▎ 摘　　要

NOVELTY - The method involves dissolving graphene oxide into deionized water. Graphene oxide solution is prepared by carrying out ultrasonic process. The graphene oxide solution is added with three-dimensional porous polyaniline to obtain stirred solution. Tin-II chloride solution and hydriodic acid solution are added with the stirred solution. The stirred solution is transferred to a reaction kettle based on the ultrasonic process. The stirred solution is heated at specific temperature and cooled to room temperature. Mass ratio of tin and oxidized graphite alkene is 0.1-0.2: 1. USE - Industrial polyaniline/graphene/tin composite material preparation method. ADVANTAGE - The method enables simplifying composite material preparation process with environment-friendly and reliable usage and forming regular space structure of the composite material with better dispersibility, high energy density and power density and better circulation performance. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view illustrating an industrial polyaniline/graphene/tin composite material.
