Mixed Gas Transport Through Polymeric Materials and Composites

本项目的研究重点是制造和评估一种新的仪器来评估通过膜和复合膜的气体渗透性。一种新型的气体采样系统和设备的自动化将被检验，作为一种提供高精度分子传输数据的手段，其时间分辨率为秒级。计划的测试包括金属陶瓷、聚合物陶瓷和聚合物混合膜的研究。膜分离工艺是一种经济、节能的方法，有助于使美国工业更具竞争力和对环境负责。用于气体分离的新膜的发展和特性可以影响燃料工业的处理，控制挥发性有机化合物或温室气体的环境努力，以及医院供氧的空气分馏。

Research in this project will focus on the fabrication and evaluation of a new apparatus to assess gas permeabilities through membranes and composite membranes. A novel gas sampling system and automation of the equipment are to be examined as a means of providing high precision data of molecular transport with temporal resolution on the order of seconds. Planned tests include study of metal-ceramic, polymer-ceramic and polymer blend membranes. Membrane separation processes are economical, energy-efficient methods which help to make American industry more competitive and environmentally responsible. Development and characteristics of new membranes for gas separations can impact processing in the fuel industry, environmental efforts to control volatile organic compounds or greenhouse gases, and air fractionation for hospital oxygen supplies.
