以十六烷基三甲基溴化铵(CAB)为模板剂，采用Sal-Gel法制备了形状可控的介孔生物活性玻璃。采用FE-SEM、透射电子显微镜、BET和BJH等方法对BGS的形貌、比表面积和孔径进行了表征。以十六烷基三甲基溴化铵(CTAB)为模板剂，制备了具有中孔结构和高比表面积的棒状BGS。随着CTAB浓度的增加，样品的成型过程呈现出一个由球形到短棒再到长棒的动态过程。本研究为BGS球状和杆状结构的控制提供了一种有效的途径。(C)2015爱思唯尔B.V.保留所有权利。
In this work, a facile method was developed for fabrication of mesoporous bioactive glasses (BGs) with controlled shapes using cetyltrimethylammonium bromide (CAB) as templating agent for sal-gel process. The morphologies, specific surface areas and pore sizes of the BGs were characterized by FE-SEM, TEM, and the BET and BJH methods, respectively. Rod-like BGs with mesoporous structures and high specific surface areas were prepared using CTAB as the templating agent. The shaping of the samples depicted a dynamic process from sphere to short rod then to long rod as the CTAB concentration was increased. This study presents an effective approach for controlling the spherical and rod-like structures of BGs. (C) 2015 Elsevier B.V. All rights reserved.
