CAPACITORS AND CONDUCTING POLYMERS: DEVELOPMENT OF CONDUCTING POLYMER, INGREDIENTS AND THEIR CHEMISTRY

Abstract

Together with rapid progress achieved by the electronics industries, electrolytic capacitors for electronic circuits have been miniaturized and are now being manufactured by automated production facilities. Also demand for them is being diversified. Various organic ammonium compounds are used to meet these production trends for electrolytic capacitors and to replace conventional conducting polymer. To improve the performance of polymer electrolytes, it is necessary to improve their electrical conductivity, boiling points, setting point, viscosity and their anode and cathode corrosion inhibition characteristics. Basically capacitor is a device which can able to store the charge when potential is applied and able to provide energy whenever require in circuit. There are various kind of capacitors such as mica, ceramic, paper, gold, tantalum capacitor in which conducting polymer play vital role. Aluminum electrolytic capacitors are more popular than others due to wide range of capacitance i.e from 0.1 micro Farad to 3,30,000 micro Farad in 6.3Wv to 451Wv design is possible with longer life in low cost. Capacitor are normally used to filter the current and commonly used in Television, Radio, Switching power supplies, Computer and in photoflash applications in cameras.
