Resumen:
Renewable resource based bylayer films were
prepared from polyhydroxybutyrate film (PHB) and cellulose cardboard
via compression moulding, containing 5, 10, 15 and 20 wt% of PHB.
The effects of PHB contents on moisture absorption, water absorption
and water vapor permeation of films were investigated. All
biocompiostes showed improved permeation properties. As of 15% of PHB,
water permeation, equilibrium moisture content and polarity showed a
marked drop. It is therefore assumed that the hydrophobic PHB covered
up the cellulose cardboard and formed a continuous layer. The
waterpolymer interactions in materials are critical to the prediction
of their behavior in applications where they are exposed to water or
humid environment.
