Preparation of poly(Y-glutamic acid)/montmorillonite superabsorbent nanocomposite

摘要：

　　Montmorillonite (MMT) was applied as the modifying agent,polyethylene glycol bisglycidyl ether as crosslinking agent,Poly(γ-glutamic acid)/montmorillonite (γ-PGA/MMT) superabsorbent nanocomposite was prepared.The effects of crosslinking agent mass,MMT contents and reaction temperature on the saline water absorbency of the superabsorbent nanocomposites were studied.The experimental results demonstrated that the saline water absorbency of γ-PGA/MMT nanocomposites increased with the increasing of crosslinking agent mass firstly and decreased when the crosslinking agent mass was higher than 0.6g.The saline water absorbency of γ-PGA/MMT nanocomposites increased with the MMT contents up to 7% and decreased as the MMT contents further increased.Moreover,the saline water absorbency of γ-PGA/MMT nanocomposites increased with the reaction temperature firstly,and then decreased when the reaction temperature was higher than 50℃.
