title: Single- and multicompartment hollow polyelectrolyte complex microcapsules by one-step spraying.
abstract: Polyelectrolyte complex microcapsules are prepared using 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 the polymer. The size and wall thickness of the microcapsules are precisely controlled. Encapsulation of polymers and nanoparticles by mixing them with polyelectrolyte solutions is demonstrated.
