ABSTRACT
Received: 12/11/2020
Biodegradable
composite films, based on polyvinyl alcohol (PVA)
and lignin extracted from sugar bagasse, were fabricated with various
weight ratios between two components. The composites show
adequate characteristics contributed by
PVA and lignin which have
specific functional groups revealed by Infrared spectroscopy (FTIR).
In addition, the composites possess
outstanding characteristics
including comparable optical and mechanical properties investigated
by mechanical testing method and Ultraviolet–visible (UV)
spectroscopy. The results also reveal that the mechanical properties of
the PVA film containing 25% lignin are superior to the pristine PVA
film and the composite supplemented by lignin has the ability of high
absorbency of UV radiation, enabling the PVA/lignin composite film
to be used as an eco-friendly material with UV-shielding property.
