成果简介	NOVELTY - PANI (polyaniline)-PVA (polyvinyl alcohol) hydrogel based gas sensor comprises freeze thawed in-situ polymerized Polyaniline/Polyvinyl Alcohol (PANI/PVA) microstructure with enhanced pore size in the range of 2.36-3.42 nanometer diameter and surface area in the range of 39.48-78.12 meter sqaure/gram facilitating absorption and diffusion of gas molecule and sensor sensivity. USE - PANI (polyaniline)-PVA (polyvinyl alcohol) hydrogel based gas sensor. ADVANTAGE - The PANI (polyaniline)-PVA (polyvinyl alcohol) hydrogel based gas sensor improves crystallinity, morphology, surface area and hydrophilicity, absorption of water molecules, and hydrophilic gas sensing activity, exhibits high sensitivity to ammonia with a rapid response and recovery time of 10-25 seconds for real-time applications. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a process for fabrication of the PANI-PVA hydrogel based gas sensor, which involves: providing polyvinyl alcohol solution and adding aniline together with an oxidizing agent drop casted on a substrate followed by freeze thawing in cycles and obtaining therefrom repetitive freeze-thaw (FT) cycle promoted morphology of polyaniline/polyvinyl Alcohol (PANI/PVA) based conductive in-situ polymerized hydrogel adapted for desired gas sensing response.
