CONDUCTIVITY PH-RESPONSIVE HYDROGEL USING CARBON NANOTUBE AND PROCESS FOR PREPARING THE SAME

摘要

PURPOSE: A pH-responsive conductive hydrogel is provided to achieve an effective drug delivery function with pH sensitivity and to ensure excellent contraction and relaxation. CONSTITUTION: A pH-responsive conductive hydrogel using carbon nanotube comprises the steps of: mixing polyvinylalcohol, pH-responsive vinyl monomer, cross-linking agent and solvent to prepare a hydrogel precursor solution; and adding drug-supported carbon nanotube and initiator to the hydrogel precursor solution; and drying the reactant after crosslinking to prepare a conductive hydrogel.
