Abstract
ABSTRACTPolymeric-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 lightweight, flexible, biocompatible, etc. Proton radiation is a major form of ionizing radiation in space, particularly in the so-called inner Van Allen belt region where most near-earth satellites are orbiting, yet very few literature and data are available on proton radiation effects on conjugated polymer systems. In this report, the proton radiation effects on potential electronic/optoelectronic properties of several conjugated polymers and their composites are briefly evaluated. Specifically, UV–VIS absorption spectra of several conjugated polymers and/or their composite thin films were measured and compared right before and after the proton radiations at different dosages. The results revealed that proton radiation has very little or insignificant impact up to 800 rad on the optoelectronic properties of poly-3-hexyl-thiophene (P3HT), P3HT:PC60BM blend, a light harvesting donor-bridge-acceptor (DBA) and a novel donor-bridge-fluorinated-acceptor (DBfA)-type block copolymer thin films.
