摘要

全球社会面临的最重要挑战之一是精确测量和有效减缓二氧化碳排放,二氧化碳是造成全球变暖及其深远影响的主要因素。本文主要研究了用于CO2捕集的聚苯胺的合成和表征。通过在25-65℃的温度范围和1-9 bar的压力范围内进行实验,综合评价了这些聚合物的吸附行为。值得注意的是,在最佳条件下,聚苯胺的CO2吸附量为10.153 mmol/g。进一步的分析揭示了这些聚合物的循环稳定性,聚苯胺在第五次循环中表现出96%的吸附率。此外,我们还合成了这种聚合物的薄膜来评估它们的传感能力,聚苯胺薄膜对纯二氧化碳的响应率为51.35%。聚苯胺对不同CO2浓度表现出线性响应趋势。此外,薄膜传感器的最佳工作温度确定为35℃。该传感器的快速响应和恢复时间强调了其在实际二氧化碳传感应用中的潜在功效。总之,这些发现突出了聚苯胺作为二氧化碳吸附和传感的通用材料的良好性能,为开发可持续解决方案以应对紧迫的碳排放挑战提供了重要意义。

Evaluation of the sensing and adsorption performance of the synthesized emeraldine salt polyaniline for CO2 elimination

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 °C 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 °C. 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.
