    • A practical and environmentally-friendly method, i.e. the high temperature-mechanical mixing by using an internal mixing device and a two-roll open milling device is used to produce the carbon blacks-free electrically conductive sulfur-vulcanised rubber blends of solid poly(butadiene-co-acrylonitrile) and solid sulfonic acid doped polyaniline. The addition of sulfur vulcanisation system does not affect the electrical properties of the vulcanised blends. All vulcanised blends prepared by using this method show useful electrical conductivities up to the order of 10−2 S/cm, good tensile strengths up to 18.0 MPa and colourable with the addition of a whitening agent. As a result, they have good potential to be used for manufacturing any antistatic products, electrostatic discharge or dissipative products and electromagnetic or radio frequency interferences shielding products.
    • 使用实用和环境友好的方法,即通过使用内部混合装置和双辊开放铣削装置的高温 - 机械混合来制造固体聚(丁二烯)的无炭黑导电硫硫化橡胶共混物 - 丙烯腈)和固体磺酸掺杂的聚苯胺。 加硫硫化体系不影响硫化混合物的电性能。 通过使用该方法制备的所有硫化共混物显示高达10-2S / cm的有用的电导率,高达18.0MPa的良好的拉伸强度和加入增白剂的可塑性。 因此,它们具有很好的潜力用于制造任何抗静电产品,静电放电或耗散产品以及电磁或射频干扰屏蔽产品。
