Roll-to-roll fabrication of large-scale polyorgansiloxane thin film with high flexibility and ultra-efficient atomic oxygen resistance
文献摘要：
One of the most widely used and well-established atomic oxygen(AO)protection solutions for low Earth orbit(LEO)satellites is the deposition of protective coatings on polymeric materials.However,manufacturing extensive expanses of these coating materials with good transparency,flexibility,smoothness,ultra-thinness,and exceptional AO resistance remains a critical issue.Herein,we successfully deposited a 400 nm thick polyorgansiloxane(SiOxCyHz)coating with high optical transparency and uniform good adherence on to a 1.2 m wide polyimide surface,by optimizing the distribution of hexamethyldisiloxane and oxygen as precursors in the roll-to-roll compatible plasma-enhanced chemical vapor deposition process.After AO irradiation with the fluence of 7.9 x 1020 atoms·cm-2,the erosion yield of the SiOxCyHz-coated Kapton was less than 2.30×10-26 cm3.atom-1,which was less than 0.77％of that of the Kapton.It indicates that the SiOxCyHz coating can well prevent the erosion of Kapton by AO.In addition,it was also clarified that a SiO2 passivation layer was formed on the surface of the SiOxCyHz coating during AO irradiation,which exhibited a'self-reinforcing'defense mechanism.The entire preparation process of the SiOxCyHz coating was highly efficient and low-cost,and it has shown great potential for applications in LEO.
