Synthesis and Characterization of Carbon Nanotube Hydroxypropyl Methylcellulose Composites

Abstract

Abstract In tissue engineering especially, aqueous injectable, untouched gel- forming systems, possessing variety of advantages has been an attention seeker for the industry when compared to scaffolds. In-situ gel forming matrix can be introduced easily to the defect sites through needle, because of which surgical implantation can be removed first. Secondly, the ease of conformity upon introducing on the surroundings, and introducing easily on cells, and can be introduced as therapeutic agents and growth factors by simple mixing, without any afflict about residual solvents commonly used in scaffolds, when combined. For which, Multi-walled Carbon Nano-tubes has been acid functionalized which then covalently grafted on Hydroxypropyl methylcellulose (HPMC) by the Oxidized Carbon Nano-tubes, to form acylchlorinated carbon nano-tubes which has been firstly reacted with thionyl chloride and later dispersed in HPMC to form composite material, MWCNTs – HPMC, several time has been washed multitudinous to eliminate not reacted materials. FT-IR, TGA, SEM and TEM are used for the characterization of the composites, and which shows that it exhibits enhanced thermal stability.
