“…Independently measured surface potentials (or charge densities) and Hamaker constants agreed with AFM results. At separations below 1-5 nm differences occurred (see for instance [16,432,453,454]), particularly at high ionic strength. These are usually attributed to hydration forces.…”

“…The results showed that a strong repulsive interaction exists at short distances (below 2 nm), which decayed exponentially with the distance between the particles, and the long-range double layer repulsion is negligible. Other studies on the determination of surface forces between silica surfaces by SFA and AFM suggested that hydration force was responsible for the non-DLVO short-range forces between particles (Meagher, 1992;Yoon et al, 1998). The overlapping of the hydration layers of two interacting surfaces causes an increase in the free energy of the system, provoking the short-range hydration repulsion.…”

Hydration layer on clay mineral surfaces is originated from the adsorption of polar water molecules and hydrated cations on the surfaces through unsaturated ionic bonds, hydrogen bonds and van der Waals bonds. It has attracted great attentions because of their important influences on the dispersive stability of the particles in aqueous solutions. This review highlighted the molecular structure of clay minerals, the origin of hydration layers on clay mineral surfaces, the hydration layer structural model, hydration force and the main parameters of affecting the hydration layers on clay minerals (crystal structure, cationic type and strength, and solution pH). Also, the research methods for hydration layers were briefly described, especially the determination of hydration layer thickness by the Einstein viscosity method and AFM method. In addition, the applications of the stability of fine clay mineral particles in aqueous suspensions were summarized.Keywords: Hydration layers; clay minerals; dispersion; hydration force Warstwa uwodniona na powierzchni minerałów ilastych (gliniastych) powstaje w wyniku adsorpcji polarnych cząsteczek wody i uwodnionych kationów powierzchniowych wiązanych za pomocą nienasyconych wiązań jonowych, wiązań wodorowych i wiązań van der Waalsa. Zagadnienie to wzbudza wiele uwagi ze względu na to, że w dużej mierze warunkuje stabilność dyspersyjną cząstek w roztworach wodnych. W pracy omówiono strukturę molekularną minerałów ilastych, powstawanie warstw uwodnionych na powierzchni minerałów ilastych i siły hydratacji; przedstawiono także model strukturalny warstwy uwodnionej oraz główne parametry warunkujące powstawanie warstwy uwodnionej na powierzchni materiałów ilastych (struktura krystaliczna, rodzaj występujących kationów, stężenie roztworu i jego pH). Ponadto, pokrótce przedstawiono metody badań, ze szczególnym uwzględnieniem badania grubości warstw uwodnionych przy zastosowaniu modelu lepkości Einsteina oraz metody AFM. Ponadto, zestawiono zagadnienia związane ze stabilnością cząstek drobnoziarnistych minerałowa ilastych i ich potencjalne zastosowania.Słowa kluczowe: warstwy uwodnione, minerały ilaste, dyspersja, siła hydratacji

“…5. On the other hand the addition of alcohol removes the hydration repulsion (Yoon and Vivek, 1998), which is likely due to the adsorption of alcohol molecules displacing the first layer of water on the hydroxylated silica surfaces. Although the hydration force is a very short-ranged force, it has a significant influence on the bulk stability of suspensions, particularly in the case of nanoparticles.…”

The stability of particle suspensions, which is important in numerous industrial processes, is generally dominated by the interaction forces between the suspended particles. Understanding the interaction forces between surfaces in liquids is therefore fundamentally important in order to evaluate and control how particulates, including fluid droplets in emulsions and air bubbles in foams, behave in various systems. The invention of the surface force apparatus (SFA) enabled the direct measurement of interaction forces in liquids with molecular level resolution and it has led to remarkable progress in understanding surface forces in detail. Following the SFA, the application of atomic force microscopy (AFM) to force measurement has further extended the possibility of force measurements to a broad field of research, mainly due to the range of materials that can be employed. This review provides an overview of developments in the investigation of interaction forces between surfaces using AFM. The properties of various interaction forces, important in particle technology, revealed by the studies using AFM are described in detail.
