Embodiment 1
[0024] The fluorocarbon film rubber stopper in this embodiment includes a rubber stopper body, the surface of the rubber stopper body is entirely covered with a fluorocarbon polymer film, and the rubber stopper body and the fluorocarbon polymer film are integrated by physical and / or chemical bonding In one piece, there is no adhesive in between.
[0025] The content of carbon atoms in the fluorocarbon polymer film is 30-50%, and the content of fluorine atoms is 50-70%.
[0026] The thickness of the fluorocarbon polymer film is about 1 μm.
[0027] Manufacturing method of fluorocarbon membrane rubber stopper:
[0028] The surface of the common rubber stopper is cleaned and dried, then placed in the deposition chamber of the plasma enhanced chemical vapor deposition (PECVD) equipment and evacuated to 1??10 -1 Pa or less. When the deposition chamber temperature rises rapidly to 100 o After C, enter C with a flow rate of 50~100sccm 4 F 8 gas; adjust the air pressure of the ...
