▎ 摘　　要

NOVELTY - A polymer composition comprises polymer dendritic colloid solutions and inorganic fillers. The mass ratio of the polymer in polymer dendritic colloid solution to the inorganic filler is 1:1-1:40. USE - Polymer composition used as raw material for preparing flexible self-supporting films in flexible devices e.g. flexible thermoelectric material device, flexible elastic conductor, flexible heat-conducting material, flexible dielectric material or flexible lithium battery negative electrode material (all claimed). ADVANTAGE - The polymer composition uses polymer-like dendritic colloid solution to achieve excellent dispersion and distribution of high-content inorganic fillers. The polymer composition provides flexible self-supporting film with high inorganic filler content, and excellent flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of flexible self-supporting film, which involves mixing the polymer dendritic colloid solutions and inorganic fillers, obtaining polymer composition, and forming into a film.
