▎ 摘　　要

NOVELTY - Preparing graphene oxide/titanyl oxalate particles electrorheological fluid material comprises taking polyethylene glycol as dispersant, modifying modified nano particles of graphene oxide/titanyl oxalate by polyethylene glycol, carrying out chemical coprecipitation method, where modified graphene oxide/titanyl oxalate composite nano particles used as dispersed phase, polydimethylsilicone oil as continuous phase, and mixing in a mass ratio 1:1-3:1 to obtain final product. USE - The method is useful for preparing graphene oxide/titanyl oxalate particles electrorheological fluid material (claimed). ADVANTAGE - The method has good dispersibility, high rheological property, good anti-sedimentation performance, not easy to agglomerate and not easy to absorb moisture.
