The cooperation between the cyclodextrin grafted onto the thermoplastic polymer and the polymer structure can provide barrier properties to a film, web or other polymer structure. A permeant or a contaminant can be complexed or trapped within the polymer and held within the film or Web preventing the permeant or contaminant from passing into the interior of a container or enclosure.Type: GrantFiled: May 5, 2006Date of Patent: October 20, 2009Assignee: Cellresin Technologies, LLCInventors: Willard E. Wood, Neil J. Beaverson, Kasyap V. Seethamraju

Publication number: 20090104523Abstract: A polymer that combines high ionic conductivity with the structural properties required for Li electrode stability is useful as a solid phase electrolyte for high energy density, high cycle life batteries that do not suffer from failures due to side reactions and dendrite growth on the Li electrodes, and other potential applications. The polymer electrolyte includes a linear block copolymer having a conductive linear polymer block with a molecular weight of at least 5000 Daltons, a structural linear polymer block with an elastic modulus in excess of 1×107 Pa and an ionic conductivity of at least 1×10?5 Scm?1. The electrolyte is made under dry conditions to achieve the noted characteristics. In another aspect, the electrolyte exhibits a conductivity drop when the temperature of electrolyte increases over a threshold temperature, thereby providing a shutoff mechanism for preventing thermal runaway in lithium battery cells.Type: ApplicationFiled: October 1, 2008Publication date: April 23, 2009Inventors: Scott Mullin, Ashoutosh Panday, Nitash Pervez Balsara, Mohit Singh, Hany Basam Eitouni, Enrique Daniel Gomez
