Slippery liquid-infused porous surfaces (SLIPSs) can be formed by impregnating lubricants in with low surface energy. In this study, SLIPSs have been obtained on practically important aluminum a anodic alumina layer containing organic additives. The additive-containing change the slippery even without prior coating of surface. reveal water sliding angle <5° and markedly improved corrosion resistance an acetic acid solution chloride. are situ adsorption additives scratched defects induce coating-type SLIPSs, whereas sustain high after introducing scratch defects. additive refilling lubricant responsible for self-healing resistance. Thus, promising corrosion-resistant surfaces.
