Abstract:In order to develop a natural and harmless antibacterial finishing agent which is beneficial to human body, silk fibroin/chitosan microspheres were prepared by emulsion polymerization. The microscopic morphology, chemical structure, thermal stability and antibacterial properties of the microspheres with different ratios of silk fibroin and chitosan were examined. The results show that the silk fibroin mass fraction is 6%, the chitosan mass fraction is 3%, and the volume ratio of chitosan to silk fibroin is 1∶2, the microspheres have a spherical shape and smooth surface with particle size between 0.4 to 1.4 μm. In addition, it has a good antibacterial effect against Escherichia coli and Staphylococcus aureus, with the antibacterial ratio of(82 ± 4.2)% and(80 ± 2.6)%, respectively. The secondary structure of the microspheres changes from silk I to silk II, and the initiation temperature of thermal decomposition is higher than 250 ℃, showing good thermal stability.
Keywords:silk fibroin  chitosan  microsphere  antibacterial property  emulsion polymerization
