导电（抗静电）聚氯乙烯

阐述了影响炭黑填充聚氯乙烯（PVC）导电笥的诸多因素，分析后可知：炭黑在PVC树脂内的分散性是影响其导电性和加工性的关键因素之一；而表面积和结构度可影响炭黑的分散性。当炭黑粒径小于2nm时，其具有很强的吸附能力，需要更多的能量浸润，故分散较困难。同时，由于炭黑吸附在PVC分子链上，降低了PVC的流动性，即降低了加工性能，但提高了其玻璃化温度和力学强度。

Conductive (antistatic) polyvinyl chloride

Factors influencing the conductivity of carbon black filled PVC are discussed briefly.It is found that dispersibility of carbon black inside PVC resin is one of the key influencing factors,and the surface area and structure of carbon black can all influence its dispersibility.When parcile size of carbon black is less than 20 nanometer,its dispersibility is very high and more energy for its imbibition,so it is difficult to disperse.Meanwhile ,the absorption of carbon black on PVC molecular chain can reduce the flowability of PVC,but can increase its glass transition temperature and mechnical property.
