In our research project, we explore novel ceramic materials, formed by a controlled heat treatment of silicon-based polymers, which contain microporosity in the size range below one nanometer, and which we anticipate to be applicable as materials for the separation of gases at high temperatures. The focus of our project is set on exploring the origin and collapse of microporosity in these materials, and to investigate how the pore structure affects the interaction of the materials with gases and gas mixtures.

To achieve our project objectives, we first clarify the impact of a wide range of process parameters on the polymer-to-ceramic transformation of the investigated materials, employing a combination of state-of-the-art and non-conventional techniques to unravel the chemical setup and composition as well as the micropore structure, some methods of which we develop and conduct in cooperation with national and international collaborators.
