Abstract

It has been shown that the introduction of a polyaniline dispersion into an alkyd-urethane emulsion leads to a decrease in the average particle size of the modified dispersion. The introduction of undoped polyaniline results in an increase in the stability of the modified dispersion over the entire studied range of contents. It was found that the introduction of doped (up to 2.6 wt %) and undoped polyaniline (up to 3.9 wt %) into coatings brings about an increase in both the initial curing rate and the content of the cross-linked polymer. Electrochemical impedance spectroscopy and polarization studies have shown that the introduction of polyaniline in both doped and undoped forms leads to a decrease in the corrosion current density of steel under the coatings and an increase in their impedance.

聚苯胺改性水性分散材料和涂料的研究

摘要

已经表明，将聚苯胺分散体引入醇酸-氨基甲酸酯乳液会导致改性分散体的平均粒径减小。未掺杂聚苯胺的引入导致改性分散体在整个研究范围内的稳定性增加。发现将掺杂的（高达 2.6 重量%）和未掺杂的聚苯胺（高达 3.9 重量%）引入涂层会导致初始固化速率和交联聚合物含量的增加。电化学阻抗谱和极化研究表明，引入掺杂和未掺杂形式的聚苯胺会导致涂层下钢的腐蚀电流密度降低，并增加其阻抗。
