Abstract:
Described herein are various polymer-covered glass and glass-ceramic articles that exhibit improved adhesion between the polymer and the glass or glass-ceramic, along with methods for their manufacture and use. The improved articles generally include a glass or glass-ceramic substrate, a surface-roughened coating disposed on at least a portion of an edge of the glass or glass-ceramic substrate, and a polymer covering disposed on at least a portion of the surface-roughened coating. The surface-roughened coatings beneficially allow the polymer coverings to adhere better to the edge surfaces of the glass or glass-ceramic substrates relative to similar or identical articles that lack the surface-roughened coating.

Abstract:
A flame retardant polymer composition is provided. The polymer composition includes a polymer resin and a flame retardant package dispersed within the polymer resin. The flame retardant package includes an additive of a polyoxometalate ionic liquid (PIL) and a synergist carrier. In particular, the PIL includes organic cations that produce an acid upon heating. Also, a flame retardant optical fiber cable is provided. The cable includes at least one optical fiber and a polymeric jacket that surrounds the at least one optical fiber. The polymeric jacket includes a polymer resin, a carbon source, an acid source, a polyoxometalate ionic liquid (PIL), and a synergist carrier. In particular, the PIL includes organic cations that produce an acid upon heating.
Abstract:
A method of making an antimicrobial composite article, including the steps: providing a matrix comprising a polymeric material; providing a plurality of second phase particles comprising an antimicrobial agent; melting the matrix to form a matrix melt; distributing the plurality of second phase particles in the matrix melt at a second phase volume fraction to form a composite melt; forming a composite article from the composite melt; and treating the composite article to form an antimicrobial composite article having an exterior surface comprising an exposed portion of the matrix and the plurality of second phase particles. The distributing step can employ an extrusion process. The forming a composite article step can employ an injection molding process. The treating step can employ abrading and plasma-treating the article to define the exterior surface.

Abstract:
An antimicrobial article that includes: an antimicrobial composite region that includes a matrix comprising a polymeric material, and a first plurality of particles within the matrix. The particles include a phase-separable glass with a copper-containing antimicrobial agent. The antimicrobial composite region can be a film containing the first plurality of particles that is subsequently laminated to a bulk element. The first plurality of particles can also be pressed into the film or a bulk element to define an antimicrobial composite region. An exposed surface portion of the antimicrobial composite region can exhibit at least a log 2 reduction in a concentration of at least one of Staphylococcus aureus, Enterobacter aerogenes, and Pseudomonas aeruginosa bacteria under a Modified EPA Copper Test Protocol.
