Abstract: Polyaniline functionalized glass surfaces display excellent sensitivity and fast response to humidity. Functionalized glass surfaces were generated by first exposing hot glass surfaces to SOCl2 and aniline monomers and then by chemical polymerization of aniline on the surface. After making electrical contacts using platinum wires, another layer of polyaniline covering the contacts was generated by electrochemical polymerization. The sensor thus made displayed fast and reproducible response to humidity
