Though the market for synthetic membranes is growing toward 2.7 billion dollars in the next decade, there is an absence of technology for in situ characterization of the pore structure of thin film membranes. This is slowing progress in membrane development, limiting understanding of membrane function, and causing higher costs to develop and manufacture membranes. TPL proposes a sensor system able to make measurements on thin films that have exactly the same characteristics as finished membranes. The sensor will be based on a miniature, solid state, SAW device with mass sensitivity of 10-12g. During Phase I, mesoporous, microporous, nonporous and closed porous thin films will be evaluated. At constant temperature, the response of the sensor to absorption of gas by the thin film, and the pressure of a gas as it interacts with the film will permit detailed assessment of membrane function not possible with current techniques. TPL and its collaborators have substantial experience in the development of sensors and instrumentation systems, and in measuring porosity characteristics of both thin films and powders. The vast improvement in analytical capability achieved with the new system will result in new, less expensive membranes for many applications in the fields of biotechnology and medicine. PROPOSED COMMERCIAL APPLICATION Membrane development and manufacture, hermetic seals, medical and biotechnology products.

尽管合成膜的市场正在向27亿美元增长， 在未来十年，没有技术可以在 薄膜膜孔结构的原位表征。 这减缓了膜发育的进展，限制了对 膜功能，并导致更高的成本开发和 制造膜。 TPL提出了一种能够对薄膜进行测量的传感器系统 与成品膜具有完全相同的特性。 的 传感器将基于一个微型，固态，声表面波器件与质量 灵敏度10- 12 g。 在第一阶段，介孔、微孔、无孔和闭孔 将评价薄膜。 在恒定温度下， 该传感器通过薄膜吸收气体，并且 当气体与膜相互作用时， 膜功能不可能与目前的技术。 TPL及其合作者在开发方面拥有丰富的经验 传感器和仪器系统，以及测量孔隙度 薄膜和粉末的特性。 巨大的进步 新系统的分析能力将导致 新的，更便宜的膜，用于许多领域的应用， 生物技术和医学。 建议的商业应用 膜开发和制造，密封，医疗和 生物技术产品。
