Polyaniline (PANI) is an electro-active polymer of great interest thanks to its outstanding physical and chemical properties whichmake it suitable for various applications in optics, bioelectronics, biosensors, diagnostics and therapeutic devices. Unfortunately, PANIis infusible and insoluble in most common solvents and, thus, very difficult to process. In the attempt of improving processability, yetpreserving its interesting properties, PANI has been synthesized in the form of particles and dispersed into a hydrogel matrix. The synthesisof PANI–hydrogel composites proceeds via c-irradiation of PANI dispersions as obtained by ‘in situ’ polymerization of aniline inthe presence of water-soluble, polymeric stabilizers. The chosen stabilizers are able to undergo to chemical cross-linking when exposed toionizing radiations, so forming the highly hydrophilic network that entrap PANI particles. The presence of a hydrogel matrix inducesbiocompatibility to the final composite material which, in a typical bottom-up approach, may become suitable for the development ofbiocompatible, optoelectronic devices. Some morphological and optical features of these novel soft, functional nano-composites are herepresented.
