A method of assembling an adjustable fluid-filled lens assembly comprising biaxially tensioning an elastomeric membrane to a surface tension of greater than 180 N/m, typically greater than 1000 N/m; thermally conditioning the tensioned membrane, e.g., for one hour at a temperature of about 80 C., to accelerate relaxation of the membrane; mounting the membrane to a peripheral support structure whilst maintaining the tension in the membrane; assembling the mounted membrane with one or more other components to form an enclosure with the membrane forming one wall of the enclosure; and thereafter filling the enclosure with a fluid. The membrane may be formed from an aromatic polyurethane, and the fluid may be a phenylated siloxane. In some embodiments, the membrane is able to hold a substantially constant surface tension of at least 180 N/m for a period of at least 12 months.

[Problem] It is intended to provide a formed article for food which has excellent antistatic properties and water repellency without impairing its original external appearance and mechanical properties thereof even in a deep-drawn part having a high drawing ratio at forming or even through high temperature forming. [Solution] A multi-layer sheet is prepared having a multi-layer configuration with two or more types of two or more layers, including a main layer which contains a thermoplastic resin, talc and white pigment, and a skin layer of an antistatic resin composition which contains at least one type of thermoplastic resin and an antistatic agent on an opposite side. By thermoforming the sheet including the resin composition, a formed article which has excellent antistatic properties and water repellency effective for preventing contamination and adhesion of soup powder can be obtained. The polymer antistatic agent desirably contains a fatty acid ester sulfonate salt as a main component, has a surface resistivity of 10.sup.13/ or less, and has a water droplet contact angle of 90 or more. The multi-layer sheet is desirably prepared by co-extrusion.

Techniques for overmolding a composition onto a substrate are disclosed. More particularly but not exclusively, techniques for overmolding a therapeutic composition onto a substrate configured for delivery of the composition to teeth and/or oral tissue are disclosed. The overmolding techniques may include injection molding the therapeutic composition onto the substrate, and the therapeutic composition may include one or more therapeutic agents effective for treating one or more oral conditions.

A method of forming a liquid lens, comprising the steps of: positioning a first substrate defining a hole over a second substrate, wherein a cavity is defined within the second substrate and aligned with the hole; dispensing a second liquid into the cavity defined within the second substrate; capping the second liquid with a first liquid dispensed through the hole, wherein the first liquid and the second liquid have different refractive indices than each other; and translating at least one of the first substrate and the second substrate such that the hole is not aligned with the cavity.

A sold nano- or micro-structured thermoplastic foil including a nano- or micro-structured surface area is produced by providing an extrusion casting roller for an industrial polymer extrusion casting process using a thermoplastic material, applying a nano- or micro-structured surface on the extrusion casting roller, maintaining a temperature of the casting roller below a solidification temperature of the thermoplastic material while the casting roller and the counter roller are rotating, and continuously applying a melt of the thermoplastic material between a counter roller and the casting roller while the casting roller and the counter roller are rotating. A rotational velocity of the casting roller may be 10 meters/minute. The melt of the thermoplastic material is moved between the casting roller and the counter roller while the rollers are rolling, and the melt of the thermoplastic material is solidified upon contact with the casting roller to form the thermoplastic foil.

A method of creating a hydrophobic polymer membrane surface includes depositing a polymer material onto a heated carrier, using the heated carrier, transporting the polymer material past an electrode field generator, generating an electric field adjacent the carrier, using the electric field to form a pattern in the polymer material to form a patterned polymer membrane, rinsing the patterned polymer membrane in a first bath, and setting the pattern into the patterned polymer membrane in a second bath.

A three-dimensional shaped article has a sea-island structure including a cured object of a first shaping ink, which contains a hydrophobic resin, and a cured object of a second shaping ink, which contains a hydrophilic resin.

Modeling material formulation systems usable in additive manufacturing, 3D inkjet printing in particular, of three-dimensional objects, are provided. The formulations comprise two or more curable materials, such that an average molecular weight of the curable materials in each formulation is no more than 500 grams/mol, such that each formulation features a viscosity of no more than 50 centipoises at a temperature of 35 C. Kits comprising the formulations or formulation systems and additive manufacturing processes utilizing same are also provided.
