| Abstract: | Direct deposition of high quality ferroelectric PVDF thin films using a modulated temperature spin coating method is demonstrated. The method is qualitatively guided from Flory‐Huggins theory of polymeric solutions and is general in applicability. Ferroelectric PVDF films with similar high structural and dielectric quality are deposited in environments ranging from 20 to 80% relative humidity on polar and non‐polar surfaces. The films do not show the presence of the non‐ferroelectric α‐phase. Resultant films have rms roughness values lower than 16 nm and remnant polarizations up to 6.5 µC cm?2. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym. Phys. 2017 , 55 , 221–227 |
