Problems solved by technology

[0005] However, antifouling coatings formed by hitherto known methods have insufficient antifouling properties, and in particular, it is difficult to remove dirt such as fingerprints, skin oil, sweat, and makeup therefrom
In addition, when used for a long time, its antifouling property is greatly reduced

Embodiment

[0088] The following examples are used to describe the present invention in detail, but not to limit the scope of the present invention.

Synthetic example 1

[0090] Add 411.2 g (F 3 CCF 2 CF 2 (OCF 2 CF 2 CF 2 ) 11 OCF 2 CF 2 CH 2 OCH 2 CH=CH 2 ), 286.13 g of 1,3-bis(trifluoromethyl)benzene and 110.47 g of trichlorosilane. The contents were heated to 60° C. before adding 0.045 g of Pt metal complexed with 1,3-divinyl-1,1,3,3-tetramethyldisiloxane over 3.7 hours. Keep the contents at 60 °C for an additional 30 min to make F 3 CCF 2 CF 2 (OCF 2 CF 2 CF 2 ) 11 OCF 2 CF 2 CH 2 OCH 2 CH 2 CH 2 SiCl 3 . Residual trichlorosilane and solvent were removed from the reaction mixture in vacuo before adding 156.5 g trimethyl orthoformate and 1.8 g methanol. The contents of the flask were kept at 60°C overnight to promote methoxylation of the chlorosilanes. After 14 hours an additional 5.2 g of methanol was added and the temperature was maintained for 3 hours. Add 2.5 g of activated carbon. Excess reagents were removed under vacuum. The product was filtered through a bed of diatomaceous earth (Celite) filter aid on ...

Synthetic example 2

[0092] To a 25 mL two-necked flask equipped with a magnetic stir bar, reflux condenser, temperature control and headspace purged with dry nitrogen was added 7.52 g (F 3 CCF 2 CF 2 (OCF 2 CF 2 CF 2 ) 11 OCF 2 CF 2 CH 2 OCH 2 CH=CH 2 ), 12.02 g of 1,3-bis(trifluoromethyl)benzene and 3.91 g of trimethoxysilane. Slowly add 1.4×10 over 16 hours -3 Before g Pt metal complexed with 1,3-divinyl-1,1,3,3-tetramethyldisiloxane, the contents were heated to 100 °C. After two more hours, excess reagent was removed under vacuum. Product F 3 CCF 2 CF 2 (OCF 2 CF 2 CF 2 ) 11 OCF 2 CF 2 CH 2 OCH 2 CH 2 CH 2 Si(OMe) 3 Separated as flask residue, mixed with charcoal and filtered. IR and NMR spectroscopic analysis revealed no starting CH 2 =CHCH 2 The O functional group remains.
