New progress in water soluble conducting polymers

Water soluble conducting polymers of high resultant electrical conductivity are needed for use in typical high speed printing machines bit they have proved elusive. However, a research team in Louisiana State University has achieved this by attaching chains of a polyacrylimide derivative to polythiophene chains. The ink so created even has optoelectronic properties. It can change colour in reponse to stimuli so it could be used to print biosensors that detect specific analyte molecules or other parameters just as VTT technology of Finland uses printed polyanilene to detect time temperature excusions with both electrical and visual indication.
