| titleOfInvention | A kind of organic/inorganic double shell photochromic microcapsule and preparation method thereof |
| abstract | The invention discloses an organic/inorganic double-shell photochromic microcapsule and a preparation method thereof. The microcapsule comprises a wall material and a core material, and the wall material comprises a double layer composed of polymethyl methacrylate and tetraethyl orthosilicate. The wall material and the core material are photochromic materials. The preparation method of the above-mentioned microcapsules includes the following steps: (1) preparing a photochromic material; (2) mixing an organic wall material polymer, a hydroxyl-containing polymer and a photochromic material as an oil phase; (3) mixing the oil phase Homogeneous emulsification with the water phase to obtain an O/W emulsion; heating to volatilize the solvent in the emulsion to obtain a hydroxyl-containing microcapsule solution; (4) adding tetraethyl orthosilicate and a silane coupling agent to the hydroxyl-containing microcapsule solution (5) making the mixed solution alkaline, and stirring to obtain the microcapsules. The invention has the advantages of tight coating on the photochromic material, high fatigue resistance and strong practicability; the method is simple and efficient, the cost is low, the coating rate is high, and is suitable for industrialization. |
