Embodiment

[0030] First, use a mixed acid solution to remove organic impurities and metal impurities on the surface of the silicon wafer, and then soak the base silicon wafer in acetone, alcohol and ultrapure water for 20 minutes for ultrasonic cleaning. After cleaning, use an ear cleaning ball to blow off the water droplets on the surface of the silicon wafer , dry for later use.

[0031] Paste the cleaned silicon wafer on the circular sample stage with double-sided tape to ensure good adhesion between the silicon wafer and the substrate, then fix the titanium target and aluminum target on the target, and close the vacuum chamber hatch . Turn on the circulating condensate, turn on the main power supply, mechanical pump, side pump valve, compound vacuum gauge, flow meter, radio frequency source power switch, and molecular pump main power supply in sequence. When the reading of the vacuum gauge shows 8Pa, switch the side pumping valve, turn on the molecular pump, and then fully open the ...

Abstract

The invention discloses a nanocomposite energetic film and a preparation method thereof. Porous nano-alumina is used as a supporting material, and carbon nanotubes embedded with azide are arranged in the channels of the supporting material to obtain the energetic film. . In the present invention, azide is embedded in the hollow cavity of aligned carbon nanotubes in alumina channels, forming a new type of nanostructured composite energetic film material, which can not only solve the safety problem of azide use , and to a certain extent, it can improve the explosive performance of azide, and at the same time meet the stability requirements of the engineering application of energetic materials.

Description

technical field [0001] The invention relates to a nanostructure composite energetic film and a preparation method thereof, more specifically a carbon nanotube / alumina composite energetic film embedded with azide and a preparation method thereof. Background technique [0002] With the development of weapon technology, the size, cost and reliability of traditional pyrotechnics have been difficult to meet the demand, and pyrotechnics technology is developing in the direction of miniaturization, intelligence, low cost and high reliability. Among them, Micro-Electro-Mechanical System (MEMS) technology is the main direction of the miniaturization development of pyrotechnics. The emergence of MEMS technology makes it possible for the detonation system to achieve low cost, small size, and high reliability, while leaving more space to accommodate more sensors and main charges, which greatly improves the accuracy and lethality of the ammunition. [0003] So far, the solid energetic m...
