▎ 摘　　要

NOVELTY - Preparing super-hydrophobic wood with excellent electrothermal and photothermal effects, comprises (1) placing the wood in a mixed solution of sodium hydroxide and sodium sulfite, heating at 80-100℃ for 6-12 hours, placing in a hydrogen peroxide solution, heating at 80-100℃ for 0.5-2 hours, (2) placing the wood treated in graphene oxide solution, under vacuum condition, performing the load of graphene oxide, blast drying, repeating this process 4-8 times, obtaining the wood saturated with graphene oxide, soaking the wood saturated with graphene oxide in thiourea solution, heating at 60-100℃ for 2-8 hours to reduce graphene oxide and graft sulfhydryl groups, and freeze-drying, and (3) placing the wood in a vinyl-terminated polydimethylsiloxane solution, taking out and curing in an ultraviolet curing oven to obtain an excellent electric heating, and photothermal effect of superhydrophobic wood. USE - The method is useful for preparing super-hydrophobic wood with excellent electro-thermal effect which is used for separating high viscosity oil and in the separation of crude oil and sewage (claimed). ADVANTAGE - The method provides super-hydrophobic wood with excellent electric heating and photo-thermal effect. The wood has three-dimensional porous structure and chemical structure of layer-by-layer bonding. It exhibits stable super- hydrophobic performance and excellent electro-thermally and photothermal effects. It can be quickly heated under the application of voltage or illumination to reduce the viscosity of the crude oil and enhance fluidity and realizes high-efficient and fast separation of crude oil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a super-hydrophobic wood with excellent electro-thermal effect and photo-thermal effect, obtained by the method as mentioned above.
