Smart and tunable membranes from cellulose nanofibrils

Membranes are selective semi-permeable barriers, which are highly demanded in technological fields ranging from water purification to biosensors and analytics. Each membrane application has its own characteristic performance requirements, which makes tunable film materials particularly attractive. The outstanding characteristics of wood-based cellulose nanofibrils, such as high aspect ratio and strong film-forming tendency, make them intriguing materials for advanced membranes. As part of the international NanoSelect consortium, VTT has developed technologies that harness cellulose nanofibrils for the use of tunable nano-enhanced membrane materials.
