Research Interest

Research and development of scratch resistant hard and AR coatings on plastic substrates, hydrophobic/superhydrophobic coatings on glass, plastic and metals, and metal doped optical coatings for solar glass applications. Optical, electrical and magnetic properties of nanocomposites. nanocomposite dielectric thin films, ordered mesoporous coatings coloured coatings, conductive coatings. semiconductor nanoparticles, nonlinear optical materials, Thermoelectric generator and devices, and nanocomposite materials for optical and electronic device applications.

 

Landmark Research Contribution

  • Developed scratch resistant coatings on polycarbonate sheets of dimensions 2 feet x 2 feet using conveyorised UV curing machine. The hardness of the coatings is of the order of 5H. Both the adhesion and abrasion resistance properties of the coatings have passed following international standards. Another advantage of the coating is that it increases about 3% transmission compared to the uncoated polycarbonate. This is due to the low index of refraction of the coating material than that of polycarbonate.
  • ¨ Developed thermal curable (90-100°C) hard coatings on CR-39 grade plastics ophthalmic lenses.
  • ¨ Developed coloured coatings on Soda glass, PC sheets and CR-39 lenses
  • ¨ Development of antireflective coatings on plastic substrates.
  • ¨ Developed hard coatings on PP and PET and refractive index controlled coatings on plastics.
  • ¨ Developed of hard and hydrophobic/superhydrophobic coatings on glass plastic and related substrates.
  • ¨ Refractive index (1.48-1.65) controlled coatings on plastics for scratch healing purpose.
  • ¨ Corrosion resistant hard and hydrophobic coatings on metals (mild steel and aluminium).
  • ¨ Developed Antireflective (AR) cum hydrophobic coatings composition for ordered mesoporous silica on textured solar cover glasses to increase photo-current with easy maintenance
  • ¨ Developed reflection coatings on glass substrates.
  • ¨ Developed Antireflective (AR) cum hydrophobic with gamma resistant coatings on stabilized RSW glasses.
  • MRSI ‘Young Scientist’ award, (Kolkata Chapter, 2005).
  • NRDC ‘Meritorious Invention Award’ 2007 jointly with Dr. Goutam De for the invention of “anti-scratch coatings on plastic ophthalmic lenses and sheets using inorganic-organic hybrid nanocomposites”.
  • Ganpule Award-2022 for contribution in the field of white-ware, tiles, sanitary-wares & related subjects for the paper entitled “Photocatalytic evaluation of anatase TiO2 coating on ceramic tiles by Raman spectroscopy” by S. K. Medda, S. Manna and G. De published in the Ind. Ceram. Soc., 2020, 79 (1), 13-17.
