盐基离子导电丙烯酸酯共聚物（PVC/QASI）复合材料。当QASI含量达到20 phr时，PVC/QASI复合材料的表面电阻率可降低到10(7)Omega sq（-1）个数量级。复合材料的表面电阻率对相对湿度（RH）略敏感，在相对湿度为12%时表现出良好的抗静电能力。力学性能测试、差示扫描量热法（DSC）和扫描电镜（SEM）也分别研究了PVC/QASI复合材料的拉伸强度、断裂伸长率、热性能和形貌。(C) 2013 Elsevier B.V.版权所有
Antistatic poly(vinyl chloride)/quaternary ammonium salt based ion-conductive acrylate copolymer (PVC/QASI) composites were successfully prepared in a Haake torque rheometer. The surface resistivity of the PVC/QASI composites could be reduced to 10(7) Omega sq(-1) order of magnitude when the QASI content reached 20 phr (parts per hundreds of resin). The surface resistivity of the composites was slightly sensitive to the relative humidity (RH), showing a good antistatic ability under an RH of 12%. Mechanical properties tests, differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) were also used to investigate the tensile strength, elongation at break, thermal properties, and morphology of the PVC/QASI composites, respectively.
