Ion Implantation of Polymers: Formation of Nanoparticulate Materials
The current paper presents a state-of-the-art review in the field of ion implantation of polymers. Numerous published studies of polymers modified by ion beams are analysed. General aspects of ion stopping, latent track formation and changes of structure and composition of organic materials are discussed. Related to that, the effects of radiothermolysis, degassing and carbonisation are consider...
متن کاملInfluence of nitrogen ion implantation on the nanostructure and corrosivity of Ni/stainless steel substrates
Ion implantation is a surface modification technology to produce new material on the surface by impingement of high energy ions from the ion accelerator. In this work, AISI 304 stainless steels were coated with 90 nm Ni film by electron beam deposition and implanted by a flow of 5×1017 N cm−2 at 400 K temperature with different implantation energies of 10, 20, 30 and 40 keV. The prepared sample...
متن کاملGraphene synthesis by ion implantation.
We demonstrate an ion implantation method for large-scale synthesis of high quality graphene films with controllable thickness. Thermally annealing polycrystalline nickel substrates that have been ion implanted with carbon atoms results in the surface growth of graphene films whose average thickness is controlled by implantation dose. The graphene film quality, as probed with Raman and electric...
متن کاملTransport System for Ion Implantation
ITEP in collaboration with MEPHI and HCEI (Tomsk) develops the high intensity ion beam generation and transport systems for low energy (1 – 50 keV) ion implantation. Such facilities are used for semiconductor technology. The Bernas type ion source is used for the ribbon ion beam production. The periodical system of electrostatic lenses (electrostatic undulator) was proposed for ribbon beam tran...
متن کاملBatch experimental studies of Hg(II) ion removal from aqueous solution using seven synthetic polymers
In this work application of seven synthetic polymers as adsorbents for the removal of Hg(II) from aqueous solution was studied. The equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and pH of the aqueous solution. Variations of Hg(II) concentration in solution have been studied through measur...
