利用 Al3＋对骨胶进行改性,制备了 Al3＋改性骨胶粘合材料(CA).研究了 Al3＋对骨胶的改性机理,利用FT-IR(傅立叶转换红外)光谱,XRD(X 射线衍射)光谱,PL(荧光发射)光谱,XPS(X射线衍射光电子)能谱对改性机理进行验证,通过扫描电子电镜(SEM),表面润湿角检测仪对 CA 进行耐水性表征.结果表明,Al3＋与骨胶分子肽链中的—NH 和??O 发生配位反应,使骨胶分子各肽链之间通过 Al3＋交联在一起,形成稳定的五元环网状结构；CA 膜表面较骨胶膜表面更加规整、平滑、致密；表面润湿角检测发现CA膜的接触角为92．45°,而骨胶膜的接触角只有42．58°.
In the thesis,Al3+ modified bone glue adhesive material (CA)was prepared through adopting Al3+ to modify bone glue.Studied the modification mechanism of Al3+ on the bone glue,the modification mechanism was verified through adopting the FT-IR,XRD,PL and XPS,CA was conducted for water-proof representation through adopting SEM and a surface wetting angle detector,and the testing result showed that Al3+ reacts with the and of the peptide chains of bone glue molecules to enable the peptide chains of the bone glue molecules to be cross-linked through Al3+ to form a stable net structure with five-membered rings;the CA membrane sur-face is more neat,smooth and dense than the bone glue membrane surface and the bone glue membrane;the surface wetting angle test indicated that the contact angle of CA was 92.45°and the contact angle of the bone glue membrane was only 42.58°.
