• Biopolymers have paramount importance in pharmaceutical applications and blended biopolymers have shown promising properties versus individual counterparts. In view of excellent performance of blended biopolymers, a novel series of blended membranes based on chitosan, guar gum and polyvinyl alcohol (CS/GG/PVA) were prepared by solution casting technique. The membranes were synthesized at different ratios of GG and CS, while keeping PVA constant. The surface morphology, structure, interaction of polymers and water absorbing capacity were determined with scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and swelling properties. FTIR exhibited intermolecular bonding between the biopolymers used for membranes preparation. SEM analysis revealed that the surface morphology depends upon the various ratios of polymers. The swelling pattern has shown that the prepared membranes were hydrophilic in nature. Results revealed that the chitosan and guar gum based ternary blends with polyvinyl alcohol have potential for controlled drug release. •Ternary blended membranes based on guar gum, PVA and chitosan were prepared.•Solution casting method was used for fabricated of membranes.•Morphology, structure and water absorption capacity were studied.•Blends have potential for drug delivery and water purification.
