Preparation, characterization and biopotential using properties of new biohybrid hydrogels containing zeolite

In this study, it was synthesized that the new biohybride hydrogels by using acrylamide monomer, sodium vinylsulfonate as a comonomer, zeolite and a natural polymer such as sodium carboxymethyl cellulose. Polymeric hydrogels were prepared by free radical polymerization in aqueous solution using poly (ethylene glycol) diacrylate as a crosslinker. Structural characterization of prepared chemically crosslinked polymers were tried to determine by using Fourier Transform Infrared Spectroscopy/Attenuated Total Reflectance (FT-IR/ATR). SEM micrographs were taken for determination of surface porosity of hydrogel systems. Dynamic water/liquid sorption tests were applied at 25oC for the purpose of investigation of water/liquid sorption properties of biohybride hydrogels and semi-IPN hydrogels. According to obtained data, parameters concerning swelling kinetics and diffusion mechanism were calculated. A cationic dye such as methyl violet was selected as model molecule to investigate of adsorption properties of biohybrid hydrogels and semi-IPN hydrogels. It was determined that crosslinked biohybrid hydrogels and semi-IPN hydrogels have adsorbed dye of methyl violet from aqueous solutions in high level.
