Polymers have wide range of applications in all human activities. Recent policies on environment and resource efficient mean that new efficient production and engineering processes need developing. This paper presents a new approach of laser irradiation of polymer aiming at inducing specific conductivity properties. Under the influence of a CO2 laser irradiation of polymers in the air, new macromolecular chemical and physical structures were engendered, which have electrical conductivity and paramagnetic properties. The conductivity of these substances are due to formation of carbon chains with conjugated double bonds and paramagnetic centres due to free radicals and charges localized around the structural defects near the surfaces of polymer sheet. The results show the formation of electrical conducting channels with desirable configuration in very short time without high vacuum, which can be used for production of printed circuits. This isn't achievable by high temperature treatment of polymers in room environment
