【 摘 要 】

This paper reports the synthesis of nanostructured hydrogels of acrylamide by a two-step polymerisation process. The first step is performed by inverse microemulsion polymerization (water-in-oil) of N-isopropylacrylamide (NIPA), with these particles then added to aqueous solutions of acrylamide (AM), adding a crosslinking agent. The polymerization reaction is then initiated, thereby producing nanostructured hydrogels. We determined the capacity to absorb water, water and / or ethanol when nanostructured hydrogels were immersed in aqueous solutions with different concentrations of ethanol. It was found that the hydrogels were selective in absorbing water in all cases increasing with the ethanol concentration of the solutions.
