The coatings which contain fluorocarbon and silicone rubber were evaluated in two sea regions.The surface structure of coatings were investigated by FT IR,XPS analyses.This study found that materials of polytetrafluroethylene (PTFE) and rich silicone rubber on coating surface based on the low free energy so that barnacle settling on them was unable to attach permanently and could be removed by moving water.The silicone rubber on coating surface permitted only small amounts of fouling to attach,and very low adhesion of the fouling species was observed.The polyurethane coating has serious fouling.The wettability and surface structure of PTFE,and PTFE powder content in coatings are not effect in antifouling property.
