An improved liner for a container in which gases, liquids, or powders are stored. The liner is a multi-layer structure made in a roto molding machine. The liner includes a first outer layer made of metallocene polyethylene, an intermediate gas and liquid impermeable layer, and one or more inner layers made of thermoplastic material compatible with the material stored inside the container. During the molding process, the three layers are made sequentially with the second and third layers being bonded and fused to the adjacent layer to form a uniform composite layer. The outer layer is made of metallocene polyethylene with superior rigidity and relatively low coefficient of thermal expansion making the liner less susceptible to cracking and useful as a layup structure for molding a structure around it. The liner is then used as a layup structure for outer fibers and infused resin.

Provided is a rotating assembly. The rotating assembly is for forming a microstructure, and comprises: a rotating body rotatable about a rotary shaft; a first support member installed on the rotating body so as to be spaced apart from the rotational shaft and having a predetermined viscous composition disposed on an outer surface thereof; and a fluid communicating portion for communicating the inside and the outside of the rotating body, wherein when the rotating body rotates, the viscous composition is pulled in a radially outward direction of the rotary shaft, and the pulled viscous composition is cured through the fluid communicating portion, thereby forming a microstructure.

The present invention relates to an ultrahigh sensitive pressure-sensing film based on spiky hollow carbon spheres and the fabrication method thereof. The fabricated spiky hollow carbon spheres composed polydimethylsiloxane sensing film whose spheres were well dispersed in the matrix. The spiky structure is useful for the spheres to trigger Fowler-Nordheim (F-N) tunneling effect and thus enhancing the sensitivity of the material. The carbon material fabricated by the precursor transformation method contains a proper Nitrogen doping, which has efficiently increased the carrier migration ability. The hollow structure can both regulate the density of fillers and help to improve its temperature independence. Calcine the spheres under an inert atmosphere to transform the spiky hollow organic spheres into a carbon one, in this process the Nitrogen fraction and graphitization can be adjusted. The above carbon spheres then can be assembled with polydimethylsiloxane to achieve the composite film. The material of the present invention exhibits ultrahigh sensitivity, high sensing density, transparent, low hysteresis, temperature noninterference, and its processing method is simple, maturity and environment friendly.

One embodiment of a contact lens includes a lens body configured to fit directly on the surface of the eye and legible characters positioned on the lens body. Another embodiment of a contact lens comprises a lens body including polymeric material and a lens enhancing material (e.g., ink, silicone material, medicament material, and the like) encapsulated in the polymeric material. The lens enhancing material can be in the form of isolated sections distributed in the surrounding polymeric material. Methods of making contact lenses include forming a first lens layer including a first surface, forming a pattern on the first surface, and forming a second lens layer over the pattern.

Discloses is a method of manufacturing a micro-needle. The method includes a step of preparing a medicinal solution, a step of forming a plurality of tips with the medicinal solution, and a step of forming a cavity in each of the tips. In accordance with such a configuration, a micro-needle in which cavities are formed is provided, whereby it is possible to administer a fixed amount of medicine in a short time.

Processes for fabricating structured, relatively large area, ultra-thin polymer films are disclosed. For instance, such a process may include spinning a thermoplastic polymer film onto an etched wafer that serves as a mold for the thermoplastic polymer film, baking the thermoplastic polymer film on a hotplate at a curing temperature, delaminating the thermoplastic polymer film in water, and peeling the thermoplastic polymer film from the etched wafer, producing a structured thermoplastic polymer film that has structures corresponding to areas where the wafer has been etched.

A polarizing film having a molded shape, in which a difference in average transmittance of the polarizing film at a wavelength of 400 to 700 nm is 5% or less before and after molding the shape of the polarizing film. In addition, when molding the polarizing film into a shape such as a curved surface, the polarizing film is heat-treated in a temperature range of Tg20 C. or higher and Tg+10 C. or lower, where Tg is a glass transition point of a resin constituting the polarizing film. Further, one chamber is divided into a first space and a second space by the polarizing film disposed in the chamber, and the polarizing film is transfer-molded along a molding surface by a differential pressure generated by making a pressure in the first space and a pressure in the second space different from each other.
