Method for fabrication of silicone composite with antimicrobial coating

Abstract

An antimicrobial article prepared by a method includes forming an antimicrobial mixture by adding a calculated amount of antimicrobial agent to a solution of water and alcohol, depositing the antimicrobial mixture in a container, the antimicrobial mixture having a thickness of 0.1 μm to 10 μm, evaporating the water and alcohol of the antimicrobial mixture to form the layer of antimicrobial coating, adding silicone resin on top of the layer of antimicrobial coating and allow the silicone resin to permeate and crosslink with the layer of antimicrobial coating, and removing the silicone composite with the layer of antimicrobial coating from the container.

1 . An antimicrobial article prepared by a method comprising:
 forming an antimicrobial mixture by adding a calculated amount of antimicrobial agent to a solution of water and alcohol;   depositing the antimicrobial mixture in a container, the antimicrobial mixture having a thickness of 0.1 μm to 10 μm;   evaporating the water and alcohol of the antimicrobial mixture to form the layer of antimicrobial coating;   adding silicone resin on top of the layer of antimicrobial coating and allow the silicone resin to permeate and crosslink with the layer of antimicrobial coating; and   removing the silicone composite with the layer of antimicrobial coating from the container.   
     
     
         2 . The antimicrobial article according to claim  5 , wherein the antimicrobial agent includes silver ion-containing sodium zirconium phosphate/zeolite, zinc oxide or titanium dioxide. 
     
     
         3 . The antimicrobial article according to claim  5 , wherein the silicone resin is room temperature vulcanizing (RTV) silicone rubber. 
     
     
         4 . The antimicrobial article according to claim  5 , wherein the solution of water and alcohol has a ratio of 1 to 3.
