Abstract |
Poly(vinyl alcohol) (PVA) is a common hydrophilic polymer that is synthesized
through the saponification reaction of poly(vinyl ester)-based polymers, mostly
using poly(vinyl acetate) (PVAc) as a precursor. The heterogeneous saponification reaction
of poly(vinyl ester)-based films leads to PVA films with new surface properties.
Cellulose acetate (CA), in which the hydroxyl group of cellulose is replaced by an
acetyl group, is a typical cellulose derivative capable of overcoming the low processability
of cellulose due to strong hydrogen bonding. In this study, P(VAc/VPi)/CA
blended films were prepared by the solvent casting, and then PVA/Cellulose blended
films with improved surface properties were prepared by heterogeneous saponification.
The structural changes caused by heterogeneous saponification were confirmed by
FT-IR analysis, where both saponification and deacetylation reactions occurred in the
saponification solution. In addition, the surface property changes were analyzed by
FE-SEM and contact angle analyses, and the transmittance changes of the modified
films were also assessed. |
