| 摘 要： | 采用碳酸钠溶液对蓖麻蚕丝纤维脱胶,将脱胶后的蓖麻蚕丝素溶解于一定浓度的硫氰酸锂溶液中,透析成膜.然后将丝素膜溶解于六氟异丙醇,利用静电纺丝法制得再生蓖麻蚕丝素蛋白非织造网.通过扫描电镜观察非织造网的形态结构,红外光谱、X-射线衍射、热分析(DTA/TG)分析纤维的聚集态结构变化.研究结果表明,再生蓖麻蚕丝素蛋白非织造网纤维直径大约在几微米,与天然丝素相比其聚集态结构有较大变化.

| Abstract: | Silks were boiled in an aqueous solution of sodium carbonate to extract the sericin proteins.The extracted silk was dissolved in a limited concentration LiSCN solution and dialyzed in water.Then cast it on polystyrene dish surfaces to make films. The films were carried out in HFIP, and we prepared non-woven web of regenerated Samia cynthia ricini silk fibroin fibers with electrospinning method.The morphology of the non-woven web were investigated by SEM, and polymeric structure of the electrospun fibers were analyzed by FTIR,X-ray and DTA/TG.The result showed that the diameter of the non-woven web fibers from the regenerated Samia cynthia ricini silk fibroin were about several micrometers,and the polymeric structure was great different from natural silk fibroin. |
