CelPorMat

Development of microfibrillated cellulose-based porous materials in consideration of industrial relevant processes.

The objective of this project is to engineer cellulose-based porous materials, which can be used for various sorption applications for liquids. By tailoring the porosity and surface chemistry of these novel three-dimensional cellulosic structures, the hydrophilicity and oleophilicity of the final product will be tuned and optimized. The development and engineering of the sorbents take place with regard to industrial relevant processes and scalability.
