SYNTHESIS AND CHARACTERIZATION OF N-[3-(DIMETHYL-AMINO)PROPYL]METHACRYLAMIDE/(NANO-SiO2, AMINE-MODIFIED NANO-SiO2 AND EXPANDED PERLITE) NANOCOMPOSITE HYDROGELS

Fatma Özge Gökmen, Nursel Pekel Bayramgil.




Abstract

The nanocomposite hydrogel of N-[3-(dimethylamino)propyl]methacrylamide (DMAPMAAm) with different SiO2 particles were prepared by free radical polymerization. The nano-SiO2 as reinforcement material was used in original, hydrophilic and perlite forms. The swelling values of nanocomposite hydrogels containing amine-modified nano-SiO2 were found to be higher than those of the original DMAPMAAm hydrogel and the nanocomposite hydrogel containing original SiO2. SEM and mapping studies with SEM proved the presence of nano-SiO2particles incorporated into the hydrogel structure.

Key words: Nanocomposite hydrogels, nano-SiO2, biocompatibility, SEM-mapping, N-[3-(dimethylamino)propyl]methacrylamide (DMAPMAAm).
