Simple and facile technique of Chemical Vapor Deposition technique were employed to synthesize the multiwall carbon nanotubes, their morphology and characteristics were proven ability to deliver excellent mechanical, electrical properties and multi-functional properties for diverse applications. In order to delivering the benefits of technology, acidified and functionalized multiwall carbon nanotubes as an efficient reinforcement in terms of polymer nanocomposite. New comprehensive strategy of appropriate dispersion and good interfacial adhesion between the functionalized multiwall carbon nanotubes and Polymer matrix are desire able and addressed. Functionalized multiwall carbon nanotubes have been confirmed by using “Scanning Electron Microscopy (SEM)”, “Transmission Electron Microscopy (TEM)”, “Fourier Transform Infrared Spectroscopy (FTIR)”, and “Energy Dispersive X-Ray Spectroscopy (EDS)”. For effective and uniform dispersion of functionalized multiwall carbon nanotubes in Epoxy resin, various form of experimental strategies have been employed to achieve their maximum stability/strength and enhanced electrical properties. The engineering and adaptation of functionalized multiwall carbon nanotubes by epoxy provides not only excellent dispersion but also provide eminence interfacial adhesion. The mobility of the nanocomposite has been carried out by Hall analysis. The detailed investigation of electrical behavior of such nanocomposite also confirmed the insulative behavior of the matrix. It is expected that following product will contribute significantly in field of electronics sue to countless attractive features. •Epoxy/f-MWCNTs based nanocomposite was synthesized with 1 and 3 wt. %.•f-MWCNTs were confirmed with a set of detailed Morphological, Vibrational and Electrical characterization techniques.•Different types of the f-MWCNTs (1 and 3 wt. %) has been studied electrically.•Showing that when thickness of nanotubes decreases the sheet resistance of the nanocomposites also decreases and hence the mobility of the nanocomposites increases.•This may prove to be useful for the functionality of electrical devices based on these nanocomposite structures.
