Preparation and Swelling Properties of Zeolite-Poly(2-hydroxyethyl methacrylate-co-acrylic acid) Hydrogel Composites

Zeolite–Poly(2-hydroxyethyl methacrylate (HEMA)-co-acrylic acid (AA)) hydrogel composite materials were synthesized by in situ free radical addition polymerization technique. The swelling values obtained highly for the hydrogel are synthesized at HEMA/AA monomer ratio value of 80/20. The hydrogel composites synthesized with zeolite having –90 μm particle size and 20 wt% amount showed the highest swelling degree. Zeolite adding to the hydrogel structure increased the swelling values of hydrogel. Synthesized samples were characterized using a Fourier transform infrared spectrometer technique.
