Abstract

The invention discloses a microdroplet spray device, and a method for preparing a CNTs film by deposition through the microdroplet spray device, and aims to solve the technical problem that the CNTs film prepared by a current microdroplet spray device is poor in quality. According to the technical scheme adopted by the invention, the microdroplet spray device comprises a pressure controller, a vibration driver, a three-dimensional motion base plate, a spray nozzle, a resonant glass tube, a piezoelectric ceramic tube, a computer, and a three-dimensional motion base plate controller. The method for preparing the CNTs film by deposition through the microdroplet spray device comprises: regulating the pressure controller, so that a CNTs suspension liquid at the spray nozzle has back pressure; then, driving the piezoelectric ceramic tube to generate quick vibration by virtue of the vibration driver, transmitting the vibration to the CNTs suspension liquid in a micro-channel resonant cavity through the resonant glass tube, thereby realizing spraying of tiny microdroplets of the CNTs suspend liquid; and controlling the three-dimensional motion base plate to carry out three-dimensional motion by virtue of the computer, thereby completing preparation of the CNTs film. The preparation of the CTNs film with a controllable dimension is carried out, according to a designation part, in an open environment, so that quality of the CNTs film is improved.

Description

Technical field [0001] The invention relates to a droplet jetting device, and also relates to a method for preparing carbon nanotubes (hereinafter referred to as CNTs) films by using the droplet jetting device to deposit. Background technique [0002] The trend of modern electronics industry towards high performance, miniaturization and integration has put forward higher requirements on the structure and performance of basic electronic devices. Existing electronic devices are difficult to meet the market's pursuit of high-performance electronic devices due to the limitations of the nature of the materials. CNTs due to their excellent electrical, chemical and mechanical properties, such as excellent thermal conductivity, good mechanical strength, pure semiconducting CNTs, compared with the existing semiconductor materials, can carry larger current and have higher The switching frequency is even hopeful to exceed the limit of the semiconductor industry at this stage and become the...
