Composite soft form board liquid material plasma spray method for preparing gas-sensitive coating of hollow micro-nano structure

The invention discloses a composite soft form board liquid material plasma spray method for preparing a gas-sensitive coating of a hollow micro-nano structure and belongs to the technical fields of engineering and material science. The spray method comprises the specific steps that suspension liquid of a hollow spherical shell structure serves as a liquid material, wherein the suspension liquid issynthesized through a composite soft form board method; the gas-sensitive coating of the hollow micro-nano structure is prepared in a manner of liquid material plasma spray; and high response is madeto specific gas under the conditions of the low temperature even the room temperature, and the response/recovery time of the gas-sensitive coating is shorted, and long-time stability of the gas-sensitive coating is good. The gas-sensitive coating prepared through the method is controllable in structural appearance, high in specific surface area, good in gas-sensitive performance and low in cost. 本发明公开了种制备中空微纳结构气敏涂层的复合软模板液
