▎ 摘　　要

NOVELTY - Preparing irradiated modified carbon-based photo-thermal gel comprises stirring the carbon material and modifier in the solvent uniformly to obtain stable mixed dispersion, irradiating the mixed dispersing liquid with high energy ray, coating the irradiated dispersion liquid on the surface of the fabric, soaking the coated fabric into the cross-linking agent solution for crosslinking and fixing, then washing the surface after freezing treatment, and drying. USE - Preparation method of irradiation modified carbon-based photo-thermal gel used in solar energy driving interface water evaporation system. Can also be used in water purifying, sea water desalting and industrial waste water zero discharge treatment field. ADVANTAGE - The method has short process flow, mild condition, simple device, simple operation, low cost, suitable for mass production, and realizes the application prospect of technical industrial transformation. The method provides irradiation modified carbon-based photo-thermal cloth gel with high mechanical strength and stable photothermal performance. The modified carbon material does not need purification process, after the reaction material is directly used as the subsequent coating of the material liquid, simplifies the process steps and experimental device.
