Bilayer-structured humidity sensors based on quaternized and crosslinked poly(4-vinylpyridine)and polyaniline has been fac-ilely prepared. The electrical responses of the composite sensor towards humidity were measured. The effect of the concentration of polyaniline on its sensory properties was examined. Under optimal conditions,the composite sensor could detect very low humidity( down to ~1%RH)with good sensitivity(impedance increase of ~ 860% from 15% to 1%RH). Moreover,it exhibited fast response(t90%of 24 s and 35 s for adsorp-tion and desorption processes,respectively),small hysteresis( ~3%RH)and good repeatability.
