Antimicrobial coatings formed from mixtures of silanes and amines
An anti-microbial coating formulation consisting essentially of triethanolamine and a silane.
1. An antimicrobial coating, formed by a method comprising:
(a) providing a mixture of:
(i) an organosilane of structure (1),
wherein R1 is —H or -Alkyl; and R2 is γ-chloropropyl- or γ-aminopropyl;
(ii) triethanolamine; and
(iii) methanol;
(b) spraying said mixture onto a substrate surface; and
(c) allowing at least about 90% by weight of the methanol to evaporate from the surface to form said antimicrobial coating on said substrate.
2. The antimicrobial coating of claim 1 , wherein said substrate is stainless steel.
3. The antimicrobial coating of claim 2 , wherein R1 is —H and R2 is γ-chloropropyl, and wherein said antimicrobial coating exhibits 100.00% reduction in murine norovirus 1 hour after initial inoculation of the coating with murine norovirus.
4. The antimicrobial coating of claim 2 , wherein R1 is —H and R2 is γ-aminopropyl, and wherein said antimicrobial coating exhibits 100.00% reduction in murine norovirus 1 hour after initial inoculation of the coating with murine norovirus.
5. The antimicrobial coating of claim 1 , wherein said antimicrobial coating comprises a polymer having structure (10),
wherein n is from about 1 to about 10.
6. The antimicrobial coating of claim 1 , wherein said organosilane is tetraethylorthosilicate.
7. An antimicrobial coating, formed by a method comprising:
(a) providing a mixture of:
(i) an organosilane of structure (1),
wherein R1 is —H or -Alkyl; and R2 is γ-chloropropyl- or γ-aminopropyl;
(ii) diethanolamine; and
(iii) methanol;
(b) spraying said mixture onto a substrate surface; and
(c) allowing at least about 90% by weight of the methanol to evaporate from the surface to form said antimicrobial coating on said substrate.
8. The antimicrobial coating of claim 7 , wherein said organosilane is tetraethylorthosilicate.
