摘要/Abstract

摘要：

以聚苯乙烯(PS)微球为硬模板, 制备中空介孔二氧化硅纳米微球(HMSs), 通过在其表面安装双稳态准轮烷分子作为超分子纳米阀门, 实现对缓蚀剂分子苯骈三氮唑(BTA)的酸/碱双刺激的响应释放功效. 采用透射电子显微镜(TEM)、 X射线衍射(XRD)和比表面积分析等手段表征了HMSs的形貌和结构, 使用傅里叶红外光谱(FTIR)和热重分析(TGA)验证了HMSs表面功能化过程, 利用紫外-可见分光光度计(UV-Vis)实时监测缓蚀剂分子在不同pH值下的释放过程. 实验结果表明, 合成的HMSs呈单分散, 比表面积为1141.16 m²/g. 利用超分子自组装技术制得的智能纳米容器实现了在中性条件下“零释放”, 而在酸性或碱性条件下大量释放的效果.

Abstract:

Hollow mesoporous silica nanoparticles(HMSs) were prepared using polystyrene microspheres(PS) as hard templates. The supramolecular nanovalves in the form of bistable pseudorotaxane molecules were installed on the surface of the HMSs and achieved the acidic and basic dual stimuli-responsive release effects of corrosion inhibitor molecules, benzotriazole(BTA). The morphology and structure of HMSs were characte-rized by transmission electron microscope(TEM), X-ray diffraction assay(XRD), Brunauer-Emmett-Teller(BET) and Barrett-Joyner-Halenda(BJH) analyses. The surface functionalization of HMSs was demonstrated by Fourier transform infrared spectrometer(FTIR) and thermogravimetric analysis(TGA). The release performances of BTA at different pH values were monitored by UV-Vis spectrophotometer. The results showed that the HMSs were monodispersed nanospheres and the specific surface area was 1141.16 m²/g. The intelligent nanocontainers constructed by the supramolecular self-assembly technology realized “zero premature release” at neutral condition and remarkable release at acidic or alkaline conditions.

Key words: Hollow mesoporous silica nanoparticles, Nanovalve, Corrosion inhibitor, Acidic and alkaline stimuli-responsive
