1. An electrically-degradable polymer comprising:
polymer moieties comprising monomeric units, and a quinone moiety, which is a crosslinking agent between non-terminal monomeric units in the polymer moieties, and the quinone moiety has the formula: wherein R1, R2, R5, and R6 are selected from alkyl, aryl, alcohol, ether, thiol, thioether, amine, cyano, halo, nitro, ketone, aldehyde, ester, amide, thioester, carbonate, carbamate, and urea, R3 and R4 are selected from hydrogen, alkyl, aryl, alcohol, ether, thiol, thioether, amine, cyano, halo, nitro, ketone, aldehyde, ester, amide, thioester, carbonate, carbamate, and urea, X and Y is each attached to a polymer moiety and can be the same or different and are selected from vinyl sulfone, epoxide, alkyl halide, alkene, amine, alcohol, acid halide, acid anhydride, sulfate, phosphate, isocyanate, isothiocyanate, and thiol alkyl groups, wherein X and Y are released from the quinone moiety upon reduction of the quinone,such that the polymer moieties are capable of degrading from the quinone moiety the upon exposure to a change in electric potential. |
