NOVELTY - Preparation of reduced graphene oxide/polymer dispersion involves carrying out Hummer's method using 30-50 wt.% nitric acid and sulfuric acid at 65-70 degrees C for 12-15 minutes to obtain low graphite oxide solution, dripping amphiphilic polymer solution, mixing completely, ultrasonically processing, stripping, and homogenizing. The reduced graphite oxide solution has carbon dioxide content of 15-20% and total carboxyl carbon content of 5-10%. USE - Preparation of reduced graphene oxide/polymer dispersion used in preparation of reduced graphene oxide composite film (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of reduced graphene oxide composite film, which involves centrifuging obtained dispersion at 2000-4000 rpm for 3-5 minutes, removing lower sediment, centrifuging the supernatant at 10000-12000 rpm for 3-5 minutes, adding deionized water, ultrasonically processing at 50-80 W for 3-5 minutes, centrifuging at 6000-8000 rpm for 10 minutes, removing the supernatant, adding deionized water, ultrasonically processing at 50-80 W for 3-5 minutes, centrifuging at 4000-6000 rpm for 10 minutes, removing the supernatant to obtain 5-10 wt.% large-size suboxide graphene oxide/amphiphilic polymer solution of 65-85%, dripping 3,4-ethylene dioxide thiophene monomer, dripping mixed solution of catalytically oxidizing agent and oxidant, adjusting the pH to 1-2, polymerizing at 10-30 degrees C to obtain reduced graphene oxide/poly(ethylene-3,4-dioxo-thiophene) dispersion in a ratio of 1:0.5-3:1, filtering, drying, adhering using a microporous membrane to obtain reduced graphene oxide/poly (3,4-ethylene dioxide thiophene) film, transferring to a membrane on a transparent flexible substrate to obtain a composite film, dialyzing in 8000-14000 dialysis bag for 24-30 hours, soaking in hydrogen iodide solution at 70-80 degrees C for 10-15 seconds, taking out, washing, and drying.
