Resin sheet production method
A resin sheet production method includes a preparation step of preparing a resin molding sheet including a base and a thermally expansive layer that is formed on one main surface of the base, the thermally expansive layer including a thermally expandable material; a heat conversion layer forming step of forming a heat conversion layer that converts electromagnetic waves to heat on at least one of the first main surface of the resin molding sheet or a second main surface on a side opposite to the first main surface; a pre-heating step of heating the resin molding sheet on which the heat conversion layer is formed to a temperature that is lower than an expansion starting temperature at which the thermally expandable material starts to expand; and a main heating step of irradiating the heat conversion layer of the resin molding sheet that is heated in the pre-heating step with the electromagnetic waves to cause the heat conversion layer to distend, thereby causing the base to deform and forming a shaped object on the resin molding sheet.

SYSTEM AND METHOD FOR USING A VOC FREE LOW RADIANT FLUX LED UV CURABLE COMPOSITION
The present invention generally relates to a system and method for using a volatile organic compound (VOC) free low radiant flux LED UV curable composition, and more particularly to unique and novel uses of the composition such as one or two or more of a fire retardant, clear coat, composite material, resin, top coat, improved holdout coating, a sealant coat, and combinations of the same.
Systems and methods for modifying mesa sidewalls
An apparatus, method, or platter for modifying mesa sidewalls of a template by cleaning or coating the mesa sidewalls. In which the template has a pattern area on a first surface of a mesa. Mesa sidewalls surround the first surface of the mesa. The mesa sidewalls are exposed to a gas. The gas modifies the mesa sidewalls. Resistance to the flow of gas towards the pattern area is provided.
POLYORGANOSILOXANE-BASED COMPOSITION INTENDED FOR TYRE MOULDING/STRIPPING
The present invention relates to compositions in the form of silicone oil emulsions intended to be applied to curing bladders as a mould-release agent during tyre production.
Reducing adhesive failure during nanoimprint lithography demolding
Embodiments relate to a method of fabricating a nano-sized structure in a resin element by nanoimprint lithography (NIL). The method reduces adhesive failure during NIL demolding by inhibiting polymerization at the interface between the resin element and the template. The template includes a polymerization inhibiting compound. The method includes pressing the template onto the resin element (or the resin element onto the template) to form the nano-sized structure in the resin element. The method also including diffusing the polymerization inhibiting compound from the template to the resin element, e.g., by holding them together for a period of time. A layer of the polymerization inhibiting compound is therefore formed at an interface of the template and resin element. The polymerization inhibiting compound inhibits polymerization at the interface. After the diffusion, the resin element is cured. Then the template is removed from the resin element.
Process for producing tack-free hotmelt material and device for producing the same
The present invention relates to a process for producing a hot melt adhesive (HMA) material, preferably hot melt pressure sensitive adhesive (HMPSA) material, having a substantially tack-free coating comprising a novel moulding and spraying step, wherein said HMA material, preferably HMPSA material, can be easily handled, packed and transported for further use. In addition, the present invention relates to a corresponding device for producing a hot melt adhesive (HMA) material, preferably hot melt pressure sensitive adhesive (HMPSA) material, having a substantially tack-free coating.
Method for forming pattern
A pattern forming method includes: preparing a pattern paper comprising a fiber where a pattern to be formed is formed; impregnating the pattern paper with a releasing agent; and forming the pattern on a pattern forming target by arranging the pattern paper on a mold comprising an upper mold and a lower mold, and adhering the pattern paper to the pattern forming target by using the mold.
SEMIPERMEABLE ULTRATHIN POLYMER MEMBRANES
A semipermeable ultrathin polymer membrane comprises a substantially optically transparent polymer film having a surface area to thickness ratio of at least 1,000,000:1, and an array of precisely spatially ordered pores of a user-selected diameter defined therethrough. Such membranes can be fabricated by providing a mold having a patterned array of nanoholes femtosecond laser ablated in a surface thereof; applying a first polymer solution onto the mold surface so that the first polymer solution infiltrates the nanoholes; allowing the first polymer solution to dry and form a replica of the mold having a plurality of freestanding nanoneedles extending from a surface of the replica; removing the replica from the mold; coating the replica surface with a second polymer solution; drying the second polymer solution to form a porous polymer film; and dissolving the replica in a solvent to release the film from the replica as a semipermeable ultrathin polymer membrane.
