Abstract
Polyelectrolyte complex microcapsules are prepared by a novel template- and surfactant-free method. The microcapsules are produced spontaneously by ultrasonically spraying a solution of complex into a hot water reservoir which enhances diffusion and relaxation of polymer. The size and wall thickness of microcapsules are precisely controlled. Encapsulation of polymers and nanoparticles by mixing them with polyelectrolyte solutions is demonstrated.
