Abstract

The invention relates to a microdomain controllable nanometer functional material synthetic heating device, which solves the problems of enormous volume, dissipation energy, consuming and single synthetic method of the existing nanometer functional material synthetic device. The heating device comprises a rectangle box body and a box cover. Two side walls which are corresponding to the box body are respectively provided with an entering air port connector and an outgoing gas connector. The other two side walls are respectively provided with an electric wire connector. The interior of the box body is sequentially provided with a cooling water pipe, a heat dissipation foundation bed, a workbench, a junction board, a lower panel and an upper panel from bottom to top. The middle of the workbench is provided with a stepped hole which is big at the upper part and small at the lower part. The junction board is provided with a connector lug and a probe. The heating device has small volume; the volume is 240dm3, thereby the heating device is convenient to be moved; the consuming time of vacuumizing is shortened to 5-15 minutes; the heating up and cooling time and the height are controllable; the whole temperature increasing and decreasing course can be finished in 2-10 minutes; the nanometer structure can be prepared on a silicon base with an external circuit; a plurality of nanometer structures can be integrated on the same under layer. The consumption of water, electric and gas reduced to 5-10% of the former.

Description

technical field [0001] The invention relates to a nano functional material synthesis equipment, in particular to a micro-electrode micro-heating device for controlling the local synthesis of nano functional materials. Background technique [0002] Nano-functional materials have very important applications in the new generation of nano-optoelectronics, sensing, storage and other devices. In order to achieve the purpose of device application, it is first necessary to realize the controllable synthesis of nanomaterials, such as controlling the structure, morphology and orientation of nanomaterials according to the requirements of device applications. It must be pointed out that the positioning and directional synthesis of nanomaterials is a difficult technology at present, and it is also a key technology in the synthesis of nanomaterials. At present, there are a variety of synthesis methods for low-dimensional nanomaterials, involving many physical and chemical means, the most...
