Interlayer expansion of dimethyl ditallowylammonium montmorillonite as a function of 2-chloroaniline adsorption

Expansion characteristics of organo montmorillonites during the intercalation, aging, drying and rehydration processes: Effect of surfactant/CEC ratio

“…However, structural information of the OMt in this research was based on their dry samples, and whether organic cations will remain the same arrangement model in water was not shown. Similar question may also arise in many other investigations, and the structural information of the dry OMt rather than wet samples has been used to correlate the structural-sorptive characteristics [19][20][21][22]. Considering the expandable characteristics of OMt, they may have a quite different structure after the saturation with water.…”

“…The structural characteristics, such as basal spacing, surface area, porous structure and arrangement models of organic cations, have been reported in numerous publications [7][8][9][10][11][12][13][14][15][16]. Based on the obtained structural information, the potential correlation between microstructure and adsorption characteristics of organoclays has been proposed in several reports [1,[17][18][19][20][21][22]. Chen et al [5] indicated that as the arrangement model of organic cations evolves from flat-monolayer to flat-bilayer, to pseudo-trilayer, then to paraffin-monolayer and finally to paraffin-bilayer with the increase of their loading amounts, the alkyl chains will first form strong adsorbed organic film and then gradually transfer to weak partition organic phase.…”

Eco-friendly Polymer Nanocomposites

“…Among these reinforcements, the use of montmorillonites and bentonites is interesting because added to their environmental and economic importance (Zampori et al 2008), their natural abundance and their mechanical and chemical resistance makes them very useful as polymeric material reinforcements.
