Synthesis and development of polyaniline-manganese dioxide composite thick films for acute detection of ethanol gas

Key Points

• Ethanol gas detection is achieved effectively using polyaniline-manganese dioxide composites, which show rapid response times.
• The composite thick films exhibit notable sensitivity and selectivity for ethanol, reaching detection limits well below harmful levels.
• Synthesis involves combining polyaniline with manganese dioxide to form thick films suitable for gas sensing applications.
• This technology highlights the potential for advanced sensing solutions in safety monitoring and environmental applications.
