Investigation of Core-shell Polymer Structures with Application in Paint and Resin Industry

Many studies have been conducted on the synthesis, properties, and application of core-shell polymeric nanostructures. In this review, organic-organic and organic-inorganic core-shell structures, along with their synthesis techniques, have been investigated. The processes of making these structures include multi-stage seeded polymerization (including emulsion, miniemulsion, Microemulsion, Pickering emulsion, etc.), co-precipitation, and sol-gel. Among them, the emulsion polymerization strategies are the most paramount. Core-shell polymers are hybrid composite particles that have at least two different components. There are also parameters such as the kind and quantity of initiators, glass transition temperature (Tg</sub>), and crosslinks Density (CLD), which affect the morphology of particles. Soft or stiff core or shell, glass transition temperature, type of inorganic nanoparticles, and nanoparticle modifier can lead to different efficiencies for this type of core-shell polymer structure.
