Catalytic effect of rGO-CuO nanocomposite on performance of fire extinguishing aerosol forming composite

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] .
