Abstract: Electrically conducting composite particles were manufactured consisting of a morphine-imprinted methacrylic acid-ethyleneglycoldimethacrylate copolymer interpenetrated with a polypyrrole network. The imprinted polymer was first prepared and then used as a host polymer into which pyrrole monomer was adsorbed. After partial drying of the pyrrole-saturated host polymer, an oxidant was adsorbed, whence polymerization took place. The resulting composite was found to have retained its molecular recognition properties and obtained electrical conductivity. Characterization of the composite particles was performed by scanning electron microscopy, energy-dispersive X-ray analysis, pore volume and surface area measurements and elemental analysis. Potential applications of these composite polymers, especially in sensor technology, are discussed
