    Description of Research Work

  1. Earlier research work:
    • Physico-chemical properties of water-soluble monomers/ oligomers/polymers in aqueous and non-aqueous media and blend compatibility using solution, thermal, microscopic and spectroscopic techniques
    • Developed different polymer carriers in the form of nano/micro/bead/gels using bio and synthetic polymers for drug delivery applications
    • Development and characterization of nano-composite, blend and zeolites filled polymeric membranes for pervaporation separation applications.
    • Bulk-heterojunction polymer solar cells based on donor-acceptor system of conjugated polymers and C60 derivatives and afrbaication of polymer light emitting diodes.
  2. Current research activities:
    • Metal/polymer nanocarriers for drug delivery applications Bio-synthesis of silver and copper nanoparticles by using different plant and millet extracts whereas polymer based nanoparticles are being developed by using newly developed methods. Different anit-cancer drugs are loaded into polymer nanocarriers and their release characteristics are being measured. We are trying to develop a versatile method by which one can control many parameters.
    • Polymer based blend/nanocomposite membranes: Development of blend membranes based on poly (vinyl alcohol), hydrophilic polymer blending with small amounts of hydrophobic poly(acrylonitrile), Poly(styrene), Poly(methyl methacrylate). Chitosan/sodium alginate based nanocomposite membranes are being fabricated by incorporating different amounts of TiO2 nanostructures such as particles and rods are into the polymer matrices. These membranes are being used for pervaporation separation of water-organic mixtures.
  3. Future research plans: In continuing the current work, I am planning to establish photovoltaic fabrication lab to develop polymer/organic based materials for solar harvesting applications.
