Bioinspired poly(vinyl alcohol)/zeolite composite coating with multifunctional integration

Underwater superoleophobic coatings have attracted significant research attention for their excellent oil-repellent properties. However, the major challenge for current coatings is poor performance under harsh conditions, leading to limitations in terms of practical application. In this paper, we present a novel bioinspired poly(vinyl alcohol)/zeolite composite coating that can be fabricated through a facile approach. This composite coating shows outstanding underwater superoleophobicity to various oils, as well as good wax-prevention and self-cleaning performance. Furthermore, the excellent mechanical and chemical stabilities of the coating make it suitable for practical applications in harsh environments. This bioinspired multifunctional composite coating has promising prospects in the petroleum industry.
