The curing bladder for a tire has a shape of revolution around a central axis and comprises a flexible wall made of crosslinked rubber. The surface of the wall is covered with a coating film made of a non-stick composition. When the bladder is non-inflated, the coating film has a variable thickness over the surface.

A pattern imprint template incudes a patterned recesses and a layer formed over the patterned recesses. The pattern recesses form a pattern in a resist when brought in contact with a substrate with a resist thereon. The layer formed over the patterned recesses has a first surface energy. The first surface energy is lower in comparison to a second surface energy of the substrate with the resist thereon. The lower first surface energy in comparison to the second surface energy of the substrate avoids trapping gas in the resist by pushing gas toward the imprint template for venting through the patterned recesses.

Fabricating a high refractive index photonic device includes disposing a polymerizable composition on a first surface of a first substrate and contacting the polymerizable composition with a first surface of a second substrate, thereby spreading the polymerizable composition on the first surface of the first substrate. The polymerizable composition is cured to yield a polymeric structure having a first surface in contact with the first surface of the first substrate, a second surface opposite the first surface of the polymeric structure and in contact with the first surface of the second substrate, and a selected residual layer thickness between the first surface of the polymeric structure and the second surface of the polymeric structure in the range of 10 m to 1 cm. The polymeric structure is separated from the first substrate and the second substrate to yield a monolithic photonic device having a refractive index of at least 1.6.

The present invention relates to the technical field of flexible drag reduction coatings, and in particular to a method for preparing a flexible and elastic drag reduction film. The flexible and elastic drag reduction film prepared by the present invention has excellent flexibility and elasticity. The film has a groove structure on a surface, and is suitable for curved surfaces and pipe surfaces of different diameters. The film is directly used without the need for an adhesive. It is sheathed on curved structures or devices of different diameters and curvatures by virtue of its own flexibility and elasticity, reducing an error due to the film adhesion.
