Problems solved by technology

Although this flow can ensure the best aerodynamic environment for film growth, it is difficult to achieve the gas flow required for the rapid discharge of reaction by-products
The traditional PET flexible functional film coating system only sets a unified gas flow rate, and cannot implement separate flow control for the surface deposition process and the emptying process of reaction by-products

Embodiment 1

[0041] To plate barrier Al on the surface of PET flexible base film 2 o 3 Taking the functional membrane as an example, the precursor fluid response sources are TMA and H 2 O. TMA and H 2 The O sources are installed in two different reaction source arrays (see figure 1 Two different reactive source arrays in 41) to avoid their possible in-line mixing. The average temperature in the reaction chamber is 150°C, the sample heating temperature is 250°C, and the gas pipeline temperature is 50°C. The time sequence of reactant injection and by-product evacuation for single-layer coating is: 100 milliseconds H 2 O molecule injection + 500 millisecond reaction by-product discharge + 100 millisecond TMA molecule injection + 300 millisecond reaction by-product discharge. The system uses BOCEdwards mechanical vacuum pumps to establish a vacuum environment in the reaction chamber. Flow control adopts MKS company IP66 series mass flow controller (MFC). The air valve adopts the DL ser...

Description

technical field [0001] The invention belongs to the technical field of coating, in particular to a PET flexible functional film coating system. Background technique [0002] In the development of modern science and technology, especially in the development of nanoscience and technology, almost all related applications involve nano-coating technology for the purpose of realizing various surface functions, especially nano-coating technology that can control the thickness at the atomic scale . In the selection of coating methods, although the wet chemical method under liquid phase conditions is low in cost, it is difficult to form a uniform and dense high-quality nano-coating layer of equal thickness. The currently widely used nano-coating technologies are based on nano-coating technologies under gas phase conditions, such as physical vapor deposition, chemical vapor deposition, and atomic layer deposition. Among them, the atomic layer deposition technology has a unique surfa...
