Natural cellulosic/lignin resources offer a variety of applications in the fields of biomedical, automobile, and food packaging. Grafted copolymerization of renewable resources is used to develop composite materials based on biopolymers and natural fibers. Generally, grafted copolymers improve interface adhesion between the fiber and matrices and enhance the mechanical and thermal properties of composites. This article report on various grafting reactions for modifying the properties of biopolymers, the influence of reaction parameters such as the initiator molar ratio, the reaction time and temperature, the monomer concentration, the solvent value on optimized (50%–92%) grafting, and so on. The effect of the grating percentage on the physicochemical properties and characteristics of different grafted copolymer bio-composites were studied by X-ray diffraction and Fourier transform infrared and scanning electron microscopy.
