Abstract
Electroactive P(VDF-CTFE) copolymers comprising CTFE in ranges between 5 mol % to 20 mol % are disclosed. The electroactive P(VDF-CTFE) copolymers are formed into films that exhibit strain values of 2% or more in response to one or more electromagnetic fields. The electroactive P(VDF-CTFE) copolymer films are deposited using ink-jet printing, slide coating, spin-coating, extrusion coating, meniscus coating, dip coating, spray coating or a combination thereof. Patterned P(VDF-CTFE) copolymer films are formed using lithographic techniques, nanoimprint techniques, nanolithography techniques or a combination thereof. The electroactive P(VDF-CTFE) copolymer films are used in the activation and/or operation of micro-mechanical devices and/or electrical devices.
