Thermoelectric Properties of Ca3Co4O9/Polyaniline CompositesBin Zheng1,2,Yuanhua Lin2,Jinle Lan2,Xiaoping Yang11. State Key Laboratory of Organic-Inorganic Composites,Beijing University of Chemical...">Ca3Co4O9/polyaniline bulk composites have been successfully fabricated by ball-milling and hot-pressing method.Our results indicate that the Seebeck coefficient can be increased nearly by 400%with adding15 wt......
composites were obtained from the properties of a repeating unit cell that represents the woven fabric composites. Therefore, the elastic properties obtained from the stiffness matrix of a repeating unit cell were considered to be the bulk mechanical properties of the woven fabric composites. The identification of the relation between elastic properties and the stiffness matrix can be seen in Ref......
