“…It can be seen from Fig. 3 that organosmectites have two or three DTG peaks in the temperature range of 250-450 • C. The appearance of more than one DTG peaks points out that there were different locations of the HDTMA cations in the smectite structure [33,45]. Furthermore, the dehydroxylation temperature of organosmectites shifts to lower temperature with the higher HDTMA loadings compared to the raw smectite which may be explained by the easier loss of the hydroxyl units from the organosmectite [18,24,34].…”

“…12 demonstrates thermogravimetric analysis for montmorillonite with different CEC and alkyl chain length. Two types of anchorages were found on the longchain surfactant molecules of the organo-montmorillonite [121]. A significant amount of organics was weakly bonded to the montmorillonite surfaces via van der Waals forces with intercalated alkyl chains, and the other part was strongly confined within the interlayer space.…”

“…This study demonstrated the mobility difference of carbon atoms in the intercalated alkyl chain.Fig. 14illustrated the mass spectral analysis of the fragments of alkyltriphenyl phosphonium montmrillonite[121]. The thermal degradation pathway was deduced from the activation energy and DTA and thermogravimetry (TG) (%) curves of (a) wyoming montmorillonite and (b) wyoming montmorilloniteaminotriazole complex[134].…”

A B S T R A C TOver the years, the emergence of pesticides practice has prevailed to be the most intricate environmental turmoil amongst the scientific community. Specifically, pesticides constitute an accumulative, persistent and detrimental impact towards the survival of flora, fauna and environmental matrix. This has inspired a developing research with a variety of treatment technologies. Adsorption is recognized as the most efficient and promising approach, due to the ease of operation, simplicity of design, insensitivity to the toxic substances and superior capability for removing a broad range of pollutants. Its diverse applications, however, are retarded by the high cost of adsorbents and difficulties associated with regeneration. Montmorillonite and its derivatives, a unique group of under-utilized clay-based minerals has been proposed to be a suitable candidate for the treatment of contaminated wastewater. It plays a key role as the natural scavenger of pesticides, due to the abundantly availability, large specific surface area and high adsorptive and ion exchange properties. This paper describes the origin, physical, chemical and physicochemical properties of natural montmorillonite. The preparation procedure, reusability, commercial product and economical evaluation are highlighted. The specific classification, environmental and health implication of organo-pesticide are discussed. The revolution of montmorillonite-assisted adsorption process for the remediation of organo-pesticide was summarized. Additionally, the characterizations, surface chemistry and mechanism investigation are outlined.

“…The stacks can be dispersed in a polymer matrix as fillers/additives to form polymer/nanoclay composites, with applications such as mechanical strength enhancement, flame-resistance material, thickening and gelling agents, waste water treatment and gas permeability modification [12][13][14][15]. MMT nanoclay (2:1 layered silicates) with a high cation exchange capacity has cation exchange sites on the siloxane surface which can be combined with dissimilar substances, such as organic or biological molecules [16]. The MMT nanoclay stacks can be dispersed in a polymer matrix as fillers/additives to form polymer/nanoclay composites, which have been widely studied due to their high cation exchange capacity, swelling behavior, and large surface area [17][18][19].…”

Recent advancements in material technologies have promoted the development of various preparation strategies and applications of novel polymer–nanoclay composites. Innovative synthesis pathways have resulted in novel polymer–nanoclay composites with improved properties, which have been successfully incorporated in diverse fields such as aerospace, automobile, construction, petroleum, biomedical and wastewater treatment. These composites are recognized as promising advanced materials due to their superior properties, such as enhanced density, strength, relatively large surface areas, high elastic modulus, flame retardancy, and thermomechanical/optoelectronic/magnetic properties. The primary focus of this review is to deliver an up-to-date overview of polymer–nanoclay composites along with their synthesis routes and applications. The discussion highlights potential future directions for this emerging field of research.
