Description
Summary:Superamphiphobic wear-resistance PPS-based coatings were prepared by a simple spraying method with a pore-forming reagent of NH<sub>4</sub>HCO<sub>3</sub> 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 pore-forming,and the porous structures in combination with the CNTs construct the special micro/nano-scale network structures.When the mass fraction of NH<sub>4</sub>HCO<sub>3</sub> is 5%,the contact angles of the coating for water,glycerine and ethylene glycol are 162&#176;,158&#176; and 152&#176;,showing superamphiphobic property.After polished 10000 times by abrasive paper,the coating shows slight friction marks and remains high hydrophobicity,exhibiting excellent wear-resistance.
