“…The literature also abounds with studies of the influence of mechanical processes on the structural and physico-chemical properties of a variety of clay minerals (Suray et al, 1997;Baudet et al, 1999;Sanchez-Soto et al, 2000;Frost et al, 2001;Franco et al, 2004;Dellisanti and Valdré, 2005;Hrachová et al, 2007;Vertuccio et al, 2009). The rapid development of the new, composite claybased materials has advanced the research and processing of fine-milling and reinforcing methods.…”

The present study broadened the research on the effect of the intensive physical disintegration of clay minerals (kaolinite and "Otay" montmorillonite) and mica (ripidolite), carried out by high-energy ball milling (HEBM), on their surface physicochemical characteristics, i.e., the specific surface area (SSA), the cation exchange capacity (CEC), and the electrokinetic properties. The mechanical disintegration of clay minerals occurred in two consecutive processes. Significant changes of the size, morphology and structure were followed by the change of the physico-chemical properties. The decrease of the particle size of the clay minerals resulted in significant increases in the SSA and CEC values, and in the exposure of new, amphoteric surfaces, significantly changing the electrophoretic mobility (EPM).Prolonged milling produced amorphous alumina-silicate aggregates. These solids exhibited the same morphological properties, SSA and CEC, despite the fact that they were formed from initially different clay minerals. In contrast, the electrophoretic mobility of these samples was significantly changed, exemplifying the significance of the initial chemical composition and the formation of different types of surface structures on the physico-chemical processes at amorphous solid-surface-liquid interfaces.

“…Table 2 presents the viscosity obtained on six samples. Table 2 shows an observable change in viscosity with the nature of organoclay additives [16]. No difference in viscosity between the parent paint (Batch 1) and Bent.DL-1 (Na) added antifouling paint (Batch No.…”

“…In various parts of the SEM photographs of Bent.DL-4, the grain boundaries steadily vanished. These changes in the morphologies and particle sizes are associated with the intercalation and adsorption of surfactant molecules [16]. In order to shed light on the microscopic structure of clay mineral, SEM coupled with an EDX provides a semi-quantitative elemental analysis of the solid surface.…”

“…2) was observed ( Table 2). The viscosity gradually increases with increasing the amount of CTAB in the montmorillonite layers [14,16]. This is explained by the possibility that the organoclay pillared by surfactant molecules with a long alkyl chain has enhanced an interaction between clay embodiment and the paint-polymer structure.…”

“…In other words, the presence of long alkyl chains in montmorillonite layers makes the organoclays become more compatible with the polymer molecules [17]. Therefore, an introduction of organoclay additives into antifouling paint has some significant effects on the mechanical properties of the parent paint [16,17].…”

Di Linh (Lam Dong Province, Vietnam) clay was chemically treated and pillared by cetyltrimethyl ammonium bromide (CTAB) surfactant under different preparation conditions. The synthesized organoclays were characterized by XRD, FT-IR, SEM, TEM, BET…techniques. The insertion of CTAB into the treated Di Linh clay leads to a significantly increased basal spacing. These pillared clays were further used as a paint additive. The preliminary results indicated that the presence of such an additive has a significant improvement of the mechanical properties of the organoclay-added paint.
