Conducting polymers are novel organic materials that have both electrical and optical properties similar to inorganic semiconductors. Due to the fact that some tissues are responsive to electrical stimuli, recently, some of the conducting polymers have been studied for biological engineering. However, very a few studies have been conducted in use of aniline-based polymers. Poly(aniline) has very limited choice of solvents and un-modified polymer is water-insoluble. We synthesized oligomeric aniline tethered with an ethylene glycol (EG) block which assisted the polymer for solubilizing in water. Therefore, we successfully fabricated thin films of this tetraaniline(TA)-block-EG-copolymer with poly(acrylic acid) on indium-tin oxide (ITO) substrates by layer-by-layer process. The deposited films appeared highly uniform and optically clear. We measured the optical, electrical and surface properties of the multilayer films. Cellular interactions on these multilayer coatings were studied. |
