Abstract: Polymer electrolytes offer increased safety and stability as compared to liquid electrolytes, yet there are a number of new challenges that polymer electrolytes introduce. A polymer electrolyte, as disclosed herein, is a block copolymer that has a block that provides mechanical strength and a novel, ionically-conductive polymer block with a backbone that is both highly flexible and highly conductive with high conductivity pendant chains attached, thus increasing the concentration of lithium coordination sites and improving ionic conductivity. Previous strategies for comb-type conductive polymers have focused on attaching either conductive pendant chains to a flexible non-conductive backbone or conductive pendant groups to a marginally flexible conductive backbone.

Abstract: A platen cover for an imaging device such as a copier or scanner includes a substrate and at least of portion of the surface of the substrate is coated with a fluorescent coating. Preferably, the substrate has a dark or black color. The dark color of the substrate substantially reduces or eliminates show through of an image on the backside of an original document when the platen cover is not exposed to a light source for imaging. At the same time, when holes or uneven borders are present in the original document, the fluorescent coating fluoresces upon exposure to the light source at these regions of the original document, making these portions appear white in the replicated image and thereby substantially reducing or eliminating the unsightly appearance of these portions as black portions in the replicated image.
