Thermal Conductivity of Composites of Core-Shell Particles
Composite materials consisting of core-shell particles randomly distributed in a continuous medium (matrix) are of importance in many industrial applications [1-5]. The core-shell-type particles consist of a homogeneous core surrounded by a homogeneous shell of a different material. The encapsulation of core with shell is desirable for many reasons: to improve the thermal and/or mechanical properties, to modify the surface properties of particles, and to improve the dispersibility of particles in the matrix. One practical example of composites of core-shell-type particles is “syntactic foam” . Syntactic foam consists of core-shell particles with gas core and glass shell (hollow glass microspheres) dispersed in a plastic resin.
