composite polymer piezoelectric materials - Names and Identifiers
composite polymer piezoelectric materials - Introduction
Composite polymer piezoelectric material is a kind of material with piezoelectric effect, which is composed of polymer matrix and piezoelectric ceramic particles. Its properties include:
1. Piezoelectric effect: The composite polymer piezoelectric material can produce charge separation under the action of applied electric field or mechanical stress, resulting in charge accumulation and potential change.
2. Sensitivity: Composite polymer piezoelectric materials are very sensitive to changes in stress and electric field. Its piezoelectric coefficient is high, with excellent response speed and stability.
3. Mechanical properties: Composite polymer piezoelectric materials have excellent mechanical properties, with a certain degree of strength, elasticity and toughness.
Composite polymer piezoelectric materials are widely used in the following areas:
1. Pressure sensor: It can convert external pressure signals into electrical signals for pressure detection, acceleration measurement and other fields.
2. Sound wave generator: By changing the electric field or mechanical stress, the piezoelectric effect of the composite polymer piezoelectric material can be generated to generate sound waves.
3. Piezoelectric ceramic transducer: a device used to convert electrical energy into mechanical energy or mechanical energy into electrical energy.
The method for preparing composite polymer piezoelectric materials mainly includes the following steps:
1. Select polymer matrix: According to the required performance requirements and application scenarios, select suitable polymer materials as the matrix.
2. Addition of piezoelectric ceramic particles: Piezoelectric ceramic particles prepared in advance are added to the polymer matrix and uniformly mixed.
3. Molding processing: the mixed material is pressed, injection molded, calendering and other molding processes to prepare the required shape and size of the composite polymer piezoelectric material.
In terms of safety information, composite polymer piezoelectric materials are generally non-toxic and harmless, but the use of harmful substances may be involved in the processing process. When using and handling materials, care should be taken to comply with relevant safety procedures to avoid contact with hazardous substances or other safety hazards. In addition, during the use and maintenance of the product, care should be taken to avoid excessive voltage or force to prevent material damage or accidents.
