▎ 摘　　要

NOVELTY - Composite cooling film, comprises a three-dimensional self-assembled thermally conductive and flame-retardant network structure which is constructed from two-dimensional nanomaterials and one-dimensional nanomaterials, and an ionic halides which are adsorbed on the three-dimensional framework formed by one-dimensional nanomaterials and two-dimensional nanomaterials. The two-dimensional nanomaterials include hexagonal-boron nitride, aluminum nitride, molybdenum disulfide, and/or graphene. USE - The cooling film is useful in battery and electronic device (claimed) ADVANTAGE - The design of the three-dimensional porous structure is good for increasing the ion halide and the air of the contact, ensuring the ionic halide fully absorbing water. The film and the battery have better contact, effectively reducing the interface thermal resistance, improving the heat conducting ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of composite radiating film.
