Abstract: A water-based hydrogel polymer coating and a method of application to natural rubber or other elastomeric latex products are provided. The water-based hydrogel polymer is mixed with a blend of at least one elastomeric material to provide a hydrogel polymer blend composition. The water-based hydrogel polymer blend composition is applied in a single application to an elastomeric article, such as gloves, without additional solvents in the polymer blend composition and without a separate acid or chemical priming step. The water-based hydrogel coating herein provides increased lubricity to facilitate improved wet and dry donning of the elastomeric article.

Abstract: A method of forming an electrospun prosthetic valve includes utilizing a rotatable and angularly adjustable prosthetic valve mold. The prosthetic valve mold is set to a first angle. The prosthetic valve mold is rotated at a first rotational velocity and a first layer of electrospun fibers is deposited on the prosthetic valve mold. The prosthetic valve mold is stopped and a frame is positioned over the first layer. The prosthetic valve mold is set to a second angle. The prosthetic valve mold is rotated at a second velocity and a second layer of electrospun fibers is deposited on an outer surface of the first layer and an outer surface of the frame.

Abstract: Described herein are methods and systems for forming metal interconnect layers (MILs) on engineered templates and transferring these MILs to device substrates. This “off-device” approach of forming MILs reduces the complexity and costs of the overall process, allows using semiconductor processes, and reduces the risk of damaging the device substrates. An engineered template is specially configured to release a MIL when the MIL is transferred to a device substrate. In some examples, the engineered template does not include barrier layers and/or adhesion layers. In some examples, the engineered template comprises a conductive portion to assist with selective electroplating. Furthermore, the same engineered template may be reused to form multiple MILs, having the same design. During the transfer, the engineered template and device substrate are stacked together and then separated while the MIL is transitioned from the engineered template to the device substrate.

Abstract: The invention provides a method for producing embedded contact lenses involving steps of use of a set of 3 mold halves in two-curing steps. One of the 3 mold halves have been used twice, the first time for molding an insert and the second time for molding the embedded hydrogel contact lens. The twice-used mold half has been treated with a corona plasma or a vacuum UV in a central circular area of its molding surface having a diameter equal to or smaller than the diameter of the insert to ensure that the molded insert consistently adhered to the twice-used mold half. The method also comprises a step of forming a reactive polysiloxane coating that is covalently attached onto the back or front surface of a molded insert adhered on the twice-used mold half before molding the embedded contact lens in the 2nd curing step.

Abstract: A method of creating a polymer surface with surface structures is disclosed. The method includes creating a mold, forming a metal sheet into the molds, creating a surface structure on a surface of the metal sheet by exposing the surface to laser pulses, and bringing a curable polymer to be in contact with the surface of the metal sheet containing the surface structure, curing the curable polymer, and separating the cured polymer from the metal sheet, resulting in a polymer surface containing the surface structure. The polymer surfaces with the surface structures can be hydrophobic or superhydrophobic depending on the micro and nano features contained by the surface structures.
