Abstract

The invention relates to a preparation method of anisotropic particles with variable morphology. The method comprises the following steps: firstly utilizing silanol hydrophilic groups produced by hydrolysis of a silane coupling agent to prepare a series of seeds with different hydrophilicities, then enabling the seeds to be swollen by monomers incompatible to the hydrophilic groups, and controlling the phase separation degree according to different phase separation degrees of polymers, which are induced by different interfacial tensions and incompatible to the hydrophilic groups so as to obtain the composite particles with the variable morphology. The composite particles contain organic-inorganic-organic phase non-spherical composite particles, which have an important significance for developing novel multi-component materials. The composite particles prepared by the preparation method disclosed by the invention are amphipathic, and can be used as compatibilizers, emulsifiers and the like for modifying mixtures of the incompatible polymers. The synthesis process is simple and easy to operate, clean, environment-friendly and easy to realize large-scale production; furthermore, the preparation method has universality and is suitable for other polymer systems which are mutually incompatible.
