Elucidating the Influence of Cellulose Nanofiber on the Microstructure of Starch Nanocomposite Foams

In this research, starch nanocomposite foam reinforced by cellulose nanofiber (CNF) was prepared through freeze drying technique. The morphological results, obtained from SEM images, disclosed the formation of uniform cell distribution with small diameters in nanocomposite by adding CNF. Moreover, the mechanical analysis showed an improvement in modulus and compressive strength in composite reinforced by 20% of the CNF. The obtained bio-foam can be deemed as promising nanocomposite for developing highly porous foams in advanced bio-application
