AI Technical Summary
Existing graphene heat dissipation films have weak longitudinal heat dissipation capacity and low heat capacity, and traditional preparation methods may cause environmental pollution and damage to graphene sheets.
Graphene phase change composite heat dissipation film was prepared by roller pressing and hot pressing. Graphene nanosheets, phase change materials and binders were mixed by ball milling, avoiding the use of organic solvents and high-temperature heating, to form a composite film with graphene as the framework.
This improves the thermal conductivity and mechanical properties of graphene phase change composite heat dissipation films, simplifies the preparation process, reduces costs, and avoids environmental pollution and damage to graphene sheets.
