“…Reports of hydrogel using silicone were not in abundance. However, Lopour et al 22 reported silicone rubber-hydrogel composites as polymeric biomaterials. In their report, they showed the relations between the properties and the influence of the interaction of polymeric phases on their mechanical properties in the silicone rubber-hydrogel composite materials.…”

Graft copolymerization of epoxy-terminated poly(dimethylsiloxane) (PDMS) onto chitosan was reacted without using a catalyst. pH-sensitive hydrogels were obtained that are based on two different components: a natural polymer and a synthetic polymer. These PDMS substitutents provide the basis for hydrophobic interactions that contribute to the formation of hydrogels. Various graft hydrogels were prepared from different weight ratios of chitosan and PDMS. Swelling behavior of these hydrogels was studied by immersion of the gels in various buffer solution. Photocrosslinked hydrogels exhibited a high equilibrium water content (EWC). Particularly, the sample CP31 of the highest chitosan-PDMS weight ratio showed the highest EWC in time-dependent, temperature-dependent, and pH-dependent swelling behavior.

“…The swollen state of gel is suitable for adsorption, retention or separation of various target substances. Because of these characteristics, they are frequently applied to various medical uses as recently reported (Chen and Park, 2000;Hron et al, 1997;Ichikawa et al, 2003;Lopour et al, 1993;Ludwig, 2005;Russell et al, 2003;Swatschek et al, 2002;Yan and Gemeinhart, 2005). In these applications, these researchers mainly attended to the ability of gel to adsorb, retain and release medical or biological chemicals as they want to control.…”

Poly(vinyl alcohol) (PVA) was dissolved in the water to make a 10 wt % aqueous solution, and polydimethylsiloxane (PDMS) was mixed with 1 wt % 2,2-dimethyl-2-phenylacetophenone (DMPAP) and 0.5 mol % methylenebisacrylamide (MBAAm) in isopropyl alcohol. This mixture was added to a PVA aqueous solution and heated at 90°C for 7 h. Various crosslinked networks were prepared at different molar ratios of PVA/PDMS (1:1, 1:3, and 3:1). The characterization of PVA/PDMS crosslinked networks was determined by Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), a universal testing machine (UTM), and the equilibrium water content (EWC). The DSC melting endotherms showed, at 219.49°C, a sharp endothermic peak of PVA, and PVA/PDMS crosslinked networks had melting peaks close to this point. The value of EWC increased with the content of PVA in the crosslinked networks, simultaneously depending on the temperature. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 85: 957-964, 2002
