Abstract
Cellulose nanosphere (CNS) was isolated from corn husk by delignification, bleaching, acid hydrolysis, dialysis, and sonication. Successful isolation of CNS was confirmed by FTIR Analysis. The isolated CNS was found to have an average diameter of 18 nm and crystallinity index of 70% using TEM and XRD Analysis, respectively. A decrease in onset degradation temperature (Tonset) and an increase in residual mass were also observed in the TG analysis of cellulose fiber and CNS. Nanocomposite hydrogels using poly (ethylene glycol) dimethacrylate (PEGDMA) as matrix and CNS as nanofiller was prepared by UV-curing. FTIR Analysis revealed similar transmittance patterns among all the treatments. Thermal characterization showed that the addition of CNS lowers the Tonset and Tmax while increasing the temperature required for the total degradation of the UV-cured nanocomposite hydrogels.
