We demonstrate a simple route to
versatile electrically addressable
conductive polymer graft copolymer systems. The monomer of poly(3,4-ethylenedioxythiophene),
one of the commercially most important conductive polymers, was modified
by the addition of an ATRP-initiating site to grow brushes from. The
modified monomer is easily accessible by a one-step synthesis from
the commercially available 2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)methanol. The modified monomer is subsequently
electropolymerized onto large area gold-coated electrodes and utilized
as a backbone for grafting pH-responsive poly(acrylic acid) brushes
from.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
