Multifunctional sensors based on silicone hydrogel and their responses to solvents, pH and solution composition

Polymer International Vol. 66 No. 4 pp. 566-572 · Wiley
Abstract
AbstractIn this paper, multicomponent silicone hydrogels were prepared by the copolymerization of the hydrophobic silicon‐containing monomer bis(trimethylsilyloxy) methylsilylpropyl glycerol methacrylate with two hydrophilic monomers 2‐hydroxyethyl methacrylate and N‐vinyl pyrrolidone. The response of the silicone hydrogels to different stimuli was evaluated by observing the swelling ratios of the hydrogels. The results show that the hydrogels display different responses to variations in pH and solvent. Multifunctional sensors were then prepared based on the silicone hydrogels to detect the pH value of solutions, the types of solvent and the ethanol percentage in water. The results could be obtained by visual inspection and the sensors were reusable. © 2016 Society of Chemical Industry
