Effect of nanoclay (NC) on mechanical and thermal properties of cellulose nanoparticles (CNPs) filled cornstarch bioplastic film

Abstract This paper explores the effect of nanoclay for improving interfacial properties starch bioplastic material filled with cellulose-nanoparticles (CNPs). The CNPs were prepared through acid-hydrolysis process by using acid concentration to break amorphous region chopped fiber produce nano-cellulose. Various (0.5 – 2.5 wt.%) dispersed in cornstarch biopolymer matrix form films solution casting method and listed thermal mechanical properties. Cornstarch 1.5 wt.% showed optimum improvement Furthermore, (NC) varying weight percentage (0.1 0.5 wt. %) added improved material. Hence, hybrid cellulose-nanoparticles/nanoclay (CNPs/NC) was both thermally mechanically. stiffness parameter ( $${\beta }_{f}$$ β f ) confinement $$C$$ C during relaxation stage 0.70 1.03 respectively fillers at 1.5/0.3_CNPs/NC, which is an indication that had a very good reinforcing on polymer system.
