“…The prominent bands found in the C20A spectrum (Figure 4) and Table 4 are at 3632, 2921–2849 and 1475 cm −1 (proving the organo‐modification of the MMT), 1639, 1004, 917, and 725 cm −1 69 . These bands are associated with the aluminosilicate chemical composition of the C20A nanoclay 69 .…”

“…The influence of C20A nanoclay on the membranes can be verified in the increased intensity for the bands described in Table 4, referring to the stretching of alkylammonium and binding of organic groups in the clay, SiO plane vibration e AlOHAl stretching of aluminates (Figure 11b), and the band regarding the stretching of alkylammonium and binding of organic groups in the clay (Figure 11c). 69 The EIPS/NIPS nanocomposite membranes had similar spectra to pure polymer but with higher transmittance intensity. The spectra resemble those reported by Oliveira and co‐workers, who obtained PBAT membranes with 6 wt.% porogen relative to the weight of PBAT in solution (15% w w −1 PBAT, 85% w w −1 chloroform), with bands at identical wavelengths (806, 1316, 1733, and 2897 cm −1 ) 42 .…”

The method employed for membrane preparation and nanoparticle incorporation in membrane systems can affect their properties. This work aims to compare the better strategy to obtain membranes from the preparation of PBAT [Poly(butylene adipate co‐terephthalate)] containing nanoclay Cloisite® 20A (C20A) (0, 0.5, and 1 wt.%) by combined Evaporation/Non‐solvent Induced Phase Separation (EIPS/NIPS) or dip coating methods. The SEM, TGA, contact angle measurements, FTIR, XRD, mechanical testing, and cost analysis characterized EIPS/NIPS to dip coating membranes. EIPS/NIPS membranes had smaller pores (0.3–0.5 μm), with a more homogeneous pore diameter distribution due to C20A nanoclay insertion. PBAT/0.5% C20AEIPS/NIPS was the more hydrophilic membrane (37°) with better mechanical properties proven by statistical analysis. The cost analysis showed that EIPS/NIPS membranes production cost per square meter (m2) was lower (US$ 73.4–73.8) than dip coating (US$ 89.0–99.2). The EIPS/NIPS method was the most economically and statistically advantageous, and its properties can favor future applications for PTEs removal in aqueous media.

“…The onset of the third degradation stage occurs at approximately 500 °C and splits into two peaks: one at 540 °C and the second at 620 °C. This can be attributed to the dehydroxylation of the aluminosilicate lattice that leads to the release of structurally bound water [ 37 , 38 , 39 ]. Carbonaceous char is formed at temperatures above 700 °C.…”

Polyimide matrix nanocomposites have gained more attention in recent years due to their high thermal stability, good interfacial bonding, light weight, and good wear resistance and corrosion, factors that make them find great applications in the field of aerospace and advanced equipment. Many advancements have been made in improving the thermal, mechanical, and wear properties of polyimide nanocomposites. The use of nanofillers such as carbon nanotubes, graphene, graphene oxide, clay, and alumina has been studied. Some challenges with nanofillers are dispersion in the polymer matrix and interfacial adhesion; this has led to surface modification of the fillers. In this study, the interaction between clay and graphene to enhance the thermal and thermal-oxidative stability of a nanocomposite was studied. A polyimide/graphene nanocomposite containing ~12.48 vol.% graphene was used as the base nanocomposite, into which varying amounts of clay were added (0.45–9 vol.% clay). Thermogravimetric studies of the nitrogen and air atmospheres showed an improvement in thermal decomposition temperature by up to 50 °C. The presence of both fillers leads to increased restriction in the mobility of polymer chains, and thus assists in char formation. It was observed that the presence of clay led to higher decomposition temperatures of the char formed in air atmosphere (up to 80 °C higher). This led to the conclusion that clay interacts with graphene in a synergistic manner, hence improving the overall stability of the polyimide/graphene/clay nanocomposites.
