Study on superabsorbent composite XVI. Synthesis, characterization and swelling behaviors of poly(sodium acrylate)/vermiculite superabsorbent composites

Vermiculite: Structural Properties and Examples of the Use

“…The incorporation of clays reduces production cost, and also improves the properties (such as swelling ability, gel strength, mechanical, and thermal stability) of superabsorbents and accelerates the generation of new materials for special applications. The properties of traditional superabsorbent could be enhanced by incorporating vermiculite [125]. It is expected that organomodification of vermiculite can further improve dispersion and performance of the resultant nanocomposite.…”

Preparation and characterization of a novel pH-sensitive chitosan-g-poly (acrylic acid)/attapulgite/sodium alginate composite hydrogel bead for controlled release of diclofenac sodium

“…For example, Zheng, Li, Zhang, and Wang (2007) synthesized nanocomposite hydrogel with high thermal stability by grafting acrylic acid onto the vermiculite. Liu et al (2007) reported the preparation of CTS/clay nano-composite hydrogel with excellent anti-fatigue property, and continuous and steady release for vitamin B 12 by introducing the negatively charged delaminated montmorillonite.…”

Evaluation of ammonium removal using a chitosan-g-poly (acrylic acid)/rectorite hydrogel composite

“…Considering the limitations of pure polymeric hydrogels, such as poor gel strength and stability, some inorganic clay minerals including attapulgite, montmorillonite, vermiculite and sepiolite have been incorporated into hydrogel matrix [17][18][19][20]. Clays are natural, abundant, and inexpensive materials that have high mechanical strength and chemical resistance.…”
