Water-Soluble Cellulose Derivatives as Suitable Matrices for Multifunctional Materials

This work reports on a simple and environmentally benign route to prepare freestanding magnetic films based on cellulose derivatives through the combination of cobalt ferrite (CoFe2O4) nanoparticles with methyl cellulose (MC), hydroxypropyl cellulose (HPC), and sodium carboxymethyl cellulose (NaCMC). Nanoparticles are able to “shield” hydrogen bonding interactions between polysaccharide chains and lower the viscosity of water-dissolved MC, HPC,...
