| titleOfInvention | A kind of modified γ-polyglutamic acid anti-fog coating material and preparation method and application thereof |
| abstract | The invention discloses a modified γ-polyglutamic acid anti-fog coating and a preparation method and application thereof. The preparation method comprises: adding equimolar EDC and NHS to an aqueous solution of γ-polyglutamic acid, and adjusting the concentration of the solution. The pH value is 4.0~6.0, stirring for 0.5~2h; dopamine hydrochloride is added, the molar ratio of dopamine hydrochloride and glutamic acid monomer is 0.1~1:1, and the reaction is dark for 8~24 hours under the protection of inert gas; the small molecules are removed by dialysis material, that is. The product prepared by the invention, on the surface of the material, can obtain an anti-fog film that is firmly bonded to the base material by in-situ polymerization, effectively improving the defects of poor adhesion of the previous anti-fog coating and rapid decay of the anti-fog performance, and does not affect the original It has the light-transmitting properties of the material, and has broad application prospects in the fields of resin lenses, food packaging materials, agricultural film and plastic films. |
