Embodiment 1

[0019] A molybdenum foil with a thickness of 0.01mm was selected and produced according to the following steps to obtain figure 1 The outer diameter shown is 3mm, the mesh number is 600 mesh, and the mesh is a molybdenum foil mesh with square holes.

[0020] The first step (1) is drawing: first draw manually according to the requirements of the required molybdenum foil mesh, then transfer the manual drawing sketch to the computer for accurate drawing, and then print out the black and white negatives at a ratio of 1:1, forming a pattern on the negatives A picture opposite to the real molybdenum mesh, also called a positive and negative film, as a target for making the real thing.

[0021] Step (2) is molybdenum foil treatment: the surface of the molybdenum foil is cleaned and dried with an ordinary kitchen fume net; the ordinary kitchen fume net is purchased from Beijing Lvsan Chemical Co., Ltd., and its model is Q / HDLSH008.

[0022] The (3) step is glue coating: use conventio...

Abstract

The invention provides a molybdenum foil mesh for a transmission microscope and a scanning microscope. The thickness of the molybdenum foil mesh is from 0.01 mm to 0.05 mm and the number of mesh holes is from 1 mesh to 600 meshes. A production method of the molybdenum foil mesh comprises drawing, molybdenum foil processing, performing photoresist, pre-baking, performing exposure, developing, rinsing, post-baking, etching and removing of photoresist. The production method of the molybdenum foil mesh for the transmission microscope and the scanning microscope has the advantage of enabling obtained mesh holes of electron microscope molybdenum foil meshes to be clear and hole walls of the electron microscope molybdenum foil meshes to be smooth.

Description

technical field [0001] The invention relates to a molybdenum foil net used in a transmission microscope and a scanning microscope and a manufacturing method thereof. Background technique [0002] The copper mesh used in transmission microscopes and scanning microscopes developed before 1975 is far from meeting the needs of more scientific research. On the one hand, in the field of material science research, the temperature is as high as 2000 degrees during the production process of the sample, which requires the surface to be resistant to acid and alkali. However, the traditional copper grid is not resistant to high temperature, the hardness is not enough, and the surface is easily corroded, which makes it impossible to carry out analyze. On the other hand, in the field of scientific research, such as the field of biochemical research, since the field of nanochemistry plays an important role in the research and observation of the structure of nanoparticle carbon nanotubes, ...
