Self-decontaminating surface coatings and articles prepared therefrom

摘要

The present invention is directed toward a self-decontaminating surface coating, which when cured has a partially hydrophobic surface. The coating comprises a polymeric coating resin which, when cured, is hydrophilic. The coating also comprises a biocide, a germinating agent, and a hydrophobic micro/nano particulate material. The coating is suitable for application to ceramics, metals, and polymer substrates. Articles coated with the coating of the present invention are resistant to spores.

主权项

1. A self-decontaminating surface coating comprising:
a cured hydrophilic polymeric coating resin; a biocide in an effective amount for the purpose of killing microbial pathogens; a superabsorbent polymer;
wherein a germinating agent and a nutrient are absorbed into the superabsorbent polymer; and hydrophobic particulates having dimensions of less than 100 micrometers protruding from the surface of the cured hydrophilic polymeric coating resin;
wherein the self-decontaminating surface coating when cured has a partially hydrophobic three dimensional surface and is resistant to spores.
