Product Description

PVDF PIEZO film with Cu-Ni

Polyvinylidene fluoride (PVDF) piezoelectric film is a new kind of polymer piezoelectric material which was developed in Japan in the 1970s. So far, only a few advanced countries in the world have produced it. It has unique dielectric effect, piezoelectric effect and thermoelectric effect. Compared with traditional piezoelectric materials, it has the advantages of wide frequency response, large dynamic range, high sensitivity of power-electric conversion, high mechanical strength, easy matching of acoustic impedance, light weight, soft and not brittle, impact resistance, not easily contaminated by water and chemicals, and easy to be made into pieces or tubes of different shapes and areas. It is widely used in mechanics, acoustics, optics, electronics, measurement, infrared, security alarm, medical care, military, traffic, information engineering, office automation, Marine development, geological exploration and other technical fields. It is a new type of energy exchanging material to produce improved pressure dynamic sensor, ultrasonic and intelligent detection.

PVDF piezoelectric film is a new kind of polymer piezoelectric energy exchanging material, which has unique dielectric effect, piezoelectric effect and thermoelectric effect. Compared with the traditional piezoelectric materials such as ceramics with wide frequency response, large dynamic range, power electricity conversion sensitivity is high, the mechanical properties of high strength, acoustic impedance matching characteristics, and have light weight, soft and crispy, impact resistance, not easily affected by the pollution of water and chemicals, easy to be made into any shape the advantages of the area range or tubular. It is widely used in mechanics, acoustics, optics, electronics, measurement, infrared, security alarm, medical care, military, traffic, information engineering, office automation, Marine development, geological exploration and other technical fields.

The standard sizes of cu-Ni PVDF piezoelectric films are 203*280mm and 0.4 m *1.0 m, and the thickness is 28 um, 52 um and 110 um.Sheet size options: 8" x 5.5" and 8" x 11"

The physical properties of the copper plating nickel PVDF piezoelectric film is excellent, with beautiful color, strong abrasion resistance has high chemical stability, excellent oxidation resistance and low moisture absorption, heat stability, high resistance to uv radiation, high impact resistance, fatigue resistance, its chemical stability more than 10 times the ceramic, under 80 ℃ can be use for a long time. PVDF piezoelectric film is soft in texture, light in weight, close to the acoustic impedance of water, good in matching state, and highly sensitive in application. PVDF piezoelectric film in the direction of thickness of the stretching vibration harmonic frequency is very high, can obtain a wide flat response, frequency response width is far better than ordinary piezoelectric ceramic transducer; High capacitance,

PVDF piezoelectric film has the following advantages:

(1) Good workmanship. Processing with existing equipment;
(2) It can produce large-area sensing elements;
(3) Frequency band response width (0 ~ 500MHz);
(4) The acoustic impedance is close to human tissues and water, so it can be used in the structure of sensitive devices for medical diagnosis;
(5) High impact strength (can be used in shock wave sensors);
(6) Corrosion resistance (this property is required when used in active media);
(7) Relatively low dielectric constant; The value of d33(about one order of magnitude higher than other piezoelectric materials) and the sensitivity of thermal signal (P /) are correspondingly higher.
(8) Compared with piezoelectric ceramics, it has lower thermal conductivity; And can make a thinner film;
(9) Soft and tough (PVDF's compliance coefficient is about 30 times that of PzT, and it is light (specific gravity is only about 1/4 of PzT); Can be made into a variety of required more complex shapes (cone, dome, etc.), can be used in the need for a special orientation of the elements.
In summary: PVDF piezoelectric film ratio quartz, PzT has the characteristics of large piezoelectric constant, wide frequency response, good mechanical strength, impact resistance, light weight, flexibility, easy to match sound impedance, easy to be processed into a large area, easy to be polluted by water and general chemicals, cheap price and so on. It can not only be used as a substitute for piezoelectric ceramics in many fields, but also can be used in situations where piezoelectric ceramics cannot be used. Therefore, it is a kind of energy - exchanging polymer sensitive material with a promising future
