摘要： A poly(phenylene) compound of copolymers that can be prepared with either random or multiblock structures where a first polymer has a repeat unit with a structure of four sequentially connected phenyl rings with a total of 2 pendant phenyl groups and 4 pendant tolyl groups and the second polymer has a repeat unit with a structure of four sequentially connected phenyl rings with a total of 6 pendant phenyl groups. The second polymer has chemical groups attached to some of the pendant phenyl groups selected from CH3, CH2Br, and CH2N(CH3)3Br groups. When at least one group is CH2N(CH3)3Br, the material functions as an anion exchange membrane.

摘要： A portable, non-cryogenic, oxygen generation system capable of delivering oxygen gas at purities greater than 98% and flow rates of 15 L/min or more is described. The system consists of two major components. The first component is a high efficiency membrane capable of separating argon and a portion of the nitrogen content from air, yielding an oxygen-enriched permeate flow. This is then fed to the second component, a pressure swing adsorption (PSA) unit utilizing a commercially available, but specifically formulated zeolite compound to remove the remainder of the nitrogen from the flow. The system is a unique gas separation system that can operate at ambient temperatures, for producing high purity oxygen for various applications (medical, refining, chemical production, enhanced combustion, fuel cells, etc . . . ) and represents a significant advance compared to current technologies.

摘要： A new class of hybrid organic-inorganic materials, and methods of synthesis, that can be used as a proton exchange membrane in a direct methanol fuel cell. In contrast with Nafion® PEM materials, which have random sulfonation, the new class of materials have ordered sulfonation achieved through self-assembly of alternating polyimide segments of different molecular weights comprising, for example, highly sulfonated hydrophilic PDA-DASA polyimide segment alternating with an unsulfonated hydrophobic 6FDA-DAS polyimide segment. An inorganic phase, e.g., 0.5–5 wt % TEOS, can be incorporated in the sulfonated polyimide copolymer to further improve its properties. The new materials exhibit reduced swelling when exposed to water, increased thermal stability, and decreased O2 and H2 gas permeability, while retaining proton conductivities similar to Nafion®. These improved properties may allow direct methanol fuel cells to operate at higher temperatures and with higher efficiencies due to reduced methanol crossover.
摘要翻译： 一类新型有机 - 无机混合物和合成方法，可用作直接甲醇燃料电池中的质子交换膜。 与具有随机磺化的NafionPEM材料相反，新类别的材料已经通过自组装实现了不同分子量的交替聚酰亚胺片段的磺化，其包括例如高度磺化的亲水性PDA-DASA聚酰亚胺片段交替 与未磺化的疏水性6FDA-DAS聚酰亚胺片段。 无机相，例如0.5-5重量％的TEOS可以引入到磺化聚酰亚胺共聚物中以进一步改善其性能。 新材料在暴露于水时表现出减小的膨胀，增加的热稳定性和降低的O 2和H 2气体渗透性，同时保持类似于Nafion的质子电导率。 这些改进的性能可以允许直接甲醇燃料电池在更高的温度下运行，并且由于降低的甲醇交换而具有更高的效率。
