摘要: 采用共沉淀法将防霉剂1, 2-苯丙异噻唑啉-3-酮(BIT)成功插入到Mg-Al层状双金属氢氧化物层间(LDH), 合成Mg2Al-BIT LDHs纳米杂化物。采用X射线衍射、傅里叶红外光谱、扫描电子显微镜进行表征。并在pH=4.8和7.2的介质中研究药物缓释动力学。结果显示BIT成功地插入到了LDH的层间, 载药量为44.35%, 释放动力学过程符合准二级动力学方程。将胶囊型防霉剂添加到醇酸树脂涂层中进行霉菌试验。结果表明Mg2Al-BIT LDHs在耐耗、溶出、析出方面优于BIT, 后期防霉效果更好。

Abstract: Mg-Al layered double hydroxides, loaded with 1,2-benzisothiazolin-3-ketone(Mg2Al-BIT LDH), were synthesized via coprecipitation method. The resulting compounds were characterized by X-ray diffraction, Fourier transform infrared spectroscope and scanning electron microscope. Drug release kinetics were studied in the medium with pH at 4.8 and 7.2. The results showed that BIT was successfully inserted into the LDH inter layers, with a drug loading rate of 44.35%。The release kinetics process was in line with the quasi-second-order equation. The results showed that the antifungal effects of BIT were worse than that of Mg2Al-BIT LDHs in the final phase of the mold test due to its consumption, dissolution and precipitation, suggesting Mg2Al-BIT LDHs nano-hybrid a better anti-mildew duration.

Key words: layered double hydroxides, BIT, sustained-release, anti-mildew duration
