以硝化棉作为原料，选择碳系导电填料，通过液相共混复合法，制备了抗静电硝化棉薄膜。用高阻计和静电感度测试仪、电子万能试验机及场发射扫描电子显微镜分别表征了抗静电硝化棉薄膜的抗静电性能、力学性能以及微观形貌。结果表明，当添加1％的碳系导电填料时，抗静电硝化棉薄膜的表面电阻率和体积电阻率分别为：2．2×109Ω和7．5×109Ω· m，相比纯硝化棉，分别降低了6个数量级和3个数量级。其静电火花感度为2．31 J，相比纯硝化棉，增大了14％，显示最佳抗静电性能。力学性能参数有所提高，说明导电填料的加入，不会削弱硝化棉本身的力学性能。制品内部形成的均匀导电网络会使静电荷消散。

A kind of antistatic nitrocellulose ( NC) membrane was successfully prepared via the liquid phase mixing complex meth-od using NC as raw materials and selecting carbon series conductive filler to NC.The antistatic performance, mechanical property and microstructure of antistatic NC membrane were characterized by high resistance meter, static sensitivity tester, electronic uni-versal testing machine and field emission scanning electron microscope, respectively.The results show that when 1.0% conduc-tive filler is added, the surface resistivity and volume resistivity of the antistatic NC membrane are 2.2 ×109Ωand 7.5 ×109Ω· m. respectively.Compared with unmodified NC, the surface resistivity and volume resistivity of the antistatic NC membrane are re-duced by 6 orders of magnitude and 3 orders of magnitude, respectively.The electrostatic spark sensitivity of the antistatic NC membrane is 2.31 J.Compared with unmodified NC the electrostatic spark sensitivity of the antistatic NC membrane is increased by 14%, revealing that the antistatic NC membrane has better antistatic performance.The mechanical property parameters of the antistatic NC membrane are improved, showing that the addition of conductive filler does not degrade the mechanical property of NC .The formation of interlaced conductive networks in the products is conduciue to the electrostatic charge dissipate.
