The piezoelectric property of PVDF cables is attributed to the structure of
PVDF, i.e. its beta phase content. The aim of this research was to optimiz
e the processing steps (e.g., electroding, coating) to maximize the beta ph
ase content in PVDF cables manufactured by the technology developed in the
Wroclaw Division of the Electrotechnical Institute (IEL). Microstructure ex
aminations were carried out on samples drawn at random from both semi-finis
hed and final products. The XRD examinations made it possible to assess the
effect of texture orientation, temperature and speed of processing operati
ons on the beta phase content in the PVDF. (C) 2001 Elsevier Science B.V. A
