In this work, we prepared hydrogels based on PVA, CHI and Gr, and used them
as a porous matrix to synthesize silver nanoparticles by an in situ electrochemical
method [3,4]. The hydrogels were prepared from PVA/CHI/Gr colloid dispersions
using a simple and effective freezing-thawing method for gelation, without the use
of chemical cross linkers. The hydrogels were then swollen in AgNO3 solution to
saturate with Ag+ ions and subsequently subjected to constant-voltage electrical
current, to reduce silver ions and to obtain AgNPs. This electrochemical method
is fast and green, as there is no need for the use of any (potentially toxic) chemical
cross linkers and reducing agents, rendering the final product non-toxic and safe for
medical applications.
