| Abstract: | The doped polyaniline with vanadium-titanium acid is synthesized by precipitation polymerization using ethanol as emulsion.The effects of synthesis conditions on polyaniline impedance property are discussed.The results show that under the conditions of temperature 0 ℃,the oxidation dosage 0.6 g,the molar ratio of vanadium titanium acid to aniline 2.3∶1,dipping one time and dipping 15 min,the impedance property of humidity sensor is better,and the impedance changes three orders of magnitude. |
