Abstract:
1. A method for activating silicone rubber surfaces comprising steps of: i) swelling at least a surface of a silicone rubber matrix with a silicone rubber swelling solvent; ii) treating the silicone rubber matrix during or after the swelling with a solution comprising at least a reactive silane, wherein the reactive silane comprises at least one hydrolytically labile bond linked to at least one of the Si atoms present in the reactive silane, the reactive silane comprising a reactive silane according to Formula (III), Formula (IV), or Formula (V), thereby forming a treated silicone rubber matrix; and iii) drying and/or heat treating the treated silicone rubber matrix, wherein Formula (III) is: wherein R9 and R10 are independently selected from the group consisting of branched and linear, substituted and unsubstituted alkyl, alkenyl, and alkoxy groups; and wherein R11 is selected from the group consisting of substituted and unsubstituted, saturated and unsaturated, branched and linear aliphatic hydrocarbon groups, substituted and unsubstituted, branched and linear aralkyl groups, substituted and unsubstituted aryl groups, and hydrogen; Formula (IV) is: wherein each R11 may be the same or different and is selected from the group consisting of substituted and unsubstituted, saturated and unsaturated, branched and linear aliphatic hydrocarbon groups, substituted and unsubstituted, branched and linear aralkyl groups, substituted and unsubstituted aryl groups, and hydrogen; and R12 and R13 may be the same or different and are selected from the group consisting of substituted and unsubstituted, branched and linear alkyl and alkoxy groups; and Formula (V) is: wherein R14 is selected from the group consisting of hydrogen, saturated and unsaturated, substituted and unsubstituted aliphatic hydrocarbon groups, and substituted and unsubstituted aryl groups; and R15 is selected from substituted and unsubstituted, branched and linear alkyl groups.
