Ion implantation is one of the methods used to transform physical properties of polymers and to improve their electrical, optical, and mechanical performance. Ion implantation is a technique by which the ions of a material are accelerated in an electrical field and impacted into a materials such that ion are inserted into this material. This technique has many important uses. One such example is the introduction of silver plasma into the biomedical titanium. This is important because Titanium-based implantable devices such as joint prostheses, fracture fixation devices and dental implants, are important to human lives and improvement of the life quality of patients. However, biomedical titanium is lack of Osseo integration and antibacterium ability. Plasma immersion ion implantation (PIII) is a physical technique which can enhance the multi-functionality, mechanical and chemical properties as well as biological activities of artificial implants and biomedical devices. ERDA can be used to study this phenomenon very effectively. Moreover, many scientists have measured the evolution of electrical conductivity, optical transparency, corrosion resistance, and wear resistance of different polymers after irradiation by electron or low-energy light ions or high-energy heavy ions.
