The polypyrrole prepared with pyrrole monomer, APS and DBSA was synthesized by chemical Polymerization at V ? C under atmosphere conditions. After dissolving polypyrrole powder to the chloroform including DBSA, polypyrrole film was prepared on the alumina substrate with an interdigitated electrode by using the dip-coating method. This film was soaked in methanol solvent for 1 h at room temperature and heated to 70 ? C for 4 h in N 2 . Initial resistance was increased with the increasing humidity and decreasing temperature. The sensitivity was increased with lower humidity and decreasing temperature. The best linearity was achieved at 25 ? C and low humidity of 0%.

Keywords:polypyrrole gas sensor;humidity effect;absorption site
