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
