“…As shown in the FT-IR results (in Na + -MMT spectrum), the peaks appearing at 476 and 1037 cm −1 are related to the bending and stretching Si-O vibrations [ 2 , 18 ]. Additionally, the peaks at around 532, 913, 1638–3435, and 3623–3694 cm −1 are corresponding to the Si-O-Al vibration and MgO groups, Al 2 OH bending groups, scissoring and symmetric vibrations of OH units, and stretching of OH (SiOH groups), respectively [ 2 , 18 , 51 ]. In the CT spectrum, the peaks appearing at 615–866 cm −1 are related to the primary and secondary amines [ 51 ].…”

“…The XRD pattern of the samples shows that they have peaks with a center at 2θ = 7.4° (d-spacing = 11.88 Å) and 2θ = 5.63° (d-spacing = 16.78 Å), respectively. It is observed that there is an increase in d-spacing in CT-MMT, which is due to the absence of Na + cation and the presence of CT [ 2 , 18 ]. Figure 2 c shows the TGA curves of Na + -MMT and CT-MMT.…”

“…It seems that some of the plates are partly separated and the CT-MMT has greater disunion than the Na + -MMT. Although it has been reported in the literature that the morphology does not change significantly after modification [ 18 , 56 ]. Additionally, the TEM images ( Figure 3 b) show the presence of CT particles in MMT (indicated by the red arrow).…”

“…Polymers are always one of the most amazing materials that are used in many fields. Polymer coatings are one of the ways to protect metals, in fact, they can be applied on different substrates [ 18 , 19 , 20 , 21 , 22 ]. The properties of polymer coatings, such as hydrophobicity, anti-fouling, self-healing, resistance to chemicals, and thermal, as well as their antimicrobial capabilities, have made them very popular [ 22 , 23 , 24 ].…”

In this study, Clitoria ternatea (CT) was incorporated into the structure of sodium montmorillonite (Na+-MMT), then these new nanoparticles (CT-MMT) were added to sol-gel-based hybrid silanol coatings (SGC). The results of the CT-MMT investigation using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscope (TEM) confirmed the presence of CT in the structure. The results of polarization and electrochemical impedance spectroscopy (EIS) tests showed that the presence of CT-MMT in the matrix improves corrosion resistance. The EIS results showed that the coating resistance (Rf) of the sample containing 3 wt.% CT-MMT after immersion was 687 Ω·cm2, while this value was 218 Ω·cm2 for pure coating. CT and MMT compounds improve corrosion resistance by blocking anodic and cathodic regions, respectively. Additionally, the presence of CT in the structure created antimicrobial properties. CT contains phenolic compounds that have the ability to suppress by membrane perturbation, reduction of host ligands adhesion, and neutralizing bacterial toxins. Therefore, CT-MMT showed inhibitory effects and killing of Staphylococcus aureus (gram-positive bacteria) and Salmonella paratyphi-A serotype (gram-negative bacteria), and also improved corrosion resistance.

“…The peak attributed to symmetrical and asymmetrical elongation vibrations of the Si-O-Si occurs at 1026 cm −1 [35]. In addition, the peak obtained at around 919 cm−1 suggests Al-OH deformation vibration [36]. Also, the peaks at around 875, 774, 690, 517, and 466 cm -1 are attributed to the deformation of OH linked to Al 3+ and Fe 3+ , the vibration of groups MgO and Si-O-Al, Si-O-Si bending vibrations, stretching vibrations and elongation of Si-O-Al, [37][38][39].…”

This study aimed to investigate the effects of phosphogypsum addition on ceramic membrane properties. In this regard, clay and phosphogypsum were characterized using FTIR and laser particle sizer. The ceramic paste was prepared by incorporating varying amounts of phosphogypsum (10 to 50%), followed by molding using a semidry-pressing process at 10 bars pressure and sintering temperature at 900℃. The raw materials and prepared membranes were analyzed using FTIR, laser particle size, contact angle, porosity, and mechanical strength to evaluate the properties of the resulting ceramic membranes. The study showed that as the amount of phosphogypsum increased from 10% to 50%, the membrane's hydrophilicity significantly increased, while its mechanical strength decreased by 35% and porosity increased by 26%. Moreover, the permeability of distilled water also showed a significant increase of 67% when the amount of phosphogypsum was increased from 10% to 50%.These observations suggest that phosphogypsum can significantly influence ceramic membrane properties, which may have implications for its use in various membrane applications. The findings of this research contribute to our understanding of the potential use of phosphogypsum as a valuable material for ceramic membrane production, with important implications for sustainable waste management practices. Future studies can focus on exploring the suitability of these ceramics for various applications and their environmental impact.
