主　　题：silk fibroin piezoelectric fiber dry-spinning conformation transition 

摘      要：The self-powered tissue engineering scaffold with good biocompatibility is of great significance for stimulating nerve cell *** this study,silk fibroin(SF)-based fibers with regulatable structure and piezoelectric performance are fabricated by dry-spinning and *** concentration of SF and calcium ion in spinning dope and the post-treatment affect the conformation transition and crystallinity of *** a result,the SF fibers exhibit high piezoelectric coefficient d_(33)(3.24 pm/V)and output voltage(~27 V).Furthermore,these piezoelectric fibers promote the growth of PC-12 cells,demonstrating the promising potential for nerve repair and other energy harvester.
