✦ Synopsis
Terephthaloyl chloride (DB)-modified silk fibroin (SF) films were immersed into 1.5 times simulated body fluid (1.5 SBF) to regulate the mineralization of hydroxyapatite (HA) crystals at about 36.5 8C for 24 h. UV was used to prove that the new bonds form between the DB and SF. The structure and morphology of the SF/HA were investigated by FTIR, ICP, XRD and SEM. The results showed that the apatite deposited on the matrix of SF mainly was HA. HA was self-assembled on the matrix of SF and formed threedimensional framework when the weight ratio of DB/SF was 0.30. The content of DB affected the structure and morphology of the apatite composites deposited on the SF films.
