丝素蛋白（SF）是一种可生物降解的蛋白质，具有优异的亲肤性、生物相容性、低免疫原性和无毒性。然而，SF 有一系列缺点。例如，SF在水过滤中的应用因其吸附重金属离子的能力不足而受到限制。它本身并不抗菌，因此 SF 作为过滤器无法有效消除空气中的细菌。不具有导电性的 SF 不适用于传感器和摩擦纳米发电机。在组织工程中，机械和抗炎特性的不足也会影响伤口的恢复速度。而物理和化学改性将改善其应用性能并拓宽其应用领域。该综述描述了通过填充、共混、结构调整、后处理、交联、接枝和原位聚合对SF进行改性，以赋予其其他功能特性。讨论了通过各种方法（例如湿/干/微流体纺丝、静电纺丝）制备的改性SF纤维，它们可用于水/空气过滤、化学/压力/应变传感器、摩擦纳米发电机、人造皮肤、伤口敷料和组织支架。最后对改性SF纤维的发展趋势进行了展望。该综述对于如何利用改性SF纤维提高过滤效率、传感器性能和伤口恢复具有参考意义。

Progress in Research and Application of Modified Silk Fibroin Fibers

Silk fibroin (SF) is a biodegradable protein and possesses superior skin-friendliness, biocompatibility, low immunogenicity, and non-toxicity. However, SF has a series of drawbacks. For example, the application of SF in water filtration is limited by its inadequate ability to adsorb heavy metal ions. It is not inherently antibacterial, making SF ineffective as a filter to eliminate airborne bacteria. SF without conductivity is not suitable for use in sensors and triboelectric nanogenerators. In tissue engineering, deficient mechanical and anti-inflammatory properties also have an influence on the rate of wound recovery. While physical and chemical modifications will improve its application properties as well as broaden its application areas. This review describes the modification of SF by filling, blending, structural adjustment, post treatment, crosslinking, grafting, and in situ polymerization to provide it with other functional properties. Modified SF fibers prepared by various methods (e.g., wet/dry/microfluidic spinning, electrospinning) are discussed, and they can be used in water/air filtration, chemical/pressure/strain sensors, triboelectric nanogenerators, artificial skin, wound dressings, and tissue scaffolds. Finally, the development trend of the modified SF fibers is prospected. This review has a reference significance on how to use modified SF fibers to improve filtration efficiency, sensor performance, and wound recovery.
