| Summary: | In this study, nanocellulose is isolated from oil palm empty fruit bunches
using ultrafine grinding and ultrasonication. Here, nanocellulose, a
reinforcing agent, is mixed with polyvinyl alcohol and sodium alginate, which
act as the matrices. Nanocellulose-based fibers are produced via the wet
spinning method using calcium chloride as a coagulant solvent. The effects of
the nanocellulose content on the morphological, mechanical, and in vitro
biocompatibility properties of the produced fibers are then examined, with the
results demonstrating that the increase in nanocellulose content produces
fibers with a rougher cross-section and higher tensile strength with the
addition of nanocellulose up to 3%. Meanwhile, the crystallinity of the fibers
increases with the addition of nanocellulose content of up to 5%. The addition
of 1% nanocellulose produce fibers with better in vitro biocompatibility, which
is confirmed by the higher cell viability and lower inhibition. |
