Evaluation of the sensing and adsorption performance of the synthesized emeraldine salt polyaniline for CO2 elimination
One of the paramount challenges confronting global communities is the precise measurement and effective mitigation of carbon dioxide (CO2) emissions, a primary contributor to global warming and its far-reaching impacts. This study focuses on the synthesis and characterization of polyaniline for CO2 capture applications. Through experimentation conducted within a temperature range of 25–65 and a pressure range of 1–9 bar, the adsorption behavior of these polymers was comprehensively evaluated. Notably, polyaniline exhibited an impressive CO2 adsorption capacity of 10.153 mmol/g under optimal conditions. Further analysis revealed the cyclic stability of these polymers, with polyaniline displaying a 96 % adsorption rate in the fifth cycle. Additionally, thin films of this polymer were synthesized to assess their sensing capabilities, with the thin polyaniline film exhibiting a 51.35 % response to pure CO2. Polyaniline demonstrated a linear response trend to varying CO2 concentrations. Moreover, the optimal operating temperatures for the thin film sensors were determined to be 35 . The rapid response and recovery times for this sensor underscore their potential efficacy in real-world CO2 sensing applications. In summary, the findings highlight the promising performance of polyaniline as a versatile material for CO2 adsorption and sensing, offering significant implications for the development of sustainable solutions to address the pressing challenges of carbon emissions.
