A facile synthesis of rGO-CuO nanocomposite was carried out using hydrothermal method. rGO-CuO nanocomposite was incorporated in aerosol forming composite (AFC) for the first time in order to develop the fast fire extinguishant materials. Synthesized nanocomposites were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy (SEM), energy dispersive Xray spectroscopy (EDX) and transmission electron microscopy (TEM). Catalytic activity of rGO-CuO was analysed considering the parameters such as combustion temperature, activation energy, burn rate, combustion efficiency, minimum fire extinguishing concentration (MEC) and fire extinguishing time. Addition of rGO-CuO to base AFC remarkably enhanced the performance of AFC by increasing the combustion efficiency (11.36) and decreasing the combustion temperature (16.14) and MEC (19.78). A tremendous increase in burn rate (47.1) boosted the fast extinguishment of fire by reducing the fire extinguishment time 78.2. Developed AFC found promising to meet the faster fire extinguishment requirement of futuristic fire suppression systems. GRAPHICS .
