Preparation and post-treatment device of multi-parameter accurate and adjustable multi-system microwave assisted nano-material

Abstract

The invention discloses a preparation and post-treatment device of a multi-parameter accurate and adjustable multi-system microwave assisted nano-material. The preparation and post-treatment device comprises a case body, wherein a metal shielding layer is arranged on the outer layer of the case body; a full-coated wave absorption material is arranged on the inner wall of the case body; an infrared temperature measuring device and a directional microwave beam transmission antenna are arranged on the top of the inner wall of the case body; a workbench is arranged at the bottom of the inner wall of the case body; and a sample inlet and outlet part is reserved on the workbench. The preparation and post-treatment device prepared by a multi-parameter accurate and adjustable multi-system microwave assisted nano-material has a simple structure and smart design, and has the following main advantages compared with the traditional microwave assisted device: a plurality of parameters of a microwave system for nanometer synthesis and assembly are accurate and adjustable; the microwave source and the reacting cavity are of a split design; the microwave beam in the microwave reacting kettle is directional, and the wave absorption material is lined in the wall, so the single component of a microwave field close to a nanometer sample bench is ensured, calculation and simulation can be performed by a one-way radar equation, and support is provided for further developing nano-material microwave controlled synthesis and assembly theoretical analysis after experiments.

Description

Precisely adjustable multi-parameter multi-mode microwave-assisted nanomaterial preparation post-processing device technical field The invention relates to the fields of radio frequency, microwave technology and nanomaterial science, in particular to a multi-parameter, precisely adjustable and multi-standard microwave-assisted nanomaterial preparation post-processing device and a test method thereof. Background technique Nanotechnology was born in response to the rapid development of information technology. Currently in the era of knowledge explosion, the amount of information in human society is increasing geometrically. The traditional micron-level precision can no longer meet the needs of human beings. In 1994, IBM developed a read head with the giant magnetoresistance effect, which increased the recording density of the disk by 17 times, and thus regained its leading position in the competition with the optical disk. The 21st century is the century of nanotechnology....

Problems solved by technology

However, there have been reports at home and abroad that microwave heating is used to synthesize nanomaterials with certain functions. Due to the constraints of equipment, it has brought great difficulties to further explore the microwave-assisted mechanism. There are many problems that need further research, such as : How microwaves change the activation energy of reactions, how microwave power, microwave width, and pulse frequency affect reactions, etc.
