ABSTRACT
Biocarbon (BC) has recently emerged as the biomass-derived filler for sustainable development of polymer nanocomposites. The concerned nanocomposites find their potential applications as heat resistant, electrically conducting coatings and in energy storage. Under the current pandemic scenario, the similar polymer-based coatings derived from carbonaceous fillers are also under trial for sustainable control over the propagation of the coronavirus. Industrialization and anthropogenic activities are continuously increasing the wastes on earth and simultaneously demand of energy in each sector of life. To resolve both of these, the present investigation deals with sustainable development of a series of polycarbonate (PC) based organic paint (OP) in the presence of pine cone- derived nano BC (0.95%) supplemented with talc (0.18 g), mica (0.50 g), silica (0.80 g), clay (1.50 g) and selected dyes. The OP was subsequently cast into thermally stable and electrically conductive films (ECF). A representative ECF derived from brilliant yellow dye (1 wt%) was characterized through Fourier transform infrared spectra, scanning electron microscopy, X-ray diffraction spectra, simultaneous thermogravimetric-differential thermal analysis-differential thermal gravimetric analysis and four probe DC conductivity measurements. The study reveals the nano structured nature of pine cone-derived BC and respective ECF. DC conductivity (σDC ×73.5 10-2 S/cm) of ECF was found independent on concentration of dye at 100V, 25±1°C. © 2022 Scrivener Publishing LLC.
