ABSTRAKTujuan kajian ini adalah untuk mengkaji kebolehan hidrogel daripada selulosa bakteria (BC-g-PAA) sebagai pembawa bagi menghasilkan nanozarah ferum oksida (FeNps) SB). Imej hidrogel telah dicirikan melalui analisis mikroskopi elektron imbasan (SEM), diikuti oleh spektroskopi tenaga serakan X-ray (SEM-EDX) dalam penentuan peratusan elemen ferum (Fe). Nanozarah berhasil diperolah selepas hidrogel dikalsinkan, seterusnya zarah tersebut diuji melalui mikroskopi transmisi elektron (TEM) dan pembelauan sinar-X (XRD

Abstract. This study focuses on hydrogel as nano template to produce iron nanoparticles (FeNps). Radical polymerization was used to synthesize the hydrogel from nata de coco (NDC-g-PAA). Ferrocenium (FcCL) with 1 x 10 -4 g/ml has successfully incorporated with NDC-g-PAA hydrogel system and reduce using sodium hydroxide (NaOH) at different concentrations. Transmission electron microscopy (TEM) result demonstrates that the size of FeNps produced was about 5 -20 nm. Morphological analysis of hydrogel is carried out by scanning electron microscopy (SEM), SEM-EDEX is used to determine percentage of iron (Fe) in hydrogel. The results offer a wide range of application in various areas, especially the use of hydrogel system as a responsive template.
