Abstract

Ferulic acid (FA), an organic UV absorber and free radical scavenger, was intercalated into an inorganic zinc basic salt (ZBS) matrix to prepare a UV screening material. FA molecules were vertically oriented bilayer in the ZBS lattice with an expansion of approximately 22.7 angstroms along the c-axis. The FA-ZBS nanohybrid exhibited a superior UV-A approximately UV-B screening ability and an antioxidant activity that was comparable to that of a pure FA molecule. The in vitro release test showed the biphasic release of the FA molecules from the FA-ZBS nanohybrid that consisted of an initial burst, followed by a slow and sustained release.

摘要

阿魏酸(FA)是一种有机紫外线吸收剂和自由基清除剂,被插入到无机碱式锌盐(ZBS)基质中以制备一种紫外线屏蔽材料。FA分子在ZBS晶格中呈垂直取向的双层结构,沿c轴方向膨胀约22.7埃。FA-ZBS纳米杂化物表现出优异的UV-A至UV-B屏蔽能力以及与纯FA分子相当的抗氧化活性。体外释放试验表明,FA分子从FA-ZBS纳米杂化物中呈双相释放,包括初始的突释,随后是缓慢而持续的释放。
