Polymer functionalized carbon nanotubes
Since the discovery of carbon nanotubes, there has been an intense effort to characterize and understand their properties and structural details, in order to enable their medical, electronic, and mechanical applications. Raman, near-IR, UV-Vis, and thermogravimetric analysis (TGA), have been employed to characterize carbon nanotubes to study the growth, functionalization, and electric and magnetic response of single wall carbon nanotubes (SWNTs).

Carbon nanotubes were functionalized along their side walls/end on with the polyurethane ionomers, acrylcates. An in-situ reaction, initiated by the production of free radicals upon the decomposition of peroxide during high temperature phase of processing, allows for the linkage of the carbon nanotubes to the surrounding acrylate matrix via covalent bond. The resulting polymerized functionalized carbon nanotubes were analyzed.




Raman spectra (633 nm) of (A) p-SWNT displays a small D-band, which is greatly increased in the products, (B) Functionalized-SWNT (Donna J. Nelson et al., J. Phys. Chem. C. 2007, 111 (48) 17872 17878).

Polymer clay nanocomposites
Montmorillonite (MMT) was modified by cationic exchange between MMT and different aromatic amines in an aqueous solution. A new nanocomposite consisting of polyurethane ionomers and functionalized MMT were interpenetrated with acrylic modified polyurethane to form interpenetrating polymer networks (IPNs). Polymer intercalated nanocomposites were shown in Figures.

Major Achivements
1) R&D (Technology developed to the Industries)
  • Development of water based super plasticizers from melamine formaldehyde sulfonamide resin for application in concrete admixture. This technology was successfully demonstrated by S. N. Jaisankar, T. Sivagamasundari, R. Ganesh Jeevan, and Ganga R. to M/s. Ultra tile Pvt. Ltd., Chennai.
Tiles developed from the superplasticizers

2) Ionic polymer liquid crystals: Synthesis, characterization and their thermoplastic blends [SERC-DST sponsored project, 2004-2007].
New Observations:
  • New class of different low molecular weight ionic liquid crystal poly(urethane-urea)s and functionalized diurethane liquid crystals were prepared successfully.
  • Al the liquid crystal poly(urethane-urea)s show the nematic mesophase.
  • Incorporation of ionic PUUs in TPU/SAN melt blends as a compatibilizers.
  • All the polymer melts exhibited non-Newtonian flow behaviour in the shear rate range studied.
  • The melt viscosity of the compatibilized blends did not show shear-thinning behavior, which could be due to small addition of ionic liquid crystalline PUUs.
  • The ionic liquid crystalline poly(urethane-urea), showed good compatibilizers for TPU/SAN melt blends.
