▎ 摘　　要

NOVELTY - A PEEK (RTM: Colorless organic polymer thermoplastic) and polyvinyl alcohol composite bone scaffold performance improving method involves mixing PEEK (RTM: Colorless organic polymer thermoplastic) powder, polyvinyl alcohol powder and graphene oxide powder through liquid phase, solid-liquid separation, drying and grinding the solid to obtain a composite powder, and preparing composite powder by using laser three-dimensional printing technique. USE - Method for improving performance of PEEK (RTM: Colorless organic polymer thermoplastic) and polyvinyl alcohol composite bone scaffold. ADVANTAGE - The method enables improving interface property and better binding ability of the composite bone scaffold.
