One biomimetic approach to surface passivation involves a series of surface coatings based on the slick surfaces of carnivorous pitcher plants (Nepenthes). termed slippery liquid-infused porous surfaces (SLIPS). This study introduces a simplified method to produce SLIPS using a polydopamine (PDA) anchor layer. inspired by mussel adhesion. https://www.allfixelectricales.shop/product-category/car-airconditioner-charging-adaptor/
