一种负载薄荷醇多孔高分子微球烟草香料缓释材料及其制备方法
摘要：
本发明涉及一种烟草香料缓释材料的制备方法，具体涉及一种负载薄荷醇多孔高分子微球烟草香料缓释材料及其制备方法。一种负载薄荷醇多孔高分子微球烟草香料缓释材料，由以下方法制得：将烟草香料薄荷醇溶解于溶剂中，加入多孔高分子微球材料搅拌溶解，去除溶剂后，得到负载薄荷醇多孔高分子微球烟草香料缓释材料。本发明将薄荷醇溶解在低沸点溶剂中，利用多孔高分子微球的纳米孔的毛细作用，使得薄荷醇在孔内富集并原位结晶形成纳米晶体，从而实现薄荷醇的负载；负载后的薄荷醇通过缓慢从孔内挥发，通过丰富孔道的限制扩散，实现薄荷醇的控制释放。
摘要（英）：

The invention relates to a preparation method of a tobacco spice slow-release material, and in particular relates to a menthol-loaded porous polymer microsphere tobacco spice slow-release material and a preparation method thereof. The preparation method of the menthol-loaded porous polymer microsphere tobacco spice slow-release material comprises the following steps: dissolving tobacco spice menthol in a solvent, and adding a porous polymer microsphere material into the solvent and dissolving in a stirring manner to remove the solvent, thereby obtaining the menthol-loaded porous polymer microsphere tobacco spice slow-release material. According to the method, the menthol is dissolved in the solvent with a low boiling point, so that the menthol is enriched in nanopores by utilizing the capillarity of the nanopores of porous polymer microspheres and is crystallized in situ so as to form a nanocrystal, and thus the loading of the menthol is realized; and the loaded menthol is volatilized from the nanopores in a slow-release manner, and the diffusion of the loaded menthol is limited by virtue of the abundant nanopores, so that the release of the menthol is controlled.
