Lab heat flash film forming machine

The CY-H-FV-200 heating flash evaporation film-forming instrument is an auxiliary film-forming and crystallization equipment. This equipment is mainly designed for the process of preparing perovskite thin films by the solution method. The equipment can create vacuum conditions. Under vacuum conditions, the boiling point of the liquid is reduced, which accelerates the evaporation of the solvent and is beneficial to the formation of perovskite thin films. The film placement surface inside the equipment is a heating platform, which can heat the film (and an infrared baking device can be optionally added on the top at the same time). The film crystals after flash evaporation treatment are dense and uniform. This equipment is suitable for laboratories and scientific research institutions to develop perovskite thin films.

Product Overview:

The main working principle of the heating flash evaporation film-forming instrument is to utilize the difference in saturated vapor pressure of substances at different temperatures. By reducing the pressure, the liquid substance evaporates rapidly, realizing the transformation from liquid to gaseous state. This kind of equipment is usually composed of a tank, a feed pipe, a discharge pipe, a steam pipe, an exhaust pipe, etc. The interior is made of stainless steel material, which has good corrosion resistance, high temperature resistance and pressure resistance.

Application Case: Lab heat flash film forming machine

The process of synthesizing graphene materials using a heated flash evaporation film apparatus is as follows:

Initial State: Graphite powder starts in a solid state, with carbon atoms arranged in a layered structure and held together by van der Waals forces between adjacent layers.

Instantaneous Heating: In the flash Joule heating method, graphite powder is subjected to instantaneous high-energy electrical current or laser heating, causing its temperature to rise rapidly. During this process, the internal energy of the graphite powder increases, weakening the van der Waals forces between the carbon atoms.

High-Temperature State: When the graphite powder reaches a sufficiently high temperature, the carbon atoms begin to vibrate thermally, causing the layered structure to gradually separate. Bonds between carbon atoms break, forming free carbon atoms.

Rapid Cooling: At the high-temperature state, rapid cooling is used to quickly solidify the carbon atoms in a new structure, resulting in the formation of graphene.

Extraction and Dispersion of Graphene: Graphene synthesized is effectively dispersed in water or other solvents through centrifugation and ultrasonication, forming a stable graphene dispersion.

Characterization and Analysis of Graphene: Techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy are used to characterize and analyze the synthesized graphene in detail.

These steps outline the basic process of synthesizing graphene using a heated flash evaporation film apparatus, from the initial graphite powder to the final graphene product, with each step being crucial for achieving high-quality graphene synthesis.
