Abstract:
The present invention fabricates a hydrophobic and oleophobic polymer fabric through two stages of modification using atmospheric plasmas. The modified fabric has a rough surface and a fluorocarbon functional group having the lowest surface free energy. The fabric has a grafted fluorocarbon monomer layer to enhance the graft efficiency of the fluorocarbon functional groups and its wash fastness. The atmospheric plasmas can be mass produced and less expensively. Hence, the present invention can rapidly modify surfaces of polymeric materials with low cost and good environment protection.
