Development and Characterization of Polymeric Composites Reinforced with Lignocellulosic Wastes for Packaging Applications

In this work, the effects of different fiber loadings on mechanical properties composites at sub-micron scale were studied through nanoindentation followed by physical characterization. The prepared incorporating wheat straw, corn stalk, and rice husk in polypropylene copolymer using a melt processing method thermal–hydraulic compression technique. Nanoindentation experiments quasi-continuous stiffness mode performed surfaces produced to study composites’ elastic modulus, hardness, creep properties. obtained results expressed in-depth micro- macro-level structure behavior particle interactions. findings demonstrated that observable shifts rate had occurred. WS-reinforced biocomposite sheet showed highest modulus 1.09 hardness 0.11 GPa 40 wt% loading comparison other loadings. An impact strength 7.55 kJ/m2 was noted for RH loading. addition, optical microscopy, Fourier transform infrared spectroscopy, water absorption, thickness swelling, Vicat softening point studies conducted sheets evaluate differences physical, mechanical, thermal outstanding performance newly developed makes them suitable use as biodegradable packaging material.
