“…The inorganic cations in the interlayer space of Sap, that compensate the negatively charged layer, can be exchanged with positively charged organic cations. Such cations can be formed from surfactants, dye or organometallic complexes in water (Kurokawa et al, 2014;Seki et al, 2015;Sas et al, 2017 Kurokawa et al, 2014). The surface of Sap is usually hydrophilic and the inorganic cations in the interlayer space tend to be hydrated (Ferrage, 2016).…”

“…Organic dye cations generally tend to aggregate on the surface of Sap, due largely to the hydrophobic interaction and van der Waals force between organic species (Konno et al, 2014;Donauerová et al, 2015;Matejdes et al, 2017;Sas et al, 2017;Tokieda et al, 2017). The aggregates are categorized into two types: H-aggregates and J-aggregates.…”

“…The idea of Sap/polymer nanocomposites might be borrowed from the Mt /polymer nanocomposites (Lambert and Bergaya, 2013). Similarly, the preparation of Sap/polymer nanocomposites is also achieved by solution intercalation (Jairam et al, 2013;Shin et al, 2013;Yang et al, 2013;Chang et al, 2014;Wu et al, 2014;Wang et al, 2015;Xi et al, 2015;Ju and Chang, 2016;Eguchi et al, 2017;Sas et al, 2017), melt mixing or melt intercalation (Zhen et al, 2012;Kitajima et al, 2013;Zhen and Wang, 2016) or in situ polymerization (Jairam et al, 2013;Nakamura and Ogawa, 2013; Tong and Deng, 2013; Bandla et al, 2017) ( Table 3). Melt mixing is the simplest method since it is easily operated, economic and environmental friendly (Shen et al, 2002;Pandey et al, 2005;Zou et al, 2008).…”

“…Taking advantage of the swellability of Sap (Ferrage et al, 2010;Dazas et al, 2015;Ferrage, 2016), researchers can introduce functional guest molecules into the structure of Sap and thus tune porosity, acidity and other physical and chemical properties. Many types of Sap-based hybrids or composites have been successfully prepared by the intercalation of bulky organic (Kurokawa et al, 2014;Marcal et al, 2015;Sas et al, 2017) and inorganic (Franco et al, 2016b;Miyagawa et al, 2017) cationic species, neutral polar molecules (Marcal et al, 2015) and polymers (Mishchenko et al, 2016;Eguchi et al, 2017) into the interlayer space of Sap. Covalent grafting of a moiety of organic molecules onto the surface of Sap proves feasible.…”

Modification of saponite (Sap) by surface engineering and intercalation chemistry introduces guest species into the structure of Sap and enhances the functionalities of the resultant Sap-based hybrids or composites. This review summarizes and evaluates latest scientific advances in the strategies for surface engineering, intercalation and hybridization of Sap, the insights into the relevant mechanisms, and the properties and applications of the resultant Sap-based materials. Studies have indicated that Sap can be inorganically modified by acid activation, inorganic cation exchange, pillaring, and adsorption. The methods of preparing organo-saponite (OSap) hybrids can be categorized as follows: 1) exchanging the inorganic cations in the interlayer space of Sap with organic cations; 2) covalent grafting of organic moieties or groups onto the surface of Sap; 3) intercalating polymer into the interlayer space of Sap by solution intercalation, and melt mixing or in situ polymerization. Organic-inorganic modified Sap can be made through the reactions between organic species and inorganic-modified Sap, or by the combination of inorganic species with organic-modified Sap. Modified Sap exhibits exceptional thermal stability, surface acidity, optical effects and adsorption. As such, the modified Sap can be used for optical materials, adsorbents, catalysts and clay/polymer nanocomposites (CPN). Literature survey suggests that future studies should place emphasis on optimizing and scaling up the modification of Sap, probing the thermodynamics, kinetics and mechanisms of the modification of Sap, endowing Sap with novel functionalities, and accordingly advancing the practical applications of the resultant Sap-based materials.

“…Among the existing luminescent materials (also known as luminophores), quantum dots (QDs) [ 24 , 25 ], nanoparticles (NPs) [ 26 , 27 ], fluoropolymers [ 28 ], dyes [ 29 , 30 ], and porphyrins [ 31 , 32 , 33 ] have been the most utilized. For the fabrication of sensors, these luminescent materials are usually entrapped or encapsulated in different matrices [ 34 , 35 ] or shells [ 36 , 37 ], which must be designed to facilitate the interaction between the analyte and the sensing material [ 38 ].…”

Luminescence-based sensing applications range from agriculture to biology, including medicine and environmental care, which indicates the importance of this technique as a detection tool. Luminescent optical sensors are required to be highly stable, sensitive, and selective, three crucial features that can be achieved by fabricating them by means of the layer-by-layer nano-assembly technique. This method permits us to tailor the sensors′ properties at the nanometer scale, avoiding luminophore aggregation and, hence, self-quenching, promoting the diffusion of the target analytes, and building a barrier against the undesired molecules. These characteristics give rise to the fabrication of custom-made sensors for each particular application.
