NOVELTY - Preparing carbon material single-sided coating fabric using carbon material involves preparing carbon material dispersion with a concentration of 0.35-0.55 wt.%. The carbon materials dispersion is coated on a blank cloth to obtain an interface light hot water-emitting carbon material-single-side coating fabric, where the coating amount of the carbon dispersion liquid of the blank cloth is 26.5-30 uL/cm 2. USE - Method for preparing light hot water evaporation using carbon material single-sided coating fabric for interface photo-thermal water evaporation (claimed). ADVANTAGE - The method is simple, cost-effective, easy to scale production, and has high water-evaporation effect, high energy utilization efficiency, stable structure performance, high cycle stability, and strong large scale use value. The carbon material and material fiber obtains uniform load by optimizing preparation technique, and obtains high energy-utilization efficiency, high structure performance and high photo-thermal conversion efficiency.
