▎ 摘　　要

NOVELTY - An intelligent energy-saving graphene oxide composite paper comprises graphene oxide (balance) and organic phase change material (1-85 wt.%). The organic phase change material is a fatty alcohol, a fatty acid or paraffin. USE - An intelligent energy-saving graphene oxide composite paper. ADVANTAGE - The paper can prevents leakage of organic phase change material, has improved thermal conductivity and simple operation, is cheap, can be applied for industrial production, and can meet thermal interface material component requirement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite paper comprising: (A) mixing (g) potassium persulfate (1) and phosphorus pentoxide (1), adding 98% concentrated sulfuric acid, adding graphite (0.6-1 g) to the obtained solution (200 ml), and heating the mixture at 85-90 degrees C for 4.5 hours; (B) adding deionized water (200 ml), stirring, filtering, washing the filter cake, and vacuum drying at 60 degrees C; (C) mixing 98% concentrated sulfuric acid (20-25 ml) and potassium permanganate (1 g), adding dried product, heating at 30-40 degrees C for 2 hours, adding deionized water (20 ml), and heating the mixture at 95 degrees C for 0.5 hours; (D) adding hydrogen peroxide solution (30 mass%), centrifuging, filtering, washing the filter cake, and vacuum drying at 30-40 degrees C; and (E) mixing hydrochloric acid and deionized water to obtain a solution having a concentration of 10 mass%, adding dried product, subjecting mixture to ultrasonic treatment for 30-60 minutes, filtering, and vacuum drying obtained filter cake at 30-40 degrees C for 30 minutes.
