1. A method of preparing a silicone-acrylate hybrid composition, said method comprising:
combining a silicone article and an acrylate composition to form a swollen silicone material comprising the acrylate composition dispersed in the silicone article; and
irradiating the swollen article to polymerize the acrylate composition and give the silicone-acrylate hybrid composition, wherein the step of irradiating is carried out in the absence of any solvent;
wherein the acrylate composition comprises:
an acrylate compound having the general formula (A):

OG Complex Work Unit Chemistry
wherein each R is independently selected from H and substituted or unsubstituted hydrocarbyl groups, R1 is H or a substituted or unsubstituted hydrocarbyl group having from 1 to 10 carbon atoms, n is an integer equal to or greater than 1, and R2 is selected from R1, an amine group, an alkoxy group, an alkyl group, an alkyl group substituted with a hydroxyl group or an amino group, or a moiety having a valency of n greater than 1 to 4; and
an initiator;
wherein the silicone-acrylate hybrid composition comprises a solid interpenetrating polymer network.
