NOVELTY - A graphene/Schiff base polymer composite material (I) is claimed. USE - Graphene/schiff base polymer composite material used as photoelectric material for detecting sensor, electrochromic display device, thermochromic device and photochromic device (all claimed). DETAILED DESCRIPTION - A graphene/Schiff base polymer composite material having structure of formula (I), is claimed. n=1-100; R1=groups chosen from group of formulae (a)-( j); R2=group of formula (a), (b), (c) or (j), or groups chosen from group of formulae (k)-(p); R'=H or -CH3; m=1-8; R"=(CH2)pCH3;and p=0-8. An INDEPENDENT CLAIM is included for manufacture of the graphite/schiff base polymer composite material by Hummers method. Graphite oxide is converted into graphene using hydrazine hydrate. Poly Schiff's base, graphene and sarcosine are added to anhydrous N,N-dimethyl acetamide. The reaction mixture is ultrasonically treated under nitrogen protection. The temperature is raised to 149-156 degrees C and filtered. The solid material is washed with methanol, and dried under nitrogen protection to obtain graphene/schiff base polymer composite material. The mass ratio of graphene to the base is 0.5-1:1, the mass ratio of sarcosine and the base is 1:3-5, and the volume ratio of the base to N,N-dimethyl acetamide is 1 g:20-50 ml.
