Abstract
In order to prepare organic piezoelectric materials with good piezoelectric properties and enhance the intrinsic piezoelectric properties of the poly(vinylidene fluoride) (PVDF) crystal phase
a solution coating film-forming process was adopted to prepare PVDF films. The films with different stretch ratios (
R
= 3
5
7) were made by uniaxial stretch process. The morphology and structure of the films were investigated by scanning electron microscopy (SEM)
transform infrared spectroscopy (FTIR)
X-ray diffraction (XRD)
differential scanning calorimetry (DSC). Gold electrode is sprayed on the surface of the film and then the film is subjected to high-voltage electric field polarization treatment. Connect the films to the sampling multimeter to further study the piezoelectric properties of the films. It shows that uniaxial stretch can increase the crystallinity of PVDF and promote the transformation of
α
phase into
β
phase. During the stretch process
the molecular segments of PVDF are highly oriented to form the
β
phase of the all-
trans
conformational structure. The larger the stretch ratio
the higher the crystallinity of PVDF and the higher the relative content of the polar
β
phase. When the stretch ratio is 7
the relative content of
β
phase increases to 85.12%
which is 1.5 times higher than that of the unstretched film. Since the intrinsic piezoelectric properties of PVDF are controlled by its crystalline
β
phase content
the larger the stretch ratio
the better the ferroelectric and piezoelectric properties of the film. The film exhibits the best electrical properties when it is stretched 7 times: When the applied electric field is 200 MV/m
the residual polarization intensity reaches 2.69 μC/cm
2
. When the strain is 5%
the average output current density is 58.92 nA/cm
2
and the average output voltage is 89.70 mV. In this study
the single-axis stretched PVDF film has a high voltage sensing sensitivity
and a PVDF film in a small area size (22 mm × 4 mm) can provide an output voltage as high as 89.70 mV. Therefore
the material can be used to produce ultra-thin
lightweight portable electronic devices in ideal shape
and is expected to be used as a flexible touchable sensor to obtain biomechanical energy from the human body for health monitoring.
