Transfer films, articles made therewith, and methods of making and using transfer films to form bridged nanostructures are disclosed.

A thermochromic device includes a film and a number of vanadium dioxide nanowires disposed within the film. The film is manufactured by hot extruding a material that includes a polymer and a plurality of vanadium dioxide nanowires on a drum to form a rough film.

A sealed module is provided in the present disclosure. The sealed module includes a first substrate with a lens unit and an adhesive geometry formed around the lens unit, a second substrate stacked onto the first substrate, and a sealing wall for sealing the first substrate with the second substrate to form a closed cavity. The lens unit is located in the closed cavity, and the adhesive geometry serves as an adhesive barrier. The adhesive geometry includes glue guiding features for controlling a track of adhesive glue during a stacking process between the first substrate and the second substrate. The present disclosure further provides a method for making a sealed module.

An article includes a layer including a melt processable fluoropolymer, wherein the fluoropolymer includes a copolymer of a tetrafluoroethylene and a perfluoroether, wherein the article has an ultraviolet transmittance of at least about 50% at a thickness of about 0.040 inches to about 0.062 inches when exposed to ultraviolet radiation of about 200 nm to about 280 nm. Further provided is a method of making the article and an apparatus for purifying water including an article, such as a flexible tube.

A three-dimensional printing apparatus includes a liquid tank. The liquid tank includes a release layer and a plate. The release layer has a workpiece curing area, and the plate supports the release layer and has a first area corresponding to the workpiece curing area and a second area adjacent to the first area; the second area has at least one fluid passage extending from a first surface of the plate contacting the release layer to a second surface of the plate. The embodiments of the present invention facilitate the separation of workpieces from the release layer. Another three-dimensional printing apparatus and a three-dimensional printing method are also provided.

Cables are constructed with embedded discontinuities in the cable jacket that allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of polymer material coextruded in the cable jacket.

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

The present invention provides an interlayer film for a laminated glass capable of providing a laminated glass that reduces the occurrence of optical distortion, a laminated glass including the interlayer film for a laminated glass, and a method for producing the interlayer film for a laminated glass. Provided is an interlayer film for a laminated glass, having a maximum thickness curvature in a width direction of the interlayer film for a laminated glass of 0.010 m.sup.−1 or less.

A manufacturing device for an optical sheet according to the present invention includes a first belt 34 extending on a first heating roll 31 and a first chill roll 32 and a second belt 44 extending on a second heating roll 41 and a second chill roll 42. The first heating roll 31 presses, from the surface of the second belt 44, a second belt non-contact portion PT2 of the second belt 44 facing the first belt 34 where the second heating roll 41 is not in contact with the second chill roll 42. The second chill roll 42 presses, from the surface of the first belt, a first belt non-contact portion PT1 of the first belt 34 facing the second belt 44 where the first heating roll 31 is not in contact with the first chill roll 32.

The present invention provides an optical film containing an additive. The optical film includes a high concentration portion containing the additive, and a low concentration portion containing the additive at a concentration lower than the high concentration portion. The low concentration portion is provided on both sides of the high concentration portion in a thickness direction of the optical film, and the low concentration portion is provided on both sides of the high concentration portion in a width direction of the optical film.
