▎ 摘　　要

NOVELTY - Preparation of graphene aerogel composite material involves (s1) mixing aerogel and PTFE particles to form a semifinished product (A), (s2) sintering into blocks to form a semifinished product (B), and (s3) cutting into film, calendering, molding, and biaxially stretching. USE - Preparation of graphene aerogel composite material for oil-water separation. ADVANTAGE - The method combines silicon aerogel, graphene aerogel and PTFE particles to improve the strength after oil absorption and increase the volume of oil absorption.
