Abstract
A piezoelectric medical device and a process for preparing the same by electrostatically spinning a copolymer of vinylidene fluoride and a second fluorinated hydrocarbon, and collecting the spun fibers on a suitable receiver is disclosed.
Claims9
A process for preparing a biomedical device exhibiting piezoelectrically comprising the steps of electrostatically spinning fibers of a copolymer of the following:
- a) a predominant amount of vinylidene fluoride, and
- b) a second fluorinated hydrocarbon, selected from the group consisting of trifluoroethylene and tetrafluoroethylene, under conditions suitable for the formation of piezoelectric fibers;
- and collecting the spun fibers on a suitable receiver.
