Abstract:
The effect of hexane treatment and uniaxial stretching in polyvinylidene fluoride
(PVDF) film was studied. The quantity, β31, defined as the bending piezoelectric
stress constant, was calculated. After hexane treatment and uniaxial stretching of
the PVDF film, the value of β31 was 5.75 mV/m and 8.00 mV/m for draw ratio of
1.5 and 2.5 was recorded. Fourier transform Infra-red (FTIR) spectrophotometry
was used for structural investigations.
