Abstract

Oil pollution damages the water, air, and soil, thus posing a threat to human health and biodiversity. The scientific and effective solution to oil pollution and the separation of oil and water has become an urgent problem to be solved. In this paper, a super-wetting oil-water separation membrane with micro square hole-nanowire composite structure and its laser composite preparation method are proposed. The influence of the scanning times of the picosecond UV laser on the evolution of pore formation was studied. The morphologies of laser-fabricated array holes without cleaning, alcohol cleaning and hydrochloric acid cleaning were analyzed. It was found that the covered particles could only be removed by cleaning with hydrochloric acid. The changes in the oxygen content of the inner wall and edge of the hole were analyzed by EDS, and it was found that the oxygen content could be greatly reduced only after cleaning with hydrochloric acid. The characterization of dynamic wettability indicated that the prepared membranes had excellent superhydrophilicity. The oilwater separation test verifies that oil and water can be effectively separated, which has a certain enlightening effect on the preparation of oil-water separation membrane by laser.
