合成了层状氢氧化锌(ZHN)，并将其与3种不同阴离子的商品有机紫外线(UV)吸收剂2-巯基苯甲酸、2-氨基苯甲酸和4-氨基苯甲酸进行了局部交换。用X射线粉末衍射(XRPD)、傅里叶变换红外光谱(FTIR)、紫外可见光谱(UV-Vis)和热分析(TGA、DTA)对交换反应进行了表征。在所有的阴离子交换产物中，都有有机物种接枝到无机基质上的证据。总的来说，插层/接枝后，相对于母体有机材料的使用，紫外吸收能力有所提高，这表明层状氢氧化盐(LHS)可以作为良好的替代基质来固定化妆品中具有紫外线阻隔性能的有机物种。
Layered zinc hydroxide nitrate (ZHN) was synthesized and nitrate ions were topotactically exchanged with three different anionic species of commercial organic ultraviolet (UV) ray absorbers: 2-mercaptobenzoic acid, 2-aminobenzoic acid, and 4-aminobenzoic acid. The exchange reactions were confirmed by X-ray powder diffraction (XRPD), Fourier transform infrared spectroscopy (FTIR), ultraviolet visible (UV–Vis) spectroscopy, and thermal analysis (thermogravimetry, TGA, and differential thermal analysis, DTA). In all the anionic exchanged products, evidence of grafting of the organic species onto the inorganic matrix was obtained. In general, after intercalation/grafting, the UV absorption ability was improved in relation to the use of the parent organic material, showing that layered hydroxide salts (LHS) can be good alternative matrixes for the immobilization of organic species with UV-blocking properties in cosmetic products.
