n the present work, we report our research on cellulose nanofibers decorated with silver nanoparticles by novel
methods. Cellulose acetate was used as a precursor for cellulose nanofibers. Cellulose acetate nanofibers were
fabricated by electrospinning and then treated with 0.01 M NaOH solution for 30 hours to produce cellulose nanofibers.
Synthesis of silver nanoparticles was carried out by three simple methods. AgNO
3
was used as precursor for synthesis
of silver nanoparticles. Three methods were used for reduction of ionic silver (Ag
+
) into AgNPs were heat treatment,
N, N-Dimethylformamide induced heat treatment and 3,4-Dihydroxyphenethylamine coating. The samples were
characterized by scanning electron microscopy (SEM), X-ray diffraction spectroscopy (XRD), transmission electron
microscopy (TEM), Fourrier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and
Field emission scanning electron microscopy (FESEM). Sizes of the AgNPs were calculated using Debye-Scherrer
method and from the TEM images. SEM and FESEM images depicted regular morphology of the nanofibers. Structural
modifications of cellulose acetate into cellulose were confirmed by FTIR and XRD analysis. Formation of the metallic
silver was confirmed from XRD and XPS data. XRD data revealed FCC crystalline structure of the AgNPs. TEM images
show cellulose nanofibers covered with well dispersed AgNPs.
