| Summary: | From the environmental point of view, biodegradable materials have been rapidly
developed in the past years. PVA is one of the biodegradable synthetic polymers commonly
used, but its degradation rate is slow. As an alternative to reduce plastic waste and accelerate
the degradation process, PVA frequently blended with other natural polymers to improve its
biodegradability. The natural polymer such as starch has high potential in enhancing PVA
biodegradability by blending both components. The usage of starch extracted from agriculture
wastes such as jackfruit seed is quite promising. In this study, jackfruit seed starch (JFSS)/poly
(vinyl alcohol) (PVA) blend films were prepared using the solution casting method. The effect
of starch content on the mechanical (tensile strength and elongation to break %) and physical
properties of the tested films were investigated. The optimum tensile strength was obtained at
10.45 MPa when 4 wt. % of starch added to the blend. But, decreasing trend of tensile strength
was found upon increasing the amount of starch beyond 4 wt. % in starch/PVA blend films.
Nevertheless, elongation at break decreases with the increase in starch content. The mechanical
properties of the blend films are supported by the Field Emission Scanning Electron
Microscopy (FESEM), in which the native JFSS granules are wetted by PVA continuous phase
with good dispersion and less agglomeration. The incorporation of JFSS in PVA has also
resulted in the appearance of hydrogen bond peak, which evidenced by Fourier Transform
Infrared (FTIR). Additionally, the biodegradation rate of JFSS/PVA was evaluated through soil
burial test |
