摘要: An aqueous antimicrobial coating composition capable of forming an antimicrobial coating on a surface comprises at least two organosilanes, each of the at least two organosilanes having a structure, R—Si(OR′)3 wherein R=—(CH2)3—Y; Y=+—N(CH3)2(C18H37)X−; +—N(CH3)2(C14H29)X−; +—N(C10H21)2(CH3)X−; —Cl or —NH2; X−=halide, sulfate, nitrate, phosphate, carbonate, organic sulfonate, organic carbonate, BF4−, or ClO4−; and R′=H, methyl or ethyl, or a C3-C6 straight-chained, branched or cyclic alkyl group, with the proviso that the organosilane R—Si(OR′)3 having the C3-C6 straight-chained, branched or cyclic alkyl group hydrolyzes in the aqueous antimicrobial coating composition to R—Si(OH)3.

摘要: Aqueous antimicrobial coating compositions are disclosed comprising at least one organosilane homopolymer, present as a distribution of polymer chain lengths, and optionally at least one amine. A method of preparing an antimicrobial coating comprises coating a surface with the aqueous antimicrobial coating composition and allowing the composition to dry into a film that exhibits residual antimicrobial efficacy against microorganisms even after mechanical abrasion of the coating. The organosilane homopolymer may comprise only 3-aminopropylsilanetriol homopolymer, mixtures of 3-aminopropylsilanetriol homopolymer, 3-chloropropylsilanetriol homopolymer and 3-(trihydroxysilyl)propyl dimethyloctadecyl ammonium chloride homopolymer, or any one of various unique organosilane homopolymers having multiple amine functionality.

摘要: A method of quantifying an antimicrobial coatings using a handheld XRF analyzer is disclosed. The method provides an estimate of the expected level of antimicrobial efficacy for a thin film comprising silicon and/or titanium by obtaining a 14Si or 22Ti peak intensity using XRF spectroscopy and converting the obtained 14Si or 22Ti peak intensity to the expected level of efficacy using a calibration curve. A properly calibrated handheld XRF analyzer allows a user to assess the viability of antimicrobial coatings in the field, such as in a hospital where various fomites may be coated with silane and/or titanium compositions.
