Method for synthesizing hybrid core-shell microparticles comprising a silicon dioxide shell and a polymer core with controlled structure and surface area

摘要

A hybrid particulate comprising a polymer core and a shell at least partially surrounding the polymer core and comprising a silicon dioxide layer, characterized by an RF value, the RF value being an external surface area to which nitrogen is adsorbed, and The shell is defined as the ratio to the surface area that can be calculated from the arithmetic mean diameter of the hybrid particles regarded as a spherical sphere, and the shell is a smooth closed type in which the RF value of the shell is between 1 and 1.5, the RF value of the shell is Hybrid microparticles having a structure selected from a hill-shaped closed type which is between 1.51 and 3 or an open type which has a shell RF value of greater than 3.01.
