[0076] According to an embodiment of the present invention, the overall preparation method of the waterproof nano-membrane may include the following steps:
[0077] 1) Substrate preparation
[0078] Before performing chemical vapor deposition on the substrate, the substrate needs to be cleaned first. Dust, moisture, grease, etc. on the surface of the substrate will adversely affect the deposition effect. Clean the substrate with acetone or isopropanol, and then dry it in a drying oven.
[0079] 2) The substrate is subjected to chemical vapor deposition to prepare a nano-coating.
[0080] (1) Place the substrate with a clean surface in the reaction chamber of the plasma device or equipment, then continuously evacuate the reaction chamber, and evacuate the vacuum degree in the reaction chamber to 1-2000 millitorr;
[0081] (2) Turn on the movement mechanism to make the substrate in a moving state in the cavity; introduce plasma source gas, and use radio frequency discharge or...
Embodiment 1
[0090] Using the PCB board as the base material, the waterproof nano-coating is formed on the surface of the PCB board through the PECVD device, carbon tetrafluoride is used as the plasma source gas, and monomer 1 (1H, 1H, 2H, 2H-perfluorooctyl alcohol acrylate) As the reaction raw material, the specific steps are: (1) The PCB board is placed in a 200L plasma vacuum reaction chamber, and the reaction chamber is continuously evacuated to make the vacuum degree reach 20 millitorr. (2) Feed carbon tetrafluoride with a flow rate of 40 sccm, turn on radio frequency discharge for plasma discharge, and discharge with a discharge power of 100 W for 100 seconds. (3) Vaporize 1H,1H,2H,2H-perfluorooctyl alcohol acrylate (monomer 1) and introduce it into the reaction chamber, and perform chemical vapor deposition on the surface of the substrate to prepare a nano-coating. During the coating preparation process, the monomer vapor flow rate was 120 μL / min, the passage time was 2000 s, and th...
