Magnetic nanopaper

This project is focused on production and development of magnetic nanopaper with ferrimagnetic properties. Cellulose nanofibrils (CNFs) are used as a stiff and strong matrix of natural origin, while ferrimagnatic nanoparticles of SrFe12O19 are added to bring in the functionality. Nanopaper is prepared by spray coating technique which is simple to handle and to upscale. By manipulation of electrostatic interactions between CNF and magnetic nanoparticles (MNP) through pH and concentration variation we were able to successfully stabilize MNP in CNF network, which resulted in achieving the best magnetic performance by simple mixing of 2 components.
