Abstract: Well-organized and stable silver nanoparticles (AgNPs) were successfully prepared within polymeric film of polyvinyl alcohol and Polyvinylpyrrolidone as supporting matrix. The free-standing film was obtained by using the casting technique. Electron microscopy techniques confirmed the… read more here.

DOI: 10.1039/c8nj02132e
Abstract: In this paper, poly(N-isopropylacrylamide) (PNIPPAm), polyacrylic acid (PAA), polyvinyl alcohol (PVA) and cellulose nanocrystals (CNC) were used to prepare double-network hydrogels by the photo-crosslinking technology. The results from mechanical and swelling tests indicated that photo-crosslinked… read more here.
