Abstract

The invention belongs to the technical field of heat conduction materials, and particularly relates to a single-sided graphene heat dissipation film and a preparation method. The preparation method comprises the following steps: soaking graphene oxide in water, and carrying out ultrasonic stirring; attaching one side of the natural graphite coiled material to a PET double-sided silica gel film with the thickness of 0.01-0.05 mm to prepare a natural graphite gum coiled material for later use; and coating the other surface of the natural graphite coiled material with the obtained graphene oxidesolution, and continuously drying so that the thickness of the dried surface of the graphene oxide solution is 0.02-0.05 mm, and the graphene heat dissipation film coiled material is prepared. The method is simple in production process and convenient to operate, and the obtained product is stable in quality, good in effect and suitable for application and popularization. The single-sided grapheneheat dissipation film is suitable for being used in high heat dissipation of various electronic products, the running speed of the electronic products can be increased, the comfort of users can be improved, and the service life of the products is prolonged.

Description

technical field [0001] The invention belongs to the technical field of heat-conducting materials, and in particular relates to a single-sided graphene heat-dissipating film and a preparation method thereof. Background technique [0002] With the expansion and popularization of electronic and electrical equipment applications, the performance and structure requirements of electronic equipment are becoming more and more stringent, including higher processing speed, higher processing frequency, smaller volume, lighter weight, and more high power. The upgrading of electronic equipment brings great convenience and excellent experience to people's life, but also brings more heat generation, more serious electromagnetic wave pollution and other problems. [0003] At present, domestic and international heat dissipation products mainly use artificial graphite, natural graphite and metal materials for heat dissipation. Artificial graphite coil is one of the main products in the curr...
