▎ 摘  要

NOVELTY - Core-shell particle comprises a core containing a thermochromic material (TCM) and/or a phase-change material (PCM) and/or an additive material containing organic and/or polymeric material, an outer shell surrounding the core, and a material of the outer shell comprising a first metal oxide that contains a dopant. USE - The core-shell particle is useful for pigment used for coating. ADVANTAGE - The core-shell particles has the ability to change color due to the presence of the thermochromic dye in such products, and improves the adhesiveness in addition to its protection from the photodegradation process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a pigment comprising the core-shell particles; (2) a coating comprising the pigment and a binder material; (3) a method, involving mixing at least one fragment of a first material comprising TCM and/or PCM and/or additive auxiliary material with a surfactant in a solvent to form an emulsion precursor, where the additive material comprises an organic material and/or a polymeric material, combining the emulsion precursor with a second material that includes a first metal oxide with a dopant, and/or a metal oxide precursor, and to form an emulsion, and processing the emulsion to separate at least one core-shell particle in which the core is surrounded by the outer shell; and (4) a method for creating a layer of coating, involving forming a substantially liquidous material comprising the core-shell particles, and depositing the substantially liquid material onto a chosen substrate.
