FTIR and TGA analysis of biodegradable poly(lactic acid)/treated kenaf bast fibre: effect of plasticizers

A biodegradable composite (PLA/KBF blends) was prepared using melt blending technique in a brabender mixer and characterized with FTIR and TGA analyzer. Five percent of triacetin and glycerol contents were used as plasticizers to plasticise PLA matrix. KBF was treated with 4% NaOH solution, while...
