The present invention discloses a preparation method for a fluorinated POSS/polysiloxane hybrid coating and the anti-icing application thereof The coating is prepared by mixing fluorinatedpolyhedral oligomericsilsesquioxanes (fluorinated POSS) comprising Si-H bonds and fluoro alkyl chains in the eight vertices with polysiloxane, and subsequently curing via hydrosilylation. Fluorinated POSS aggregates on the surface of the polysiloxane hybrid coating due to the low surface energy fluorinated chains, leading to the generation of micro/nano-sized wrinkles. The wrinkles, together with lubricant, contribute to the low water contact angle hysteresis (as low as 2°) and ice shear strength (as low as 20 kPa). The required materials are easy to obtain, and the preparation is simple and controllable. All the above make it promising as anti-icing coatings.

A curable composition includes a functionalized fluoropolyether comprising at least one first free-radically reactive functional group, a functionalized polysiloxane comprising at least one second free-radically reactive functional group, and an effective amount of a free-radical curing system. The curable composition can be cured to making a fluoropolyether-polysiloxane elastomer. Compositions and shaped articles including the fluoropolyether-polysiloxane elastomer are also disclosed.

Fired clay moldings are hydrophobicized by applying a long chain alkyl-substituted alkoxysilane or hydrolysate thereof having up to 5 silicon atoms, and an alkoxy-functional silicone resin. The moldings, which may be roof tiles, are hydrophobicized to a significant depth, without discoloration.

A siloxane polymer contains a silsesquioxane unit and a linear siloxane unit in its main chain and has a cage-type silsesquioxane structure in its side chain. A highly transparent and flexible film having a small linear thermal expansion coefficient is produced by utilizing the cohesion force (physical crosslinking) of the cage-type silsesquioxane in the side chain. The siloxane polymer has repeating units respectively represented by formulae (1) and (4), and has terminal groups respectively represented by formulae (5L) and (5R) at its right and left terminals, wherein A represents a structure shown below.
