ABSTRACT
Current surgical dressings and woundplast have drawbacks such as poor permeability, airtightness and biocompatibility, thus a new material is obligatory to replace the traditional ones. Due to outstanding biocompatibility of Silk Fibroin (SF) and excellent antibacterial properties of Dodecyl Trimethyl Ammonium Bromide (DTAB), a cationic surfactant, the SF/DTAB hydrogel formed instantaneously is recommended. By means of SEM, FTIR and XRD, SF/DTAB hydrogel displayed clustered nanofilaments structure and similar secondary structure and morphology with SF solution mainly consisted of random coils in 1 h, then it tended to be the same as pure SF hydrogel which was composed of porous network structure and primarily contained β-sheet structure. Excellent elasticity and antibacterial effect were verified by rheological and antibacterial measurements.
