| Abstract: | Addition of the surfactant, sodium dodecyl sulphate well below the critical micelle concentration facilitates cross-linked networks in the polyvinyl alcohol-borax hydrogel, while at a concentration higher than the CMC, surfactant micelles start destabilizing the cross-linking in the gel network. The PVA-borax hydrogel shows an increased elastic behavior, in particular at lower SDS concentration and Maxwellian fluid behaviour at lower concentration of both SDS and TX-100. Inclusion of SDS in the hydrogel also significantly lowers the gel-sol transition temperature. |
