Embodiment 1

[0043] A preparation method of a bionic high-adhesion long-acting antibacterial and antifogging agent is prepared according to the following method: first, polyacetamide-dopamine polymer is synthesized according to the mass ratio of dopamine and polyvinylamine at 1:100, and dialyzed with deionized water for three days, After freeze-drying, configure an aqueous solution with a mass fraction of 5%, spray it on the surface of the plastic petri dish and the right side of the goggles surface, and remove the solvent at room temperature to obtain a petri dish and goggles with a polymer coating. The coating film thickness of the anti-fogging agent on the goggles and other lenses is greater than or equal to the thickness of a single polymer layer, and it only needs to not affect the line of sight of the goggles and the like.

[0044] Effect verification:

[0045] Put the blank Petri dish, Petri dish with anti-fog antibacterial coating and goggles next to the humidifier, and after four ...

Embodiment 2

[0048] A preparation method of a bionic high-adhesion long-acting antibacterial and antifogging agent is prepared according to the following method: first, polyethyleneimine-dopamine polymer is synthesized according to the mass ratio of dopamine and polyethyleneimine at 1:10, and dialyzed with deionized water for three After three days and freeze-drying, configure an aqueous solution with a mass fraction of 20%, spray it on the surface of the plastic petri dish and the right side of the goggle surface, and remove the solvent at room temperature to obtain a petri dish and goggles with a polymer coating.

[0049] Effect verification:

[0050] Put the blank Petri dish, Petri dish with anti-fog antibacterial coating and goggles next to the humidifier, and after four hours, test the anti-fog effect.

[0051] By observation, the left side of the blank petri dish and goggles has a layer of water mist on the surface, while the petri dish and goggles coated with anti-fog and antibacter...

Embodiment 3

[0053] A preparation method of a bionic high-adhesion long-acting antibacterial and antifogging agent, which is prepared according to the following method: first, an aqueous solution with a mass fraction of 20% is prepared according to the mass ratio of tannic acid and gelatin at 1:2, and sprayed onto the surface of a plastic petri dish and On the right side of the goggle surface, the solvent was removed at room temperature to obtain a polymer-coated Petri dish and goggle.

[0054] Effect verification:

[0055] Put the blank petri dish, petri dish with anti-fog antibacterial coating and goggles next to the humidifier, and after six hours, test the anti-fog effect.

[0056] By observation, the left side of the blank petri dish and goggles has a layer of water mist on the surface, while the petri dish and goggles coated with anti-fog and antibacterial coating have no water mist on the surface.

Abstract

The invention belongs to the field of biomedical polymer materials, and discloses a preparation method and application of a bionic high-adhesion long-acting antibacterial antifogging agent. The antifogging agent is prepared by the steps that firstly, a hydrophilic bionic high-adhesion polymer is prepared, then the hydrophilic bionic high-adhesion polymer coats a surface to be treated through a solution of the hydrophilic bionic high-adhesion polymer, so as to inhibit surface fogging and bacterium breeding. A hydrophilic bionic high-adhesion polymer solution is prepared by controlling key raw materials, a flow process and the like of the antifogging agent, and the hydrophilic bionic high-adhesion polymer solution can be used as a long-acting antibacterial antifogging agent for antifogging and antibacterial treatment on the surfaces of medical goggles lenses and the like, has good biological safety, and can effectively inhibit fogging and bacterium breeding on the surfaces of the goggles.

Description

technical field [0001] The invention belongs to the field of biomedical polymer materials, and more specifically relates to the preparation and application of a bionic high-adhesion long-acting antibacterial and antifogging agent, and correspondingly can obtain antifogging and antibacterial goggles. Background technique [0002] As the temperature and humidity change, water vapor condenses into water droplets, making goggles, face shields and other protective equipment very easy to fog. Fog will strongly scatter visible light and reduce the light transmittance of goggles, face shields and other protective equipment. It not only affects the accuracy of medical staff's operation, but also increases the psychological pressure. [0003] Although some goggles and face shields are equipped with original anti-fog coatings, their anti-fog coatings are not wear-resistant, and a slight touch with your fingers will greatly reduce the anti-fog effect. Therefore, we often use some comm...
