“…Aggregates of Rh6G suppress fluorescent emission, and therefore restrict its promising extensive photophysical applications. Over the years considerable efforts have been devoted to investigate and characterize the possible formation of fluorescent or non-fluorescent dye aggregates, including incorporating Rh6G into organic polymers [9,10], surfaces of glass [11,12], quartz [13,14], clays [15,16], silica gels [17] and mesostructured silica [18][19][20]. However, using a simple and effective method to control the aggregation states of Rh6G is still a very challenging task.…”

“…Very interesting results have been obtained in this field by Salleres et al [22,23] and Esposito et al [24] both research groups working on organophilic smectite and different dyes. The incorporation of rhodamine 6G (R6G) in laponite clay, previously modified with dodecyltrimethyammonium chloride, produces hybrids with improved photophysical properties with respect to those obtained by using the unmodified clay.…”

Thermoplastic polymers like polyolefins, polyesters, polyamide, and styrene polymers are the most representative commodity plastics thanks to their cost-efficient manufacturing processes, excellent thermomechanical properties and their good environmental compatibility, including easy recycling. In the last few decades much effort has been devoted worldwide to extend the applications of such materials by conferring on them new properties through mixing and blending with different additives. In this latter context, nanocomposites have recently offered new exciting possibilities. This review discusses the successful use of nanostructured dispersed substrates in designing new stimuli-responsive nanocomposites; in particular, it provides an updated description of the synthetic routes to prepare nanostructured systems having the typical properties of thermoplastic polymers (continuous matrix), but showing enhanced optical, conductive, and thermal features dependent on the dispersion topology. The controlled nanodispersion of functional labeled clays, noble metal nanoparticles and carbon nanotubes is here evidenced to play a key role in producing hybrid thermoplastic materials that have been used in the design of devices, such as NLO devices, chemiresistors, temperature and deformation sensors.

“…Spin-coated cationic clay films immersed in organic dye solutions (e.g xanthene dyes and thiazine dyes) can form functionalized dye/clay films. 78,[95][96][97][98] On one hand, the thickness of the clay film can be controlled by the viscosity of the clay suspension, the speed rate of the spin-coating procedure, and the number of spinnings. 97 For example, the thickness of laponite films increased from 250 (in the center) and 120 nm (at the edge) to 450 (in the center) and 250 nm (at the edge) after a double-covered spin-coating process.…”
