Recently, it has been found that nonionic aliphatic and aromatic poly(ester sulfone)s show anode selective electrophoretic behavior, and it is shown that the electrophoresis is induced by a partial charge separation of the protic solvent at the dispersion interface. In this paper, the first example of temperature‐responsive electrophoretic deposition (EPD) is reported. Electrophoresis of a nonionic sulfone‐containing poly(N‐isopropylacrylamide) [poly(NIPAM)] is performed above the lower critical solution temperature. The poly(NIPAM) is prepared via reversible addition–fragmentation chain transfer radical copolymerization of NIPAM with a sulfone‐containing methacrylate. After EPD, adhesion of human umbilical vein endothelial cells on the deposited surfaces is also demonstrated, aiming at the subsequent temperature‐sensitive detachment.
