Synthesis of ‘Reactive’ and Covalent Polymeric Multilayers Coatings with Durable Superoleophobicity and Superoleophilicity Properties under Water

Abstract

Bioinspired underwater super-oil-wettability (superoleophilic/superoleophobic) properties are emerging as a potential avenue for developing smart materials for addresing issues related to healthcare, environment and energy etc. However, the inherent poor durability of the materials that are mostly developed using polymeric hydrogel, metal oxide coatings and electrostatic multilayers, often challenges the application of these wettability properties at practical scenarios. Here, ‘amine-reactive’ polymeric multilayers of nano-complex is developed to fabricate under-water ‘internal’-superoleophobic/superoleophilic coatings with impeccable physical/chemical durability—the super-wetting properties exists beyond the surface of the material, and remained intact even after severe physical damages including erosion of the material, and continuous exposure to artificial-marine environment for more than 80 days. Moreover, this current design allowed to revalidate independently some key hypothesis with direct experimental demonstrations, and provided a basis to develop highly durable super-oil-wettability properties under water. This contemporary study is believed to make a worthwhile contribution to develop a multifunctional materials for widespread practical applications by exploiting these super-oil-wetting properties.
