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. |
