2023年8月26日 · SiO 2-based MTMS combined with CTAB can modify the surface morphology of particles, reducing the contact between vapor and solids and increasing the contact between vapor and liquid. We investigated the impact of different concentrations of CTAB by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR ...

本研究中，SiO 2通过溶胶-凝胶法制备不同浓度的十六烷基三甲基溴化铵(CTAB) 0.75 wt%、1.5 wt%和2.25 wt%的MTMS前驱体，对疏水性表面进行改性和改善。 根据扫描电子显微镜 (SEM) 图像和 X 射线衍射 (XRD) 分别显示，随着 CTAB 的添加，颗粒尺寸变得更加广泛，并且峰值衍射 ...

2024年4月1日 · In this research, the impact of variations in the composition of MTMS:TEOS, when modified with a cetyltrimethylammonium bromide (CTAB) precursor, on silica characteristics was investigated. Furthermore, the best composition for brine desalination was identified.

2017年1月1日 · In this work, we describe the successful synthesis of super-hydrophobic polymethylsilsesquioxane (PMSQ) aerogels with a porous network by a sol-gel polymerization process using methyltrimethoxysilane (MTMS) reactants with the addition of cetyltrimethylammonium bromide (CTAB) surfactants.

2019年1月15日 · In this paper, using methyltrimethoxysilane (MTMS) as precursor, silica aerogels (SA) with excellent performance were synthesized within 10 h via APD without further surface modification and solvent exchange. The investigation was concentrated on three primary factors, including base catalyst, surfactant, and co-solvent system.

由甲基三甲氧基硅烷（mtms）和原硅酸四乙酯（teos）精心涂覆在氧化铝管上的二氧化硅基薄层膜，并用十六烷基三甲基溴化铵（ctab）进一步改性，随后用于盐水淡化。

本发明的CNF/MTMS/LG-CTAB-Citral抗菌复合气凝胶滤片尤其适用于低污染浓度下过滤空气中的细颗粒物以及室内外的生物气溶胶的过滤。

在这项工作中，我们描述了通过使用甲基三甲氧基硅烷（MTMS）反应物并添加十六烷基三甲基溴化铵（CTAB）表面活性剂的溶胶-凝胶聚合过程成功合成具有多孔网络的超疏水性聚甲基硅倍半氧烷（PMSQ）气凝胶。 针对不同数量的CTAB掺杂量，研究了CTAB改性的PMSQ气凝胶的比表面积，孔径和疏水性。 C / M摩尔比为0.001、0.002和0.004的原始和CTAB改性PMSQ气凝胶的比表面积分别为491、301、342和298 m 2 / g。 C / M摩尔比为0.001、0.002和0.004的CTAB改 …

2-based MTMS combined with CTAB can modify the surface morphology of particles, reducing the contact between vapor and solids and increas-ing the contact between vapor and liquid. We investigated the impact of different concentrations of CTAB by scanning electron microscope (SEM), X-ray diffraction (XRD),

2020年5月22日 · In this work, monolithic silica aerogels were prepared in pure water within 4 h by using MTMS as the precursor under ambient pressure drying (APD). The effects of the volume ratio of H2O/MTMS, CTAB content and NH3·H2O concentration on the properties of MTMS-based aerogels (MSA) were investigated experimentally.
