Abstract

The aim of this study was to investigate the feasibility of bacterial cellulose hydrogel (BC-g-PAA) as a nanoreactor to produce ferum oxide nanoparticles (FeNps). The bacterial cellulose hydrogel was synthesized by using free radical polymerization method. In general, free radical polymerization method is a type of chain polymerization (like ionic polymerization), where free radical monomer attacks double bond of another monomer to form bond and propagate the free radical. Ferum oxide nanoparticles (FeNps) were produced by incorporating 1×10-4g/mL ferrocenium salt (Fe+Cl-) into the hydrogel cellulose system and reduced using 1M concentration of sodium hydroxide (NaOH). The highest swelling ratio was observed at basic buffer solution (pH10). The FTIR analysis was also conducted to confirm the grafting of acrylic acid (AA) onto bacteria cellulose backbone. Hydrogel was characterized by using scanning electron microscopy (SEM) followed by energy dispersive X-ray spectroscopy (SEM-EDEX) to determine the iron (Fe) percentage. The resulting nanoparticles were extracted from hydrogel after calcination process, further analysed by using transmission electron microscopy (TEM) and X-ray diffraction analysis (XRD). Analysis TEM showed the diameter of particles ranges from 5-20 nm. XRD examination confirmed that the ferum oxide particles (Fe3O4) were located 2θ; 32°, 35°, 49° and 54°. The result demonstrate the feasibility of using bacterial cellulose hydrogel as promising as nanoreactor to produced ferum oxide nanoparticles (FeNps).
