| Summary: | Synthetic plastics pose one of the biggest threats to the environment and a promising solution is biodegradable
polymers. This study investigates the properties of biofilms prepared using starch/keratin blend with and without formaldehyde.
Some starch properties in percentage are; moisture content 0.27, hydration capacity 189.66, amylopectin content
65.79 and amylose content 34.21. From the water testing results, thickness swelling, water absorption capacity and linear
expansion of biofilm without formaldehyde after 10 s of soaking in water were 28.59%, 8.89% and 4.90% respectively and
65.30%, 91.33% and 46.29% respectively after 40 s. But, higher values are recorded for those biofilms made with addition of
formaldehyde. Thus using water effect on the properties of the biofilms as the performance index, the research indicates that
biofilms without formaldehyde had better performance than those with formaldehyde
