Microencapsulation Using Electromagnetic Energy and Core and Shell Materials with Different Dielectric Constants and Dissipation Factors

Abstract: 

Methods of making microcapsules and microcapsules comprising a core material and a shell material with substantially different dielectric constants and dissipation factors. Exposure to appropriate electromagnetic energy selectively (a) heats the core material with the higher dielectric constant and dissipation factor, directly or indirectly fusing the shell material and forming microcapsules, or (b) hardens polymerized shell material, which has a high dielectric constant and dissipation factor.
