METHOD FOR MANUFACTURING PDMS DEVICE AND PDMS DEVICE MANUFACTURED THEREBY

A method for manufacturing a PDMS device in accordance with an exemplary embodiment of the present invention surface treats the entire surface of a pattern with a thiol group (—SH), so that a hydrogel may be connected to the surface of the pattern by a covalent bond under ultraviolet rays. Therefore, a PDMS device manufactured by the above method has an advantage in that the shape thereof may be stably maintained without the swelling or desorption of a hydrogel even when an electrolyte is filled in a pattern.

Fluid leak repair
11125376 · 2021-09-21 · ·

Fluid leak repair kits are described comprising a putty, self-amalgamating tape, and a composite material for use in encompassing the self-amalgamating tape. The composite material comprises a flexible sheet or tape and a matrix component for binding the flexible sheet or tape. The matrix component comprises a resin or water-activated matrix component which, when cured, forms an outer shell.

Asymmetric Polytetrafluoroethylene Composite Having A Macro-Textured Surface And Method For Making The Same

Polytetrafluoroethylene (PTFE) composite articles that have a macro textured surface. The composite articles include at least two different PTFE membranes in a layered or stacked configuration. The composite article has a macro textured surface characterized by a plurality of strands raised from the surface of the PTFE membrane. The strands may be formed of either interconnected nodes of PTFE or of at least one nodal mass of PTFE and have a length equal to or greater than about 1.5 mm. The macro textured surface provides a topography to the first PTFE membrane. The composite articles have a bubble point from about 3.0 psi to about 200 psi, a thickness from about 0.01 to about 3.0 mm, and a bulk density from about 0.01 g/cm.sup.3 to about 1.0 g/cm.sup.3.

PRODUCTION METHOD FOR FILM LAMINATE

Provided is a production method for a film laminate by which a tough film can be bonded to a brittle film while the breakage of the brittle film is prevented. The production method for a film laminate of the present invention includes bonding a tough film having an elongated shape to a brittle film having an elongated shape while conveying the brittle film, wherein the method includes bonding the tough film and the brittle film to each other by bringing the tough film close to the brittle film, followed by blowing of a gas from a side of the tough film opposite to the brittle film.
