Method of producing hollow silicone fine particles

摘要

There is interest in producing anti-reflective surfaces by a wet coating method. Methods of preparing hollow silica particles with a particle diameter of 0.1-300pm have been known for many years. However, hollow silica can easily break during a coating process or during use. Additionally the method of preparation is long with a large number of steps and the resulting particles have a wide particle size distribution.This patent describes a method of preparing hollow silicone fine particles with low breakability, a volume average particle diameter of less than 1pm and a narrow particle size distribution.
