Montmorillonite (MMT), modified organically, was added as a nanofiller to increase their thermal and mechanical strength.

The XRD pattern of the hydrated TiO 2 /Mt composite sample (M-1T) showed that this material was completely disordered (Fig. 1), which may be due to the delamination of the montmorillonite layers...

2023年6月5日 · An atomic force microscope (AFM: Bruker, Karlsruhe, Germany) is used to measure the thickness and lateral diameters of the MMT nanosheets. X-ray diffraction (XRD: Empyrean, Bruker, Germany) equipped with Cu Kα radiation is used to characterize the interlayer spacing of the 2D MMT membranes.

A series of different weight% Mn-promoted Co nanoparticles were prepared and characterized by XRD, TPR, TGA, BET and SEM techniques. An increase in the surface area of MMT is observed...

2007年2月1日 · MMT has been identified as mainly smectite group minerals using X-ray diffraction (XRD) and FTIR analysis methods. XRD (Philips PW1140 model X-ray diffractometer) measurements were performed at room temperature on using Ni-filtered Cu-Kα radiation.

本文采用XRD对无机蒙脱土 (Na-MMT)及有机 蒙脱土 (1631-MMT、1831-MMT和D1827-MMT) 的层间距进行了测定，图1为蒙脱土的XRD图谱。 根据Bragg方程：2d sinθ=λ 式中d 为蒙脱土硅酸盐片层之间的平均距离即 (001) 面的距离，θ为半衍射角，λ为入射X-射线波长， λ=0.154nm。

using Cetyl trimethyl ammonium bromide (CTAB) and Sodium dodecyl sulfate (SDS) respectively. Basal spacing, presence of functional groups, Zeta-potential with particle size analysis and thermal stability of the Organomodified Na. MMT (OMMT) were characterized using XRD, FTIR, zeta-potential analyzer a.

2022年1月1日 · Microscopic crystals with soft phyllosilicate group of minerals which formed through precipitation of water solution, are called montmorillonite (MMT). It is concentrated and transformed by natural weathering in environment caves and left aluminosilicates which were contained in the bedrock.

Composites Due to its ease to use and availability, powder XRD is the most commonly used technique to study the degree of intercalation of surfactant and polymer chains into the two-dimensional...

2011年5月11日 · Basal spacing, presence of functional groups, Zetapotential with particle size analysis and thermal stability of the Organomodified Na-MMT (OMMT) were characterized using XRD, FTIR, zeta-potential analyzer and TGA respectively.
