RELATIONSHIP BETWEEN FLUOROCARBON POLIMER COATING AND ITS HYDROPHOBICITY

Fluorocarbon Polymer coating was prepared by RF sputtering. XPS analysis has shown that the surface tension of the coating is close to that PTEE possesses but its molecule structure is different due to fluorine introduced; the percentage of the linking components increases, the F/C decreases, and surface tension of the coating increases with increasing discharge power; therefore its hydrophobicity decreases.
