Abstract: 
Semi-interpenetrating networks (sIPNs) are a type of polymer networks in which one polymer is crosslinked in the presence of a linear polymer solution. The materials used in this case are the poly(ionic liquid) (PIL), tributylhexyl phosphonium 3-sulfopropyl acrylate (PSPA) as the crosslinked matrix while the linear polymer is a poly(N-isopropylacrylamide-co-spiropyran-co-acrylic acid) p(NiPAAm-BSP-AA) copolymer, which is both thermo- and photo- responsive. The research described herein focuses on determining the influence of temperature, white light and salt concentration on the are of the sIPN hydrogels swollen in deionized water (DI water). The area shrinkage was calculated using the following formula: %s = (Ai - Af)/Ai x 100, where Ai is the White-light Induced Shrinking initial area of the swollen hydrogel and Af after the application of the stimulus.
