This mini-review examines the potential of polyaniline (PANI) composites in hydrogen sensing applications, emphasizing the mechanisms underlying PANI-hydrogen interactions. It highlights the properties and synthesis methods of different nanostructured pure PANI, PANI-carbon-based composites, and PANI-metal oxide-based composites, emphasizing approaches and PANI’s hydrogen sensing performance. The review explores the electrical and morphological properties of PANI and different hybrid materials’ nanocomposites, focusing on their enhanced sensitivity in hydrogen detection. Additionally, it addresses challenges such as poor solubility and low thermal stability, while outlining future research directions to advance this critical field.
