摘要：

Underwater superoleophobic coatings exhibit promising prospects in the field of oil contamination resis-tance. However, their poor durability, stemming from the fragile structures and unstable hydrophilicity, greatly restricted their development. In this report, we proposed a novel strategy of combination water -induced phase separation and biomineralization to prepare the robust underwater superoleophobic epoxy resin-calcium alginate (EP-CA) coating by utilizing a surfactant-free emulsion of epoxy resin/ -sodium alginate (EP/SA). The EP-CA coating not only exhibited excellent adhesion to various substrates, but also had remarkable resistance to the physical/chemical attacks such as abrasion, acid, alkali and salt. It could also protect the substrate (e.g., PET substrate) from the damage of organic solution and the foul-ing of crude oil. This report provides a new perspective to fabricate robust superhydrophilic coating with a facile way. (c) 2023 Elsevier Inc. All rights reserved.
