Abstract

The invention relates to a marine biological antibacterial nano fiber and preparation method thereof. The nano fiber comprises the components of a collagen, a polyvinyl alcohol and an electric contact nano high valent silver oxide; and the mass ratio thereof is 20:20:0.001; the preparation method includes: (1) preparing electric contact nano high valent silver oxide particle antibacterial solution; (2) preparing grass carp skin collagen solution; (3) preparing mixed antibacterial spinning solution of the collagen and the polyvinyl alcohol (PVA); (4) electrostatic spinning on the mixed solution, thus obtaining the marine biological antibacterial nano fiber. The fiber is added with the collagen and electric contact nano high valent silver oxide in grass carp skin tissue, thus having favorable skin compatibility and sterilization property; besides, the operation method is simple, the raw material is available, and the cost is low, thus being applicable to industrialized production.

Description

technical field [0001] The invention belongs to the field of antibacterial nanofibers and their preparation, in particular to a marine biological antibacterial nanofiber and a preparation method thereof. Background technique [0002] In recent years, due to the influence of the tanning industry on the origin of skins and the occurrence and prevalence of infectious diseases such as mad cow disease and foot-and-mouth disease, people have doubts about the safety of collagen derived from terrestrial livestock. Many developed countries have banned the use of collagen extracted from cowhide and bovine bone. At the same time, the application of terrestrial livestock-derived collagen in areas that believe in Islam and Islam is limited. Therefore, this research group turned the focus to marine animal collagen, which has not been effectively industrialized. It can be predicted that collagen derived from fish skin, fish scales and other marine aquatic product processing waste will be...
