Using the Advanced Analytical Techniques to Investigating the Versatile Cellulosic Graft copolymers

Ashish Chauhan and Balbir Kaith

In this research paper, the cellulose rich biomass of Sorrel was graft copolymerized by vinyl monomeric mixtures. The graft copolymers were characterized by advanced analytical techniques like FTIR, SEM, XRD, TGA and DTA techniques and evaluated for physico-chemical changes in the properties of the modified fiber. With increase in the percentage grafting a significant physico-chemico-thermal resistance were observed. Miscibility in organic solvents, hydrophobicity were found to increase whereas crystallinity, crystallinity index, dye-uptake and hydrophylicity decreased after graft copolymerization, however, the cellulose form I remained unchanged. These graft copolymers were then used as reinforcement in phenol-formaldehyde polymer matrix based green composite. They were then characterized and evaluated for their physico-chemico-thermo-mechanical competence. The use of graft copolymers as reinforcement in polymer matrix is the best technique to procure green composite. The novelty of the work lies in the use of renewable waste biomass to procure the advanced material. These advanced materials could serve as pioneer for scientific and industrial applications.
