摘要
中空二氧化硅微球因其无毒、生物相容性好、特殊的形貌特征等优势,近年来成为科学家们研究的热点。本文浅析了中空二氧化硅微球的制备方法,即模板法、喷雾干燥法及其他方法,阐述了不同制备方法的过程并分析了各自的优缺点。中空二氧化硅微球因其具有良好的缓控释作用、保护催化剂活性、增强超声波回波信号的功能,目前在医学、催化及超声影像领域显示出了很好的应用前景。
In recent years,hollow silica microspheres have become a research hotpot for scientists due to their advantages of non-toxicity,good biocompatibility and special morphology.The preparation methods of hollow silica microspheres,including template method,spray drying method and other methods,were analyzed in this paper.The preparation methods were described and their advantages and disadvantages were analyzed.Hollow silica microspheres show good application prospects in the fields of medicine,catalysis and ultrasonic imaging because of their good slow-release effect,protection of catalyst activity and enhancement of ultrasonic echo signal.
