Thermal Analysis of Polyimide-Cobalt Ferrite Nanocomposites

Mazuera D., Perales-Perez O., Singh S.P., Suarez O.M., University of Puerto Rico-Mayagüez, PR

Thermal stability and thermomechanical behavior of new polymer-based nanocomposite was investigated to assess the viability of the fabrication process. The nanocomposite film consisted of a polyimide (PI) matrix and nanodispersoids of a recently developed high-coercivity [...]

Preparation and Characterization of Polyimide-Cobalt Ferrite Nanocomposite

Mazuera D., Cedeño Y., Perales-Perez O., Singh S.P., University of Puerto Rico-Mayagüez, PR

Synthesized 20 nm cobalt ferrite single crystals, which exhibited a coercivity of 2.9kOe at room-temperature, were dispersed in precursor polyamic acid at different volume fractions and cured at 300oC to develop the polyimide matrix. Polyamic [...]
