Abstract

The invention discloses a carbon fiber/zinc oxide-zinc selenide double-shell micro-line nanometer generator nanometer material, a preparation method of the carbon fiber/zinc oxide-zinc selenide double-shell micro-line nanometer generator nanometer material, and application of the carbon fiber/zinc oxide-zinc selenide double-shell micro-line nanometer generator nanometer material, and relates to a piezoelectric material, a preparation method of the piezoelectric material, and application of the piezoelectric material, and therefore the problem that under strain, the output current of an existing zinc oxide composite nanometer material is low is solved. A zinc oxide nanometer line grows in the direction perpendicular to the axis of carbon fiber through the double-shell micro-line nanometer material, and a zinc selenide layer grows on the tip portion of the nanometer line. The preparation method includes the steps of firstly, soaking the carbon fiber in a zinc acetate solution, taking out the carbon fiber, and conducting annealing on the carbon fiber to form carbon fiber with a seed layer; secondly, placing the carbon fiber in an initial solution so that zinc oxide arrays can grow in a hydrothermal mode; thirdly, placing the carbon fiber into reaction liquid so that zinc selenide can grow in a secondary hydrothermal mode, and obtaining a nanometer generator material. According to the carbon fiber/zinc oxide-zinc selenide double-shell micro-line nanometer generator nanometer material, the preparation method and application, controllable growth and stable large-current output of the carbon fiber/zinc oxide-zinc selenide double-shell micro-line nanometer generator nanometer material are achieved, and the double-shell micro-line nanometer generator nanometer material is mainly applied to generator devices.

Description

technical field [0001] The invention relates to a piezoelectric material and its preparation method and application. Background technique [0002] Nanomaterials mainly refer to materials whose spatial dimension is on the order of 1-100nm. Due to their special properties and wide range of uses, they have long been widely concerned by the scientific field and all walks of life. Nanomaterials made of semiconductor materials such as zinc oxide and zinc selenide can exhibit many peculiar and excellent physical properties due to the quantum confinement effect. Compared with ordinary materials, they have stronger mechanical toughness, piezoelectric properties, better thermal conductivity, higher luminous efficiency, wider luminous spectrum, more excellent field emission performance and so on. These excellent characteristics play a pivotal role in the production of large-scale integrated circuit devices, optoelectronic devices, biological and chemical sensor devices, medical and he...
