以NH4HCO3为造孔剂，碳纳米管(CNTs)为纳米级纤维填料，采用简单的喷涂工艺制备出超双疏耐磨聚苯硫醚(PPS)基涂层。采用扫描电镜(SEM)、接触角测量仪分析涂层的表面形貌和疏水、疏油性能。采用定载砂纸打磨法测试双疏涂层的耐磨损性能。结果表明:造孔后的涂层表面粗糙，表面的多孔结构和CNTs构成了特殊的微纳二元复合网络结构。当NH4HCO3的含量为5％(质量分数)时，涂层实现超疏水和超疏油，对水、甘油和乙二醇的接触角分别为162°，158°和152°。用砂纸反复打磨10000次后，涂层表面轻微磨损，仍保持了高疏水效果，具有良好的耐磨性能。
Preparation and Properties of Superamphiphobic Wear-resistance PPS-based Coating
Superamphiphobic wear-resistance PPS-based coatings were prepared by a simple spraying method with a pore-forming reagent of NH4 HCOa and nano-filler of carbon nanotubes (CNTs).The surface morphology and the hydrophobicity,oleophobicity of the coating were analyzed by scanning electron microscope (SEM) and contact angle meter.The wear-resistance of the coating was verified by sanding method with given load.The results indicate that a rough surface is obtained after poreforming,and the porous structures in combination with the CNTs construct the special micro/nanoscale network structures.When the mass fraction of NH4 HCO3 is 5％0,the contact angles of the coating for water,glycerine and ethylene glycol are 162°,158° and 152°,showing superamphiphobic property.After polished 10000 times by abrasive paper,the coating shows slight friction marks and remains high hydrophobicity,exhibiting excellent wear-resistance.
