A strategy for the corrosion protection of porous materials using conductive polymers and nanocomposites of polymers and nanoparticle is presented. Several conductive polymers, various dopants and different electropolymerization conditions are studied to select the films with the highest corrosion resistance on porous and non-porous materials. It is found that nanocomposite films prepared from two different methods i.e., the co-generation of Au nanoparticles and the dispersion of TiO₂ nanoparticles inside the selected polymer coating give rise to an excellent corrosion resistance. Coated porous samples have the most noble corrosion potentials, the lowest stable passive current densities and the highest polarization resistances.

提出了一种使用导电聚合物以及聚合物和纳米粒子的纳米复合材料对多孔材料进行腐蚀防护的策略。研究了几种导电聚合物，各种掺杂剂和不同的电聚合条件，以选择在多孔和无孔材料上具有最高耐腐蚀性的薄膜。发现由两种不同方法制备的纳米复合膜，即，Au纳米颗粒的共生和TiO ₂纳米颗粒在所选聚合物涂层内的分散，产生了优异的耐腐蚀性。涂层多孔样品具有最高的腐蚀电位，最低的稳定无源电流密度和最高的极化电阻。
