The invention relates to a preparation method of an antibacterial silk
fibroin fibrous membrane. The preparation method comprises the following steps: dissolving silver salt into water and adding aqua
ammonia to form clarifying transparent silver ammino and an
ionic solution firstly; adding water-insoluble
fatty alcohol, and adopting a
microwave irradiation technology to prepare silver nanoparticles; adding the obtained silver nanoparticles into a prepared silk
fibroin solution, mixing the obtained silver nanoparticles and the prepared silk
fibroin solution, so as to form a
spinning solution; then preparing the antibacterial silk fibroin
fibrous membrane through a static
spinning technology. According to the preparation method provided by the invention, the method is simple, an interface
system is regarded as a reaction medium, so that the products can be transferred between different phases, the surface adsorbent can be replaced, and good uniformity of the nanoparticles can be guaranteed; the
microwave irradiation technology is adopted, so that the
crystallization speed of the products can be improved, the operating steps are simple, the cost is low, the
reaction speed is high, the efficiency is high, and a certain universality is provided; the nano-silver has hydrophobicity and can be dispersed into the silk fibroin solution very well, which is further in favor of preparing antibacterial silk fibroin membrane with good uniformity.
