Molecular interactions in polyacrylamide/lithium perchlorate hydrogel composites

In this study, the effects of introduction of lithium perchlorate into polyacrylamide hydrogels having constant amounts of acrylamide monomers and N,N'-methylene-bis-acrylamide crosslinker have been studied through the observed changes in the vibrational Raman spectra. The changes in the perchlorate anion's Raman modes show that in the polymeric matrix most of the lithium and perchlorate ions are separated by t...
