AI Technical Summary
Existing methods for producing hollow particles with a silicone resin shell are complex, environmentally and economically disadvantageous due to the use of templates that require laborious removal and disposal, and the resulting particles are limited in their ability to absorb functional substances.
A method for producing hollow particles without a template, involving the condensation-crosslinking of a silicone resin composition at the interface of an emulsion stabilized by particulate solids, forming a shell that encapsulates optional ingredients and allows for controlled release.
The method produces hollow particles with an amphiphilic shell that can absorb and release functional substances, reducing environmental impact and production costs while enabling enhanced surface effects and lightweight filler properties.
