Abstract

The electrostatic spinning process for preparing low density porous nanometer SnO2 fiber as laser target material is fast, efficient and simple. The electrostatic spinning process includes compound spinning solution with polyvinyl pyrrolidone, absolute ethyl alcohol, tin tetrachloride in certain weight proportion through mixing at room temperature; electrostatic spinning through spraying the spinning solution with spinning jet to an accepting screen 5-30 cm apart from the jet while applying electric field of 0.1-1 kv / cm, controlling the spraying time and the motion of the accepting screen to obtain fiber of different density and deposited in different areas; and roasting at 450-550 deg.c to obtain the nanometer SnO2 fiber.

Description

technical field

[0001] The invention relates to the raw material formulation of low-density nano material and the preparation of laser target material. The invention belongs to the technical field of tin dioxide nanofiber laser target material preparation. Background technique

[0002] To prepare porous materials with low density and different pore sizes, the conventional preparation methods are as follows: 1. Sol-gel method, the sol is formed into a gel by chemical reaction or physical means, and then the solvent is removed by supercritical extraction or freeze-drying Obtain porous material; 2. High internal phase emulsion method (HIPE), first prepare water-in-oil type high internal phase emulsion by emulsification, then polymerize the oil phase, and finally remove solvent by replacement and drying to obtain porous material; 3. Polymer And the solvothermal-induced phase separation method, firstly use phase separation to prepare polymer gel or crystal, and then remove the s...
