Thesis Title: Studies on Fullerene Containing Polymers: Synthesis and Characterization

Supervisor: Dr. Indira Nigam (Associate Professor, Plastic Technology, HBTI Kanpur)

Co- Supervisor: Dr. Dibyendu S. Bag (Scientist ?F?- Defense Materials & Stores Research &?Development Establishment)



Summary: Fullerene (C60) possesses a diverse range of unique properties such as electronic?and magnetic properties, optical non-linearity, photoconductivity, high mechanical strength

and thermal stability etc. However, the poor solubility of fullerene in many organic solvents

is a major drawback that has hampered the potential applications of fullerene in various?fields. This drawback is being overcome by incorporating fullerene (C60) into polymers. Thus??fullerene containing polymer materials? is a novel class of processable materials with?attractive properties for various applications. Hence fullerene containing polymers using?vinyl monomers such as methyl methacrylate (MMA), ethyl methacrylate (EMA) and n-butyl?methacrylate (BMA) were synthesized by free radical polymerization which is considered as

the easiest method for incorporating fullerene into polymers.



The kinetics of polymerization in the presence of fullerene was studied in details. These?fullerene containing polymers were characterized by FTIR, NMR, UV-Vis, GPC and TGA/DSC?analysis and studied for the thermal properties. The glass transition temperature (Tg)increases with increasing fullerene content because of bulky fullerene moiety which hinders?the segmental motion. The onset temperature of thermal degradation as well as charresidue was also increased with increasing fullerene content. Fullerene acts as radical?scavenger which resists the thermo-oxidative degradation of fullerene containing polymers.?TGA analysis was also used to determine the fullerene content in the polymers.



Cross-linked fullerene containing polymers of methyl methacrylate (MMA) and n-butyl?acrylate (BA) were also synthesized and studied for their thermal and water resistance?properties. The thermal stability and water resistance property of the polymers were

improved by incorporating fullerene into polymers. Fullerene acts as nanofillers when?incorporated into a cross-linked polymer matrix. Moreover, it is hydrophobic in nature.?Hence it obstructs the path of water permeation inside the polymer matrix thereby?improving the water resistance properties.



Fullerene containing hydrogels of poly (2-hydroxy ethyl methacrylate) were synthesized

and characterized for their gel swelling properties. Also fullerene containing thermoresponsive

smart hydrogels of poly (N-isopropylacrylamide) were synthesized and studied?for their swelling and thermo responsive behavior. The equilibrium swelling ratio is lower for?the fullerene containing hydrogels than that of the hydrogel without fullerene due to?hydrophobic nature of fullerene. Again it was decreased with increasing concentration of?fullerene into hydrogels. The swelling behavior of fullerene containing poly (HEMA)?hydrogels was found to follow Fickian behavior. However, incorporation of fullerene in the?cross-linked poly(N- isopropylacrylamide) hydrogel exhibits thermo responsive behavior with?slight decrease of the lower critical solution temperature (LCST).
