▎ 摘　　要

NOVELTY - Functional coating, comprises a core-shell structure, where the core of the core-shell structure is micronsized polymer. The shell of the core-shell structure is functionalized filler. The thickness of the shell is 50-200nm USE - The functional coating is useful as coating material in modification of polymer surface (claimed). ADVANTAGE - The coating : has strong interface effect, mechanical and chemical stability; can reduce the raw material added with polymer to the functional caused by adverse effect; and ensure the content of the filler to 90 wt.%. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the functional coating comprising mixing the micelle solution containing micron-sized polymer with functionalized filler to obtain the final product; and (2) functional coating prepared by the above preparation method.
