▎ 摘　　要

NOVELTY - Application of terminal olefin-based modified nanofiller as crystallization nucleating agents in the preparation of polylactic acid composite material, is claimed. USE - Application of terminal olefin-based modified nanofiller as crystallization nucleating agents in preparation of polylactic acid composite material (claimed). ADVANTAGE - The terminal olefin-based modified nanofiller is added into the polylactic acid, so that the crystallization nucleation efficiency of the polylactic acid can be improved and the crystallinity of the polylactic acid can be further improved under the condition of not adding plasticizer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polylactic acid composite material, which involves mixing polylactic acid, terminal olefin-based modified nanofiller and organic peroxide, and mixing.
