Bio-Inspired Underwater Superoleophobic Aramid Nanofiber-Based Aerogel Membranes for Highly Efficient Removal of Emulsified Oils and Organic Dyes

“…Dopamine (DA), known as “bio-glue”, is a mussel-inspired protein that is easily adhere to various material surfaces through polydopamine layer. , However, ascribed to the limited hydrophilicity of DA itself, it is challenging to achieve a superhydrophilic/underwater superoleophobic surface with a single DA modification. In consequence, secondary hydrophilic components, for example, silane coupling agent and inorganic nanoparticles, have been reported to be introduced to the material surface by the codeposition method. − These hydrophilic components mentioned above are expensive and need a sophisticated preparation process. In contrast, chitosan (CS) is a class of natural polysaccharide, rich in amine and hydroxyl groups, exhibits advantages of excellent hydrophilicity, low cost, great biocompatibility, and degradability, and is recognized as a kind of promising surface modification material. − …”
