Nano- and microstructured materials from fibrillated cellulose
Ph D Student: Andreas Fall
Fundamental characterization of colloidal stability and structural properties of nano cellulose fibrils and fibrillar networks.
A combination of imaging techniques, e.g. AFM, Cryo-TEM and SEM, will be used to get the complete understanding of the systems structural properties. With image analysis the results from all the imaging will be quantified in order to develop mathematical models describing the structural changes of fibrils and fibrillar networks as a function ionic strength, pH and fibril concentration. In addition electrostatic properties, such as surface charge and surface potential, will be measured and modulated. The combination of well described electrostatics and controllable structural properties will make it possible to design biomimetical, hierarchical designed, materials. These materials can be used for new advance products, e.g. light weight high strength products or control realize designed materials for medical delivery.
