Abstract

As-deposited poly(vinylidene fluoride) (PVDF) Langmuir-Blodgett (LB) nanofilms with a complete β phase show a remarkably high remanent polarization (Pr), about 6.6 μC cm-2 at 81 nm. Extrinsic switching characteristics of the nanofilms are demonstrated. Results also show that highly oriented PVDF homopolymer LB nanofilms down to 12 nm with no post-treatment retain robust room-temperature ferroelectric polarization switching that is greater than 105 operation cycles, with longer standing fatigue endurance than those of PVDF copolymer nanofilms.
