Extended Maxwell Garnett Formalism for Composite Adhesives for Microwave-Assisted Adhesion of Polymer Surfaces

Adhesives with dielectric loss are needed for microwave-assisted joining of polymeric substances. The dielectric loss in an otherwise suitable adhesive may be en hanced by doping it with fine metallic particles. Here we use a recently extended Maxwell Garnett formalism to estimate the complex dielectric constant of a metal-doped composite adhesive, with specific focus on the imaginary part of the dielectric constant of the com posite adhesive.
