摘要: The present disclosure provides insulated electrical conductors, e.g., wires, and methods for producing such insulated electrical conductors to combat partial discharge by enhancing bond strength between the electrical conductor and a base insulating thermoplastic layer (e.g., including a PAEK). Such insulated electrical conductors can include: an electrical conductor; an insulating coating on at least a portion of a surface of the electrical conductor; and an oxide layer between the electrical conductor and the insulating coating. Methods for producing such insulated electrical conductors can involve extrusion of an insulating polymer onto the electrical conductor under ambient atmosphere and a subsequent heat treatment step, which can also be conducted under ambient atmosphere.

摘要: Methods for preparing oriented polymer tubes, such as biodegradable polymer tubes suitable for in vivo use, are provided herein. The disclosed methods provide alternatives to the typical extrusion/expansion methods by which oriented polymeric tubes for such uses are commonly produced. Advantageously, the disclosed methods can provide more homogeneous molecular orientation of crystallizable polymers within the tube walls, which can endow such polymeric tubes with enhanced strength (e.g., resistance to compression) and toughness.

摘要: Polymeric coated optical elements are described herein, which exhibit good optical properties, e.g., low attenuation. Some such coated optical elements comprise an optical element (e.g., an optical fiber) having an outer surface and a thermoplastic polymeric tight buffer coating on at least a portion of the outer surface of the optical element, wherein the polymer-coated optical element exhibits a first attenuation at room temperature of plus or minus about 50% the attenuation of a comparable optical element with no thermoplastic polymeric tight buffer coating thereon, and a second attenuation at room temperature after thermal cycling to a temperature of at least 170° C. that is about 2 times the first attenuation or less.

摘要: A heat shrink tubing, which can be readily peeled in the longitudinal direction after use (e.g., to remove the heat shrink tubing from an underlying material) is provided herein. The heat shrink tubing can be of various compositions, and generally is produced from at least one fluorinated, copolymeric resin. The tubing can exhibit desirable physical properties such as good optical clarity (e.g., translucency or transparency) and/or peelability, exhibiting one or more of complete, straight, and even peeling along a given length of tubing.

摘要: An improved process for forming a PTFE mat is described. The process includes providing a dispersion with PTFE, a fiberizing polymer and a solvent wherein said dispersion has a viscosity of at least 50,000 cP. An apparatus is provided which comprises a charge source and a target a distance from the charge source. A voltage source is provided which creates a first charge at the charge source and an opposing charge at the target. The dispersion is electrostatically charged by contact with the charge source. The electrostatically charged dispersion is collected on the target to form a mat precursor which is heated to remove the solvent and the fiberizing polymer thereby forming the PTFE mat.

摘要: A method of preparing antimicrobial-containing polymeric products is provided, the method involving electrospinning a dispersion comprising a dispersible polymer, a fiberizing polymer, and one or more antimicrobial agents. The electrospun material is heated to remove solvent and the fiberizing polymer, giving a nonwoven polymeric material having antimicrobial agent incorporated therein.
