“…Similar behavior has been reported by Tian et al for PBS/organoclay composites that has been correlated with the surfactant concentration. It has been shown that for surfactant loading higher than 0.6 CEC, a significant decrease of the tensile strength was obtained as result of the aggregation of the excess surfactant molecules which limit the PBS’s plastic deformation and PBS–organoclay interactions …”

“…In these investigated systems, the nanoclay seems to retard the local lamellar crystallization growth probably by hindering the mobility of the amorphous phase. 15 , 28 Indeed, the establishment of strong interactions between the functional groups of PBS matrix and the intercalated/adsorbed surfactant molecules in the OMt nanofiller will lead to partial physical immobilization of the polymer chains on the surface of platelets, thus preventing their participation in the flow process and their crystallization. The retarding crystallization effect seems to be dominant for low clay loading reflecting the greater number of interacting sites, while for high clay content, this behavior will be attenuated by the nucleating effect of the silicate layers which enhance the crystallization rate of PBS.…”

“…It has been shown that for surfactant loading higher than 0.6 CEC, a significant decrease of the tensile strength was obtained as result of the aggregation of the excess surfactant molecules which limit the PBS's plastic deformation and PBS−organoclay interactions. 15 Regarding the ductility of PBS/OMt nanocomposites, a slight decrease of hybrid's elongation at break was noticed with respect to neat PBS and particularly for high organoclay loadings This trend observed in the case of others filled polymer composites 34−36 is mainly attributed to the shrinkage of the cross-section of polymer resisting to deformation due to the addition of nanofillers. The polymer/OMt interface will constitutes a weakness region inducing early break.…”

“…An ideal balance between thermal and mechanical properties was achieved at a surfactant quantity equivalent to 0.6 times the CEC. 15 Recently, Karakehya et al investigated the effect of hexadecyltrimethylammonium bromide modified clay (OMt), nanocrystalline cellulose (NCC), and carbon nanofiber (CNF) reinforcements on the mechanical, thermal, and surface properties of PBS nanocomposites. Among the studied nanocomposites, PBS-OMt showed the highest hydrophobicity and the best mechanical properties as well as a significant increase in hardness and modulus.…”

Biocomposites based on biodegradable polybutylene succinate (PBS) and organomodified clays (OMt) were prepared by melt blending process. The OMt nanofillers were obtained by ion exchange reaction between sodium montmorillonite (Mt) and gemini surfactants bearing 4-decyloxyphenylacetamide hydrophobic chains and ethylene or hexylene spacer. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and rheological measurement results showed that the investigated hybrids present a uniform dispersion with an exfoliation of clay into the PBS matrix, particularly for short spacer surfactant based composites. The effect of organoclay loading and composition on the thermal, mechanical, and barrier properties was also investigated. High clay loading and long gemini surfactant spacer lead to substantial improvement of Young modulus values by 21%, while low clay content induces a reduction of the hybrid’s crystallinity due to strong OMt–PBS interactions. Compared to that of the neat PBS film, a significant reduction of the water vapor permeability (WVP) by 28% was obtained by adding only 3 wt % of PBS/OMt (2) which opens up prospects for this material in the field of food packaging. This study shows that gemini surfactant-modified organoclays can be used as effective nanofillers in a PBS matrix to access to value-added nanocomposites.

The most potent and significant polyphenolic molecule from tea catechins is epigallocatechin gallate (EGCG); it has potential anti-cancer and anti-inflammatory properties. Methods are needed to mitigate its presence in the environment and protect humans from exposure. The objective of the present study was to investigate a functionalized, low-cost clay mineral as an adsorbent for the tea polyphenol EGCG. Hydrophilic bentonite (Bn) was functionalized using Aliquat 336 (A336) and isobutyl(trimethoxy)silane (IBTS). The degree of clay functionalization depended on the extent of introduction of alkyl linkages between the superimposed clay layers. Results revealed that Aliquat 336 functionalized clay (A336-Bn) exhibited maximum thermal stability at 500°C and it is a promising adsorbent for ECGC with a maximum adsorption capacity of 196.26 mg/g at equilibrium. Experimental data were analyzed using pseudo-first order and pseudo-second order models. Adsorption isotherms were interpreted from the Freundlich adsorption isotherm.
