Abstract

The invention discloses the application of a black phosphorus carbon nanotube composite material as an electrostatic response driver, and relates to the technical field of flexible intelligent film drivers. The driver includes a black phosphorus layer and carbon nanotubes. Between adjacent black phosphorus layers, carbon nanotubes and black phosphorus layers are bonded by covalent bonds, and the thickness of the driver is 20-30 μm. The beneficial effects of the present invention are: the electrostatic driving operation is simple, the controllability is strong, the driving source is easy to obtain, and it can avoid the self-decomposition of the material directly contacting the strong stimulus source, which improves the cycle stability of the driver. By using this stimulus source The characteristics can effectively improve the performance and application range of the driver.

Description

technical field [0001] The invention relates to the technical field of flexible intelligent thin film drivers, in particular to the application of a black phosphorus carbon nanotube composite material as a non-contact electrostatic response driver. Background technique [0002] The driving device composed of flexible smart materials can respond specifically to external stimuli such as electricity, magnetism, heat, humidity, etc., and change its shape and size within a certain range. With many advantages such as good adaptability, it is widely used in the fields of micro-bionic robots, artificial muscles, and intelligent drives. [0003] Most of the drivers currently researched need to be driven by strong external stimuli (such as strong light, strong magnetic field, high voltage, etc.), which may lead to oxidation or decomposition of the material surface, thereby affecting the service life of the device. The patent with the publication number CN107029565A discloses a graphe...
