Investigation Of Polyvinyl Alcohol Added With Calcined Mussel Shell Biocomposite

This study is to investigate the characteristics of polyvinyl alcohol (PVOH) added with different amount of calcined mussel shell (HAp). HAp was extracted from the shell of Perna viridis through thermal calcination and followed by solution casting method to produce PVOH composite films, consisting 0...
