Abstract: At present, physical adsorption is an important technical means for marine oil pollution. Biomass adsorbent materials in the research hotspot of biomass foam have a broad application prospect because of their high porosity and rich 3-dimensional structure, but some biomass foams are complicated to prepare and the preparation process requires toxic organic solvents. In this study, a simple and green sacrificial template method was used. The leaf-PVDF porous sponge material was prepared by letting the PVDF powder melt at 180 ℃ to encapsulate the NaCl particles and leaf powder, and then washing to remove the NaCl template to form a porous structure. The water contact angle of the material in the air is 121°, and the saturated absorption capacity of various oils or organic solvents with a density of less than 0.9 g/cm³ is 350%~540%. The material also has good mechanical properties, maintaining 88% of its original height after 15 compression cycles. When the oil slick on the water surface is recovered by extrusion at room temperature, 4.28 g of pump oil can be recovered within 10 min from 0.35 grams of material, and the water surface becomes clear after recovery, and there is no obvious pump oil residue.
