Abstract
The objective of this work was to prepare functionalized cellulose fiber from sugar cane leaf (SCF) used to produce novel biomaterial. The SCF was treated with chloroacetic acid and sodium hydroxide (NaOH) to produce a modified cellulose fibre (MSCF). At higher MSCF loading, a greater porous density was observed under SEM. The addition of MSCF improved, the water resistance of the cured PVA/MSCF in both acid and base media through chemical reactions. The moisture absorption and moisture content of the cured PVA/MSCF film increased as the loading increased MSCF. Tg of the cured PVA/MSCF showed a clear decrease that was attributed to the greater molecular weight and softness of the molecular chains. The cured PVA/MSCF showed good MB absorption from wastewater. The improvement in biodegradability of the cured PVA/MSCF film may make it a candidate material for use in environmentally-sensitive applications.
