Name ：Sheet-like nanodiamond（~70nmï¼?/span>
Product Overview
Diamond has extremely high chemical stability and almost does not react with most chemical substances at normal temperature and pressure. Diamond nanosheets also have good chemical stability, mainly due to the strong covalent bonds between carbon atoms in their crystal structure. This chemical stability enables diamond nanosheets to maintain the stability of their structure and properties in a variety of harsh chemical environments. For example, in corrosive media such as strong acids, strong alkalis or strong oxidants, diamond nanosheets are usually not easily corroded or decomposed. CVD is a common method for preparing diamond. In the CVD process, carbon-containing gases (such as methane, acetylene, etc.) are usually used as carbon sources, and under certain temperature, pressure and atmosphere conditions, diamond nanosheets are deposited on the substrate through chemical reactions. For example, in the hot wire CVD method, by heating a metal wire such as tungsten or tantalum wire to a high temperature (about 2000-2500 ° C), the carbon source gas is decomposed and diamond is deposited on the substrate.
By adjusting the parameters in the CVD process, such as the type and flow of carbon source gas, deposition temperature, pressure, substrate material, etc., the size, shape and quality of diamond nanosheets can be controlled. The liquid phase ultrasonic stripping method is a common method to prepare diamond nanosheets. The bulk diamond is dispersed in a suitable solvent, and then the diamond crystal is stripped in the solvent by ultrasonic treatment to form diamond nanosheets. Common solvents are surfactant aqueous solution, organic solvent and so on. In the ultrasonic process, the ultrasonic energy will produce a cavitation effect in the solvent, and the local high pressure and high temperature generated by this cavitation effect can destroy the interlayer force of the diamond crystal and promote the formation of nanosheets.
