Abstract
A highly competent material, based on poly lactic acid (PLLA) grafted hydroxypropyl guar gum (HPG-g-PLLA) and polypyrrole/carboxylated multiwalled carbon nanotube (PPy/C-MWCNT) composite of various binary composition and copolymer of one of these nanocomposites have been synthesized successfully by in-situ polymerization. The environmentally affable nanocomposites have been characterized by spectroscopy, microscopy and thermogravimetry. Cytotoxicity of bio-nanocomposite has been inquired by cell viability study, which reveals its eco-friendly nature. The electrochemical properties of the biomaterials have been appraised by cyclic voltammetric studies. The PPy/C-MWCNT composite having 1 wt% C-MWCNT appears as the optimum composition from electrochemical studies. The hydrogel nanocomposite (HPG-g-PLLA5/0.5) copolymer behaves as a super ordinate material than pure PPy and PPy/C-MWCNT in every aspect of electrochemical properties like current density, stability, processibility and reversibility. Moreover the hydrogel nanocomposite, making electrode fabrication more simple and binder-free, nullifies all the interfacial complications arising from binders as well.
