Polymer brushes based on the conducting polymer polyaniline were synthesized on the interior of micro-capillaries
and micro-fluidic channels to study the influence of these brushes on solvent flow through a confined space. The
polyaniline brushes are formed using a grafting from approach . The optical/electrical proprieties of these
polyaniline coatings change in response to the pH of the solution that is flushed inside the micro-channel. These
unique proprieties offer a new route of characterising liquid transport in micro-fluidic devices and holds promise asa means for developing integrated micro-fluidic optical sensors.
