Self-assembling polymer particle release system
Self-assembly is defined as the ability of an active ingredient (AI), when mixed with a polymer or polymers (solid or liquid state), to form either a complex or a strong attraction with the polymer/polymers, which influences the controlled release of the total system. This AI-polymer interaction or strong attraction can form in the solid state or in solution. The AI-polymer interaction also can form when applied to a filter paper, soil, seeds, or plant vegetation substrates, where the AI and polymer self-assembles into an AI-polymer-substrate matrix or complex that influences how the AI releases from the complex or matrix in a controlled manner.

Method of producing hollow particles, method of producing antireflection coating, and method of producing optical element
The present invention provides a method of producing hollow particles for reducing light scattering in an antireflection coating. This method includes synthesizing core-shell particles including a core containing an organic compound as a major component and a shell containing an inorganic-based compound as a major component in an aqueous medium, dispersing the core-shell particles in an organic solvent, and preparing hollow particles by heating the core-shell particles dispersed in the organic solvent to remove the core therefrom.
