One-pot preparation of micrometer-sized monodispersed silicone hollow particles

Abstract Micron-sized, monodispersed silicone hollow particles are functional materials with properties attributed to both their hollow structure and the silicone composition. However, there are few reports on their preparation. We have successfully prepared these particles by combining an original suspension polymerization technique, the self-assembling phase separated polymer (SaPSeP) method, with a molecular diffusion method. The resulting particles exhibit heat resistance owing to the silicone matrix and maintain their hollow structure even after heating to 900°C.
