本发明属于功能材料技术领域，涉及一种能够实现机械能和电能相互转换的复合结构机电换能材料的制备方法。The invention belongs to the technical field of functional materials, and relates to a preparation method of a composite structure electromechanical transduction material capable of realizing mutual conversion of mechanical energy and electric energy.
背景技术Background technique
换能器是一种能量转换器件，能够将一种形式的能量转化成另一种形式的能量。这些能量形式包括(但不限于)电能、机械能、电磁能(包含光能)、化学能、声能和热能。而在换能器中，起关键作用的即是换能材料。目前，在环境振动能量采集器和生物动能能量采集器中广泛应用的换能材料是压电材料(包括压电陶瓷和铁电聚合物)。压电材料是一种机电换能材料，能够实现机械能和电能之间的转换。A transducer is an energy conversion device that converts one form of energy into another. These forms of energy include, but are not limited to, electrical energy, mechanical energy, electromagnetic energy (including light energy), chemical energy, sound energy, and thermal energy. In the transducer, the key role is the transducing material. At present, piezoelectric materials (including piezoelectric ceramics and ferroelectric polymers) are widely used as transducing materials in environmental vibration energy harvesters and biokinetic energy harvesters. Piezoelectric material is a kind of electromechanical transduction material, which can realize the conversion between mechanical energy and electrical energy.
压电材料又可以分为无机压电材料、有机压电材料及复合压电材料，其可以实现机械能和电能之间的转换，其工作原理为：如果对压电材料施加压力，它便会产生电位差(称之为正压电效应)，反之施加电压，则产生机械应力(称为逆压电效应)，也就是说压电材料可以因机械变形产生电场，也可以因电场作用产生机械变形，这种固有的机-电耦合效应使得压电材料在工程中得到了广泛的应用，现已广泛地应用于各种声电传感器、力学传感器、振动能量采集等领域。Piezoelectric materials can be divided into inorganic piezoelectric materials, organic piezoelectric materials and composite piezoelectric materials, which can realize the conversion between mechanical energy and electrical energy. Its working principle is: if pressure is applied to piezoelectric materials, it will produce Potential difference (called the positive piezoelectric effect), on the contrary, when a voltage is applied, mechanical stress (called the inverse piezoelectric effect), that is to say, the piezoelectric material can generate an electric field due to mechanical deformation, and can also generate mechanical deformation due to the action of the electric field , this inherent electromechanical coupling effect makes piezoelectric materials widely used in engineering, and has been widely used in various acoustic and electric sensors, mechanical sensors, vibration energy harvesting and other fields.
目前，用于制备机电换能材料的方法有很多，申请号为200810067783.X的中国发明专利公布了一种压电复合材料及其制备方法，该压电复合材料包括填充物和至少两层压电材料，根据各层压电材料的极性，相邻层压电材料反向设置，各层压电材料三维连通设置，所述填充物一维连通装置；在所述压电复合材料的各工作面，分别设置工作面电极，在平行于所述压电复合材料工作面的截面中，所述压电材料以规则条形组合的形式连通设置，所述填充物隔离设置。At present, there are many methods for preparing electromechanical transducing materials. The Chinese invention patent with application number 200810067783.X discloses a piezoelectric composite material and its preparation method. The piezoelectric composite material includes fillers and at least two laminated Electric material, according to the polarity of each layer of piezoelectric material, adjacent layers of piezoelectric material are set in reverse, each layer of piezoelectric material is connected in three dimensions, and the filler is one-dimensional connected device; in each layer of piezoelectric composite material On the working surface, working surface electrodes are arranged respectively, and in a section parallel to the working surface of the piezoelectric composite material, the piezoelectric materials are connected in the form of regular strip-shaped combinations, and the fillers are arranged in isolation.
然而，现有的用于制备换能材料的方法往往步骤较为复杂，工艺条件控制较为繁琐，而且方法局限性较大，不能满足多样化工况需求，这会直接限制换能材料的推广使用。However, the existing methods for preparing transduction materials often have complicated steps, cumbersome control of process conditions, and relatively large method limitations, which cannot meet the needs of diverse working conditions, which will directly limit the popularization and use of transduction materials.
