摘要

In this work, free-radical aqueous polymerization of acrylic acid (AAc) was carried-out in cellulose solution(dissolved in NaOH/urea system) followed by equilibration in ammonium sulfate solution to yield Regenerated Cellulose-Poly-acrylic acid (RC-PAAc) hydrogels.The water absorbency of these gels was investigated as a function of concentration of cellulose, acrylic acid and cross-linker N,Nmethylene bis-acrylamide. A negative concentration dependence of water uptake was observed. The gels were loaded with silver nitrate solution followed by borohydride reduction to yield silver nano particles loaded hydrogels. These gels were characterized by TGA, and TEM analysis. Finally the silver nano particles loaded gels demonstrated fair antibacterial activity against E.coli as model bacteria.
