Optimization of piezo-electric PVDF polymers for adaptive optics in space environments

Celina, Mathias C.; Dargaville, Tim R.; Martin, Jeffrey W.; Clough, Roger L.

The optimization of piezo-electric PVDF polymers for adaptive optics in space environments was discussed. The fundamental correlation between chemical and physical features of various PVDF copolymers and piezoelectric properties was analyzed. Using LEO solar ultraviolet data, total UV energy depositions were estimated as equivalent radiation doses with significant doses predicted for the thin films. A good retention of piezo properties during γ-irradiation was observed despite concurrent polymer damage with crosslinking and morphological changes.
