Negative magnetostrictive paper formed by dispersing CoFe(2)O(4) particles in cellulose nanofibrils

Polymers are often combined with magnetostrictive materials to enhance their toughness. This study reports a cellulose nanofibril (CNF)-based composite paper containing dispersed CoFe(2)O(4) particles (CNF–CoFe(2)O(4)). Besides imparting magnetization and magnetostriction, the incorporation of CoFe(...

Sumario:Polymers are often combined with magnetostrictive materials to enhance their toughness. This study reports a cellulose nanofibril (CNF)-based composite paper containing dispersed CoFe(2)O(4) particles (CNF–CoFe(2)O(4)). Besides imparting magnetization and magnetostriction, the incorporation of CoFe(2)O(4) particles decreased the ultimate tensile strength and increased the fracture elongation of the CNF–CoFe(2)O(4) composite paper. CNF was responsible for the tensile properties of CNF–CoFe(2)O(4) composite paper. Consequently, the magnetic and magnetostrictive properties and tensile properties of CNF–CoFe(2)O(4) composite paper can be controlled by changing the mixture ratio of CNF and CoFe(2)O(4) particles.
