synthesis of a novel PH-sensitive silver hydrogel nanocomposite based on poly acrylic amide grafted onto salep

in this paper a novel pH-responsive silver hydrogel nanocomposite based on poly acrylic amide grafted onto salep PAAm-g-salep were successfully prepared by in situ reducing Ag+ ions anchored in the hydrogel by the deprotonized carboxyl acid groups scanning electron microscope SEM TRANsmission electron microscopy TEM and thermo-gravimetric analyzer TG were used to characterize the nonocomposite system moreover compared to the pure PAAm-g-salep hydrogel not only did the Ag/PAAm-g-salep hydrogel nanocomposite exhibit much higher swelling ratioi and faster deswelling rate but also higher PH switchable electrical properties upon controlling the interparticle distance under PH stinulus
