利用电化学阻抗谱法考察了普通涂层、纳米复合涂层 和憎水纳米复合涂层的防腐性能.结果表明，纳米复合涂层的防腐性能明显高于普通涂层， 而经过氟表面活性剂改性的表面憎水的纳米复合涂层的防腐性能更好.
Corrosion perfomance of three kind of coatings,i.e. the PPS based coatings filled with microsized-(normal coating) or nanosized pigm e nts(nanocomposite) and the later one plus a post treatment with a surfactant of fluorine(hydrophobic nanocomposite coating),was investigated by means of electro chemic al impedance spectroscopy(EIS) mesearement.The results show that the nanocomposi te coating showed better corrosion resistance than the normal ones.However,the h ydrophobic nanocomposite coatings showed the best corrosion resistance,which may be owed to the beneficial effect induced by the treatment with surfactant of fl uorine.
