CTS - 9622473 Eva Marand Virginia Poly. Inst & State U. ABSTRACT The project deals with the development and characterization of polymer-ceramic composite membranes. A highly cross-linked titanate network will be incorporated into a polyimide matrix via in-situ polymerization of titanium alkoxide. The formation of hydrogen bonds in the composite enhances thermo-mechanical stability and may improve selectivity at higher temperature. Gas transport properties will be correlated to membrane fabrication properties. Thermal, spectroscopic and microscopic methods will be used to characterize the membranes in terms of stability, microstructure, fractional free volume and specific molecular interactions. Potential applications of the composite membranes include high-temperature gas separations and catalysis for chemical manufacturing.

CTS - 9622473 伊娃·马兰德弗吉尼亚理工大学。 Inst & State U. 摘要 该项目涉及聚合物陶瓷复合膜的开发和表征。 通过钛醇盐的原位聚合，高度交联的钛酸酯网络将被纳入聚酰亚胺基质中。 复合材料中氢键的形成增强了热机械稳定性，并可以提高较高温度下的选择性。 气体传输特性将与膜制造特性相关。 将使用热、光谱和显微方法来表征膜的稳定性、微观结构、自由体积分数和特定分子相互作用。 复合膜的潜在应用包括高温气体分离和化学制造催化。
