AREA OF RESEARCH:

  • Inorganic-organic hybrid nanocomposite thin film/coatings on different substrates (plastic, glass, metal, ceramic and allied materials etc.) by sol-gel processing
  • Anti-scratch and antireflection coatings on plastics
  • Metal nanoparticle doped coloured coatings on glass and plastic substrates for optical non-linear and solar glass applications
  • Hydrophobic/superhydrophobic coatings on glass, plastic, metals and ceramic substrates, ordered mesoporous coatings.
  • Corrosion resistant hydrophobic coatings on metals.
  • Functional dense thin electrolyte using wet chemical method for SOFC application.

The characterization of above nanocomposite film materials was done using UV-visible

and FTIR spectroscopy, Grazing incidence X-ray diffraction (GIXRD), ellipsometry, Scanning electron microscopy (SEM), Field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM), Raman, Contact angle measurement etc.

 

RESEARCH INTEREST:

Research and development of scratch resistant hard and AR coatings on plastic substrates, hydrophobic/superhydrophobic coatings on glass, plastic, ceramic and metal substrates, and metal doped optical coatings for solar glass applications. nanocomposite dielectric thin films, ordered mesoporous coatings, coloured coatings, conductive coatings. semiconductor nanoparticles, nonlinear optical materials, nanocomposite materials for optical and electronic, SOFC device applications, polymeric membrane for combating antimicrobial resistance in medical implant infections, proton transfer cellulosic ion exchange membrane in redox flow battery etc, room temperature curable hydrophobic/superhydrophobic cum antibacterial coatings on glass, ceramic tiles and metal substrates.

 

Notable Research Contribution and Achievements:

¨ Developed scratch resistant coatings on polycarbonate sheets of dimensions 2 feet x 2 feet using conveyorized 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 according to international standards. Another advantage of the coating is that it increases by about 3% transmission compared to the uncoated polycarbonate. This is due to the lower 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

¨ Developed antireflective coatings on plastic sheets and ophthalmic lenses.

¨ Developed hard coatings on PP and PET and refractive index-controlled coatings on plastics.

¨ Developed hard and hydrophobic/ superhydrophobic coatings on glass plastic and related substrates.

¨ Refractive index (1.48-1.65) controlled coatings on plastics for scratch healing purposes.

¨ Corrosion resistant hard and hydrophobic coatings on metals (mild steel and aluminum).

¨ 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.

¨ Room temperature curable hydrophobic coatings on glass, metal and tile substrates.

¨ Developed room temperature curable insitu generated stable silver nanoparticles embedded hybrid nanocomposite coatings on glass substrates towards enhanced weather resistance properties and its antibacterial applications.

 

  • Technology transferred to the industry:

First company (AST) has already started their production since 2005. They have the capacity of coating deposition 1000 pieces of lens per day. Demand potential of this coated lens in the Indian market is very high.

This process has also been transferred to M/s Kumar polylenses, Mohali, 2004. They did not start production due to their own problem.

An antireflective (AR) coating on plastic, RSW glass substrates is also ready for transfer.
