摘要: A series of novel polyampholyte superabsorbent nanocomposites with excellent gel strength were synthesized by in situ solution polymerization aqueous solution. Acrylic acid and acryloyloxyethyl trimethyl ammonium chloride (DAC) employed as ionic monomers montmorillonite (MMT) was used inorganic component. The addition cationic component could supply the positive charge network nanocomposite promote formation nanostructure composites due to interaction between DAC clay platelets. performance investigated result showed that hydrogel distilled water 0.9 wt% NaCl reach 198.85 204.23 mJ/g, respectively, which 13 times matrix. investigation swelling behaviors had particular polyampholytes different pH values concentration NaCl.
