The morphology of the hydrolyzed MCC was investigated using scanning electron microscopy
(SEM), showing a compact structure and a rough surface. Furthermore, atomic force microscopy (AFM)
image of the surface indicates the presence of spherical features. X-ray diffraction (XRD) shows that the
MCC produced is a cellulose-I polymorph, with 87% crystallinity. The MCC obtained from OPEFB-pulp
is shown to have a good thermal stability. The potential for a range of applications such as green nano
biocomposites reinforced with this form of MCC and pharmaceutical tableting material is discussed
