Claim:
1. A method of forming an adhesive matrix, comprising: establishing a mixture comprising a non-aqueous liquid, a first polyacrylic acid crosslinked with pentaerythritol and/or allyl sucrose, and a second polyacrylic acid crosslinked with divinyl glycol on a substrate, wherein the amount of water in the mixture is less than or equal to about 2 wt. %; applying a non-aqueous polar solvent to the mixture on the substrate, wherein the non-aqueous polar solvent contains at least one of methanol, ethanol, propanol, and butanol; and allowing at least a portion of the non-aqueous liquid and the non-aqueous polar solvent to evaporate to produce the adhesive matrix, wherein, after the evaporation, the sum of the amount of the non-aqueous liquid and the non-aqueous polar solvent in the adhesive matrix is between about 0.001 wt % and about 3 wt %.
