应用可溶性聚酰亚胺（ＰＩ）Ｌａｎｇｍｕｉｒ－Ｂｌｏｄｇｅｔｔ（ＬＢ）膜沉积在碳钢电极上，研究其在中性及酸性介质中对碳钢的缓蚀作用．结果表明ＰＩＬＢ膜在中性及酸性介质中对碳钢有较好的缓蚀作用，单分子层数目对缓蚀效率有很大的影响．
The soluble polyimide (PI) Langmuir-Blodgett (LB) film was deposited on a carbon steel electrode to study its corrosion inhibition on carbon steel in neutral and acidic media. The results show that the PILB membrane has a good corrosion inhibition effect on carbon steel in neutral and acidic media. The number of monolayers greatly affects the corrosion inhibition efficiency.
