Embodiment 1
[0217] Embodiment 1 [Rf (C6) methacrylate / microparticle] the making of copolymer / TAHFNHA=60 / 40 (w / w) film
[0218] [Preparation of [[Rf(C6)methacrylate / microparticle] copolymer solution]
[0219] Fill C in the test tube with branch 6 f 13 CH 2 CH 2 OCOC (CH 3 )=CH 2 [Hereinafter, it may be abbreviated as Rf (C6) methacrylate] 25.46 g, 12.70 g of silica microparticles having a radical reactive group on the surface and an average primary particle diameter of 12 nm, and 663.49 g of perfluorobutyl ether , purged with nitrogen, and heated to 70°C. 1.26516 g of AIBN was put into it, and it was reacted for 6 hours. After polymerization, the solid content concentration was calculated.
[0220] (Preparation of photosensitive solution)
[0221] 0.3256 g of triacryloylheptadecafluorononenyl pentaerythritol (hereinafter, sometimes abbreviated as TAHFNHA), 0.0413 g of alkylphenone-based photopolymerization initiator, 1.0949 g of IPA, and 7.4783 g of perfluorobutyl ethyl ether we...
Embodiment 2
[0224] Embodiment 2 [Rf (C6) methacrylate / microparticle] the making of copolymer / TAHFNHA=50 / 50 (w / w) film
[0225] Except that 0.4157g of TAHFNHA, 0.0404g of alkylphenone-based photopolymerization initiator, 1.0675g of IPA, 9.5001g of perfluorobutyl ether, and 9.6917g of copolymer solution in the item (preparation of photosensitive solution) , Prepared by the same method as in Example 1. The fluorine atom content of the produced film was 42.3 wt % with respect to the constituent components of the entire film.
Embodiment 3
[0226] Embodiment 3 [Rf (C6) methacrylate / microparticle] the making of copolymer / TAHFNHA=40 / 60 (w / w) film
[0227] Except that 0.4817g of TAHFNHA, 0.0402g of alkyl phenone-based photopolymerization initiator, 1.1468g of IPA, 11.5713g of perfluorobutyl ether, and 8.0478g of copolymer solution in the item (preparation of photosensitive solution) , Prepared by the same method as in Example 1. The fluorine atom content of the produced film was 43.3 wt % with respect to the constituent components of the entire film.
