Abstract
Next-generation soft X-ray missions, such as the Lynx X-ray observatory, are being proposed to increase the effective area of Chandra while keeping sub-arcsecond imaging resolution. Low-voltage thin-film actuators based on electroactive polymers can address the need for adjustable mirror control in future X-ray missions such as Lynx. Polymers can produce high strains at low voltages and correct the deformations that submillimeter-thick mirror shells will experience in future X-ray missions. Fabrication of polymer-based thin films is a low-cost, scalable technology that can easily be translated to production by industrial partners. With processing temperatures below 140oC, electroactive polymer films can be deposited on glass mirror substrates without risk of introducing additional slumping errors. We will present metrology results on prototype actuators based on micrometer-scale PVDF-TrFE polymer films deposited on glass substrates.
