Background technology
Piezoceramic-polymer composite material is a kind of new material consisted of combination process piezoelectric ceramic phase (as PZT) and high molecular polymer (as PVDF).Piezoceramic material has that piezoelectric property is excellent, dielectric loss is low and the advantage such as electromechanical coupling factor is large, but its one-tenth is hard and crisp, not easily processing and forming, and impact resistance is poor.And although piezopolymer has that density is low, pliability good, can be prepared into large and uniform film, but its piezoelectric property is poor.
In current piezo-electricity composite material system, be full of mutually by organic polymer between piezoelectricity particle in 0-3 type piezo-electricity composite material, ceramic particle connectedness is poor, and dielectric constants is comparatively large, causes its ceramic phase to polarize difficult; The difference of two alternate mechanical properties causes the conduction of its two alternate power comparatively difficult simultaneously; Finally cause composite material piezoelectric property poor.
The mode of the raising composite material piezoelectric property reported in current document mainly two kinds (1) improves the volume fraction of ceramic phase, when ceramic phase volume mark is more than 80%, piezoelectric property has and significantly improves, piezoelectric constantd33 can more than 90pC/N, but the too high meeting of ceramic phase volume mark causes composite material toughness poor.(2) add third phase conduction/semiconducting material, object improves the polarization performance of ceramic phase, but often improve limited, and third phase electric conducting material adds and too much can cause some other negative effect, as loss is excessive simultaneously.
Summary of the invention
The purpose of this utility model is the problem in order to solve ceramic phase height volume fraction lower piezoelectric ceramics polymer composite piezoelectric material poor toughness.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of piezoceramic-polymer composite structure, comprise piezoceramic material layer and be arranged on the polymer filament nethike embrane on piezoceramic material layer, described polymer filament nethike embrane is network, piezoceramic material layer is separated into one-dimensional array structure by polymer filament nethike embrane, and the piezoceramic material of described piezoceramic material layer is 0-3 type piezo-electricity composite material.
