聚苯胺是一种导电聚合物，其中氧化还原和质子化/去质子化传导机制在气态化合物存在下被激活，使其成为气体传感器。特别是基于聚苯胺的电阻化学传感器，其气体传感特性已得到充分研究，并且由于它们在室温下工作，因此被认为是具有广泛应用的重要传感材料。然而，有一类新型聚苯胺与醋酸纤维素的混合物，可能适合检测皮肤散发的生物标志物，并测量疾病的呼吸冷凝液的 pH 值，因此值得进一步研究。
Polyaniline is a conducting polymer in which both redox and protonating/deprotonating conduction mechanisms are activated in the presence of gaseous compounds, making it a gas sensor. Resistive chemosensors based on PANI, in particular, have been well studied for their gas sensing properties and are considered important sensing materials for a wide range of applications as they operate at room temperature. There is, however, a novel class of polyaniline hybrids with cellulose acetate that may be suitable for detecting biomarkers emitted from the skin and in measuring the pH of breath condensate for diseases and thus, worth studying them further.
