系统分析了羟基磷灰石(HA)的制备方法和丝素蛋白纤维(SF)的溶解方法,提出一种制备纳米丝素蛋白/羟基磷灰石生物复合材料(SF/HA)的新型反应复合方法--"一步法".并对由"一步法"制得的SF/HA分别进行了钙磷比测定、红外光谱测试、透射电镜观察和x射线衍射测试.结果表明:SF/HA中的钙磷比是1.6692,与标准HA中的钙磷比1.67一致;SF/HA中同时含有SF和HA中各自的官能团;SF/HA的晶粒横向尺度小于100nm,SF/HA呈针状或柱状晶粒,SF和HA能够形成复合;SF/HA的晶型属于六方晶系,当SF在SF/HA中所占质量分数为10%时,晶胞参数a=b=9.0319(A),c=7.0148(A),沿c轴方向平均品粒尺寸是230.7645(A)."一步法"制备SF/HA具有合理性和可行性.
