Abstract
The invention discloses a nanometer silk fibroin-nano-silver antibacterial composite material and a preparation method thereof. A nanometer silk fibroin membrane is used for reducing silver nitrate in situ so as to prepare the nanometer silk fibroin-nano-silver antibacterial composite material, the nanometer silk fibroin-nano-silver antibacterial composite material is washed by deionized water for five times and then is air dried at room temperature so as to obtain the nanometer silk fibroin-nano-silver antibacterial composite membrane. The nanometer silk fibroin-nano-silver antibacterial composite membrane can be widely used in fields such as food packaging, hygienic products, and medical materials.
Description
Technical field
The present invention relates to the invention belongs to nano material, anti-biotic material technical field, be specifically related to a kind of nano thread fibroin-nanometer silver antimicrobial matrix material.
Background technology
Bacterium is ubiquitous, all-pervasive, their propagation and spread the health that the mankind in serious threat.Along with a large amount of uses of the chemicalses such as microbiotic, sterilizing agent and sterilant, the bacterial dissociation population being caused by resistance is more and more, and the global bacterium Disaster Event causing thus occurs again and again.For suppressing the generation of this bacterioid disaster, research and development and application novel antibacterial material are imperative.Anti-biotic material is mainly divided into inorganic antibacterial material, organic anti-bacterial material, organic-inorganic composite antimicrobial material at present.
Along with people constantly increase the requirement for all kinds of anti-biotic materials, the exploitation of anti-biotic material has obtained unprecedented attention, the emphasis of paying close attention to and the main growth point of demand are organic polymer anti-biotic materials, now just at the antibiotic polymer material of extensive exploitation, adopt respectively the technological line that adds inorganic salt antiseptic-germicide and organic compound antiseptic-germicide, but organic synthesis antimicrobial additive all belongs to organic compound, its volatility, perviousness and transport property are strong, exist and easily lose efficacy and hygienic safety hidden danger.
Summary of the invention
For addressing the above problem, the invention discloses a kind of nano thread fibroin-nanometer silver antimicrobial matrix material.
Preparation nanometer fibroin protein film, and utilize nano thread fibroin film in-situ reducing Silver Nitrate to prepare nano thread fibroin-nanometer silver antimicrobial composite membrane, concrete steps are as follows:
(1) the nanometer silk fibroin water solution that preparation quality concentration is 2-5%, dropwise adds sodium hydrate regulator solution pH to 8 under stirring, then prepare nanometer fibroin protein film;
(2) nanometer fibroin protein film step (1) being obtained is immersed in the silver nitrate solution that concentration is 5 ~ 10 mg/mL, and soak time is 1 – 2.5h;
(3) the nanometer fibroin protein film immersed with silver nitrate solution step (2) being obtained is exposed under sunlight, and illumination action time is 1-5h; With deionized water wash 5 times, room temperature is dried; Obtain nano thread fibroin-nanometer silver antimicrobial composite membrane.
Further, the application that described nano thread fibroin-nanometer silver antimicrobial matrix material can be in food product pack, sanitary product, medical material.
Positively effect of the present invention is: without additional other chemical reagent, pollute few.Reaction conditions is gentle, without severe condition such as High Temperature High Pressure, and good energy-conserving effect.Prepared nanometer silver particle diameter little (about 5-7 nm), size distribution are even.Little particle diameter has higher specific surface area, also just means higher anti-microbial activity and lower consumption.Nanometer silver good stability, places and still can keep good dispersiveness, and can dissolve each other with plurality of reagents half a year, therefore has Application Areas widely.Nano thread fibroin is as mould material matrix, and biocompatibility and biological degradability are good.Antibacterial high efficiency, in material 2 h that silver-colored mass concentration is 1%, sterilizing rate can reach more than 99.9%.Broad-spectrum antibacterial property, prepared anti-biotic material has all shown excellent resistance for gram-positive microorganism and Gram-negative bacteria.
