Preparation and Characterization of SF/Gel Ma Electrospinning Nanofiber Materials

为改善甲基丙烯酸酰化明胶(Gel Ma)静电纺丝纳米纤维材料的力学性能,文中采用丝素蛋白(SF)与Gel Ma共混,通过静电纺丝和双重固化技术制备SF/Gel Ma纳米纤维材料。研究结果表明:SF/Gel Ma纳米纤维材料具备紫外光固化能力和纳米级纤维结构,SF可改善Gel Ma纳米纤维材料的断裂强度和可拉伸性,其断裂强度由0.86 MPa提升至最大5.13 MPa,最大拉伸率由84%提升至最大186%,同时SF/Gel Ma纳米纤维材料的亲水性得到提高。制备的SF/Gel Ma纳米纤维材料在生物医学领域具有应用潜力。

In order for the mechanical properties of methyl acrylic gelatin(Gel Ma)electrospunning nanofibrous materials to be improved,silk fibroin(SF)was blended with Gel Ma to produce SF/Gel Ma nanofibrous materials through electrospinning and two step curing procedure.The results show that the SF/Gel Ma nanofibrous materials exhibit a UV curing capability and nanoscale fibrous structure.SF can effectively improve the mechanical strength and stretchability of Gel Ma nanofibers,with their tensile strength increased from 0.86 MPa to 5.13 MPa and their stretchability increased from 84%to 186%.Their hydrophilic properties are also improved.The SF/Gel Ma nanofibrous materials are expected to find potential applications in the biomedical field.
