Abstract

Polymeric thin film based electronic and optoelectronic materials and devices are attractive for potential space and certain radiation related applications due to their inherent features such as being light weight, flexible, biocompatible and environmental friendly, etc. Proton radiation is a major form of ionizing radiation in space, yet very few literature and data are available on proton radiation effects on conjugated polymer systems. In this study, UV-Vis absorption spectra of several conjugated polymers and/or their composite thin films were measured and compared right before and after a 200 MeV proton beam irradiation at different dosages, and the results revealed that proton radiation has very little or negligible impact up to 800 Rads on the optoelectronic properties of several polymers and their composite thin films.
