Method and apparatus for preparing silver black nanoparticles through nuclear track porous surface

Abstract

The invention relates to a silver black nanometer material preparation technology, specifically to a method and an apparatus for preparing silver black nanoparticles through a nuclear track porous surface. According to the method, 32S ions are adopted to irradiate a polyester or a CR-39 sample; a NaOH solution etching process is performed to obtain a nuclear track polyester sample or a nuclear track CR-39 sample; the nuclear track polyester sample or the nuclear track CR-39 sample, and a detector sheet are adhered to a sample holder inside a vacuum chamber, and a pressure in the vacuum chamber reaches 3*10<-3>-4*10<-3> Pa; argon is introduced into the vacuum chamber, such that an argon pressure in the vacuum chamber reaches 50-100 Pa; and silver wire in the vacuum chamber is heated so as to melt and evaporate the sliver, and a layer of metal sliver nanoparticles are plated on the surface of the nuclear track polyester sample or the nuclear track CR-39 sample. According to the present invention, a new idea and method is provided for infrared temperature sensitive sensor absorption material silver black preparation, and an enlightenment effect is provided for efficient infrared detector utilization.

Description

technical field [0001] The invention relates to the preparation technology of silver black nano material, in particular to a method and device for preparing silver black nano particles on a nuclear track porous surface. Background technique [0002] Infrared detectors such as thermoelectric infrared detectors, pneumatic infrared detectors, thermistor infrared detectors and infrared thermal cameras have been widely researched and applied in military, national defense and civilian fields, especially in military requirements Driven by the traction and the development of related technologies, the application of infrared detection technology as a high-tech will be more extensive in the future, and its status will be more important. The core component of the infrared detector is the infrared thermal sensor. Only when the thermal sensor transfers the sensed heat effectively and in a timely manner, the infrared detector will respond. Therefore, it is required that the absorbing la...
