Abstract: Disclosed are a lithium salt/polyacrylonitrile/thermosetting resin composite material and a preparation method therefor. 100 parts of polyacrylonitrile and 550-1100 parts of N,N-dimethyl formamide by mass are stirred at a temperature of 25° C.-80° C., and a uniform and transparent polyacrylonitrile solution is obtained; further, 8-36 parts of a lithium salt is added; and the mixture is stirred until a uniform and transparent lithium salt/polyacrylonitrile solution is obtained. A heat-curable resin is added to the lithium salt/polyacrylonitrile solution, and is uniformly mixed. The obtained composite solution is made into a film, and a lithium salt/polyacrylonitrile/thermosetting resin composite material is then obtained after curing and post-treatment. The lithium salt/polyacrylonitrile/thermosetting resin composite material has the advantages of a high dielectric constant and a good flexibility and transparency, and the preparation method of the composite material has the characteristics of a simple operation process, low manufacturing cost and wide applicability.
