The effect of milling time on the microstructure of chitosan nanopowder had been
investigated. This study fabricated chitosan nanopowder via ball milling at different
milling time. The milling time used were 0, 60, 180 and 360 minutes, indicated by CHO,
CH60, CH180 and CH360, respectively. From the SEM results, the milling time not only
resulted in the homogenous dispersion but also the reduction of particle clustering and the
reduction of distances between the particles. The optimal grain and crystallite size of
CH180 is 8.5 nm and 20.1 nm, respectively. The chitosan nanopowder showed that the
milling time does affect the crystallite size. The average crystallite size of chitosan
nanopowder is 20 nm. The dielectric constant and loss values decrease with the frequency
and increase with the milling time. Thus, the effect of milling time on microstructures and
dielectric properties of chitosan nanopowder could increase the internal structure of the
granules and applied to synthesis the solid electrolyte.
