Abstract: This review starts with a brief introduction of the principles and methods of electrospinning technique as well as their applications in the preparation of composite nano-biomaterials. The use of electrospinning technique can add new features to materials by combining variety of substances into one single nanofiber, which has acquired extensive attention in the field of the synthesis of multifunctional composite materials and showed a great potential. Sodium alginate nanomaterials with excellent physiochemical properties, functional characteristics, biocompatibility and specific nano-size effects can be fabricated into antibacterial composite films using silver nanoparticles as the antibacterial agent based on elecrospinning technique. These films play an important role in food packaging, wound dressing, drug delivery and tissue engineering scaffold. Additionally, a couple of problems such as how to optimize the modifier of sodium alginate, how to choose antibacterial agent etc. are introduced and application perspective of electrospinning technique on the preparation of sodium alginate antibacterial composite films is discussed.

Key words: sodium alginate, electrospinning, antibacterial, composite films, nanomaterials

摘要： 概述了静电纺丝技术的原理及其在生物性纳米复合材料制备过程中的作用.该技术可将多种材料以不同的方式复合到同一根纤维中,使得纤维又增添了多种新的功能,因此其在多功能复合材料制备方面的应用广受关注.同时由于海藻酸钠纳米材料具有良好的理化性质、功能特性、生物相容性及特殊的纳米效应,利用静电纺丝技术将高效抗菌剂均匀分布到海藻酸钠材料中制备成抗菌复合薄膜,使其在食品包装、创伤敷料、药物载体及组织工程支架等方面体现出了重要的应用价值.此外,本文还在该技术的基础上,提出了关于静电纺丝制备海藻酸钠抗菌复合薄膜过程中改性剂的优化、抗菌剂的选择等方面的问题,并展望了基于静电纺丝技术的海藻酸钠抗菌复合薄膜的应用前景.
