A kind of antistatic coatings which were applied to nonconductive surfaces were prepared with Polytetrafluoroethylene (PTFE) as matrix, modified carbon black (CB) as conductive filler. Compared to sodium dodecyl sulfate, poly(vinyl pyrrolidone), the TMN-10 modified CB has better wettability, dispersion, stability and re-disperse. When CBcontent is 5 wt.%, the surface resistivity of coating reach to 10Ω*cm, which denotes the coating performance good antistatic behavior. The antistatic coating of 5 wt.% CBcontent is found to exhibit excellent hydrophobicity and high HV hardness. Meanwhile, the low average friction coefficients and wear rate were achieved in antistatic coating of 5 wt.% CBcontent. Furthermore, compared to MXene, reduced graphene oxide, carbon nanotube, the modified CB as conductive material in PTFE antistatic materials could be an useful way not only excellent properties but also large-scale production as well as a reduction in unit cost in antistatic materials.
以聚四氟乙烯（PTFE）为基体、改性炭黑（CB）为导电填料制备了一种应用于非导电表面的抗静电涂层。与十二烷基硫酸钠、聚乙烯吡咯烷酮相比，TMN-10改性炭黑具有更好的润湿性、分散性、稳定性和再分散性。当炭黑含量为5 wt.%时，涂层的表面电阻率达到10Ω·cm，表明该涂层具有良好的抗静电性能。发现炭黑含量为5 wt.%的抗静电涂层具有优异的疏水性和高维氏硬度。同时，炭黑含量为5 wt.%的抗静电涂层具有较低的平均摩擦系数和磨损率。此外，与MXene、还原氧化石墨烯、碳纳米管相比，改性炭黑作为聚四氟乙烯抗静电材料中的导电材料，不仅性能优异，而且可大规模生产并降低抗静电材料的单位成本，是一种可行的方法。
