Sa Shilpa, Venkatachalaiah, K. Nb, Damle, Rc, Kumar, Pd, Kanjilal, Dd, and Kumaraswamy, G. N., “Effect of low energy ion irradiation on the transport and structural behavior of PEDOT:PSS systems”, in AIP Conference Proceedings, 2016, vol. 1731.[Abstract]


In the past two decades, organic conductors have been widely explored for use in different applications. One of the extensively studied organic material for the use in the field of electronic devices is PEDOT:PSS. Organic/inorganic nanocomposite systems have been developed to improve the properties of organic materials. In the present study, we have made an attempt to understand the effect of low energy oxygen ion beam irradiation on the electrical and structural properties of PEDOT:PSS and PEDOT:PSS/TiO2 nanocomposites. The observed reduction in electrical properties in PEDOT:PSS systems may be linked to radiation induced phase change. The nanocomposite systems show better stability to the ion irradiation compared to the pure systems. © 2016 Author(s).
