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

Abstract

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.

Comparison of Mechanical Properties of Unidirectional and Woven Carbon, Glass and Aramid Fiber Reinforced Epoxy Composites

“…Mechanical properties of fiber reinforced composites in these studies are investigated experimentally, numerically and analytically [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. There are also some studies on basalt fiber and hydrojel composites [19,20] Frangopol et al investigated the reliability of a composite laminate plate by using Tsai-Wu failure criterion. Fiber orientation, layer thickness and number have a significant effect on the reliability of fiber reinforced composite plates [3].…”

Poly(2-acrylamido-2-methyl-1-propane sulfonic acid-co-1-vinyl-2-pyrrolidone) Hydrogel and its use in the Removal of Cd(II), Pb(II) and Cu(II)

“…The removal of heavy metals has become a major problem since they do not have a biodegradable property naturally in the environment [1]. Hydrogels, hydrophilic, cross-linked and three-dimensional networks, have an excellent water absorbing capacity without being soluble [3][4][5]. These smart materials are widely used in the removal of heavy metal ions because of the presence of the functional groups (i.e.…”

Oxidation of Cyclohexene with H2O_2 Catalyzed by Vanadium Based Polyoxometalates Doped Modified Clays as Green Catalysts

“…It is a 2:1 aluminosilicate, the unit layer structure of which consists of one Al 3+ octahedral sheet between two Si 4+ tetrahedral sheets [11]. Montmorillonite was also used in different fields [12][13][14][15] Montmorillonite derived from Hammam Boughrara, Maghnia, Algeria and treated by HCl acid activation were used as supports for PVMo. The oxidation of cyclohexene, using hydrogen peroxide as an oxidant was selected to evaluate their catalytic performance.…”
