AB  - A chitosan and guar protein isolate blend conjugate (Ch/GPI-Glu) based membrane has been designed and studied for its possible interaction with this biopolymer mixture. The designed conjugate chitosan/guar protein isolate blended membrane was investigated for its structural features using Fourier Transform Infrared Spectroscopy (FTIR), Thermal Gravimetric Analysis (TGA), X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) analyses. IR Spectroscopic data suggested that chitosan and guar protein isolate contributed to a specific intermolecular interaction. The designed membrane was water-insoluble and it exhibited strong polymer–protein interaction. Further, the membrane was also found to have a smooth morphology which was studied from the SEM morphological analysis. Thermo-gravimetric analysis suggested the enhanced thermal behavior of the membrane. This approach of introducing guar protein to chitosan structure imparts hydrophobicity with enhanced mechanical strength. Designing chitosan-based materials using such proteins opens a new field of research for researchers working in macromolecular chemistry. Further, this study also value-adds the structural features of guar protein isolate to study its possible interaction with other polysaccharides to get materials with tailor-made applications.
