Abstract
Provided is a method for electrochemical preparation of polythioctic acid (PTA) and a derivative thereof. The method includes: mixing a thioctic acid (TA) monomer, a supporting electrolyte, and a polar solvent to obtain a mixed liquor; and subjecting the mixed liquor to electrochemical polymerization to obtain the PTA and/or the derivative thereof on a surface of an anode, wherein the TA monomer comprises one or more selected from the group consisting of TA and a TA derivative, and the TA derivative has a structure shown in formula I, wherein R is a derived group.
