Waterborne polyurethanes (WBPUs) do not require theuse of organic volatile compounds for its dispersion,therefore they stand as a green alternative forreplacing traditionally used polyurethanes dispersed inorganic volatile solvents. However, their lowerthermal stability, and mechanical performance incomparison with those of solvent based-PUformulations have lead to the search for new strategiesto modify and improve these properties. In this sense,nanoparticles and specifically, those who are sensitiveto an external magnetic field are part of a newgeneration of materials with varied potentialapplications. The aim of this work, is to investigate thenanostructure and resulting properties of magneticnanocomposites prepared from a polycaprolactone(PCL) based WBPU loaded with magnetitenanoparticles (MNPs).
