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
