应用电化学法从苯酚水溶液中制取聚苯酚膜并对其进行了耐蚀性研究。以304不锈钢为电极，Na₂SO₄为电解质，电化学法处理苯酚水溶液，阳极不锈钢表面覆有膜状反应产物，红外分析证实该产物中含有聚苯酚。采用点蚀电位法评判不同反应条件下形成的聚苯酚膜的耐蚀性能，结果表明在0.1mol/L苯酚与0.1mol/L硫酸钠的混合水溶液中、2.4V槽电压、常温、反应1h后形成的聚苯酚膜的耐蚀性能最好。采用扫描电镜分析不同反应时间下形成的聚苯酚膜，结果表明聚苯酚膜以层状方式生长，形成的片层叠加结构有利于提高聚苯酚膜的耐蚀性。

Poly(phenol) films have been prepared from phenol solution by electro-polymerization and their corrosion resistance studied. With a 304 stainless steel working electrode and Na₂SO₄as the supporting electrolyte, phenol from the aqueous solution was polymerized on a stainless steel anode to give a film, which was shown to contain poly(phenol) by infrared spectroscopy. The corrosion resistance of the films in 3.5% sodium chloride solution was characterized by measuring their pitting potential. The film having the best corrosion resistance was formed in 0.1mol/L phenol and 0.1mol/L Na₂SO₄mixed solution after one hour at room temperature, with a cell voltage of 2.4V. Scanning electron microscopy was used to analyze the poly(phenol) films formed after different electro-polymerization times. It was concluded that the poly-phenol film grew along the sheet and that the stacked layer structure of the film helped to improve its corrosion resistance. Electro-polymerization of phenol in aqueous solution may provide a new way of wastewater treatment.
