Surface and shape modification effects on structural organization of magnetic nanoparticles in cellulose derivatives

Progress in additive manufacturing technologies during the last decade is intrinsically connected with developing and improving multifunctional inks. The modern era challenges raise additional requirements for ink formulations and printing processes, specifically for them being environmentally friendly, sustainable, and less expensive. One of the key properties affecting the performance of the printed sensors is the nanoparticles' distribution in the sensitive layer. In our current proposal, we continue our systematic research and aim to uncover the influence of particles' surface charge and shape anisotropy on the structural properties of both nano- and micro-thick films. The microfilm/support interface can be investigated using neutrons only, by directing the beam from the side of the silicon substrate (solid-solid mode). Thus, neutron reflectometry is an invaluable tool for probing morphology in the studied system.
