Learn more WhatsAppIn 1981, Diaz first synthesized Polythiophene (PTh). PTh is used as the electrode material of supercapacitor, mainly by modifying thiophene to make the corresponding electrode material. The mass Cs of the n-doped form is generally lower than that of the p-doped form. In general, the conductivity of the n-doped form is poor [133]. …
