One）PVDFPiezoelectric film/PVDFThermoelectric filmbrief introduction：

PVDFPiezoelectric membrane is a new polymer piezoelectric energy exchange material，It has a unique dielectric effect、Piezoelectric effect、Thermoelectric effect。And traditional piezoelectric materials(Such as ceramics)Compared with the wide frequency response、Large dynamic range、High sensitivity of electro mechanical conversion、High mechanical strength、The acoustic impedance is easy to match，And it has light weight、Soft and not brittle、Impact resistance、It is not easy to be polluted by water and chemicals、It is easy to make any shape of sheet or tube with different area。In mechanics、acoustics、optics、Electronics、measure、infra-red、Security alarm、medical care、military、traffic、Information Engineering、office automation 、Marine development、Geological exploration and other technical fields are widely used。

Polyvinylidene fluoride（PVDF）Main products of piezoelectric filmThere is copper and nickel、silver、Three kinds of aluminum electrode materials，Film thickness28—500μm，Product shape、Area size，It can be determined according to the needs of users，It's making improved pressure dynamic sensors and ultrasound、New energy exchange materials for intelligent detection。

The film also has pyroelectric properties，It can produce a certain voltage output。

reminder：

（1）Our cut sample of piezoelectric film，Customers are required to wash the edges with high alcohol before use，Prevent short circuit。Because cutting may cause the positive and negative electrode layers to connect，Cause a short circuit。

（2）Our company can provide customers with PVDFPiezoelectric thin film sensor Conductive silver glue used，And sensor electrode wire（It can be provided free of charge6root！！）

（3）Piezoelectric film The sample does not support return service！ Please understand！！！

Characteristics of piezoelectric thin films:

Piezoelectric film is a kind of flexibility,Light weight,High toughness plastic film can be made into various thickness and large area。As a sensor，Its main characteristic parameters are as follows：

* Broadband: 0.001 Hz~1000M Hz

* Wide dynamic range（10 -8 ~10 6 Psi or μtorr~Mbar）

* Low acoustic impedance： With water、Human tissue is similar to viscose system

* High flexibility

* High voltage output: For the same stress condition，Higher than piezoelectric ceramics 10 times

*High dielectric strength: It can withstand strong electric field（75V/μm）Depolarization of most piezoelectric ceramics

* High mechanical strength and impact resistance（10 9 ~0 10 Pascal modulus)

* high stability : Moisture resistance（Hygroscopicity<0.02%） 、Most chemicals、Oxidant、 Strong ultraviolet and nuclear radiation

* It can be processed into specific shape

* Can be bonded with commercially available adhesive
