The present review highlights the effect of different types of nanoparticles/nanotubes/nanolayers in polyamide nanocomposite properties. Polyamides belong to an important class of engineering polymers due to their interesting properties, such as temperature stability, good chemical resistance, relatively high tensile strength and stiffness. The availability of different types of nanoparticles and its functionalization, besides the improved knowledge on the integration with the polyamide matrix, has opened possibilities for developing new fields of applications and products.

“…Polymer/MMT nanocomposites can achieve more excellent thermal stability, mechanical, wettability and barrier properties relative to pure polymers on account of strong interfacial interactions generated between the dispersed MMT platelets and the polymer matrices [27][28][29][30]. The dispersion quality of MMT platelets in the polymer matrix is an important factor impacting the formation of effective interfacial interaction between them [31][32][33][34]. Good dispersion and exfoliation of MMT in polymer matrix is the prerequisite for significant improvement of nanocomposite properties [35][36][37].…”

In this research, a novel amphiphilic hydrophobically associative polymer nanocomposite (ADOS/OMMT) was prepared using acrylamide (AM), sodium 4-vinylbenzenesulfonate (SSS), N, N′-dimethyl octadeyl allyl ammonium bromide (DOAAB) and organo-modified montmorillonite (OMMT) through in situ polymerization. Both X-ray diffraction patterns and transmission electron microscopy images verified the dispersion morphology of OMMT in the copolymer matrix. Then, the effect of the introduction of OMMT layers on the copolymer properties was studied by comparing with pure copolymer AM/SSS/DOAAB (ADOS). The thermal degradation results demonstrated that the thermal stability of the ADOS/OMMT were better than pure copolymer ADOS. During the solution properties tests, ADOS/OMMT nanocomposite was superior to ADOS in viscosifying ability, temperature resistance, salt tolerance, shear resistance and viscoelasticity, which was because OMMT contributed to enhance the hydrophobic association structure formed between polymer molecules. Additionally, the ADOS/OMMT nanocomposite exhibited more excellent interfacial activity and crude oil emulsifiability in comparison to pure copolymer ADOS. These performances indicated ADOS/OMMT nanocomposite had good application prospects in tertiary recovery.

“…MMT was introduced into polymeric matrixes to produce polymer-clay nanocomposites (PCN) in which silicate layers of nanoclay were dispersed at the molecular level randomly and homogeneously. Many investigations on polymer nanocomposites [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] have been carried out due to their abilities, including enhancing mechanical and barrier properties rather than polymer composites containing traditional fillers. But the production of PCN with an acceptable level of clay layers dispersion within the polymer matrix is not accessible via physical mixing of polymer and clay particles [2].…”

The effect of 2‐benzylbenzimidazole (2‐BBI) was evaluated as surface modifier on the performance of Na+‐Montmorillonite nanoparticles (Na+‐MMT) in epoxy‐based coatings. Four epoxy‐based samples were prepared including 0, 1, 2, and 3 wt% of 2‐BBI‐(Na+‐MMT). The intercalation behaviors of epoxy resin in presence of 2‐BBI‐(Na+‐MMT) were determined by X‐ray diffraction (XRD), and field emission scanning electron microscope (FE‐SEM) analysis was carried out to depict the dispersion of 2‐BBI‐(Na+‐MMT). The pertaining reaction bonds of the 2‐BBI and (Na+‐MMT) were represented via Fourier transform infrared spectroscopy (FTIR), and pull‐off test was used for measuring the adhesion strength of the coated samples. Corrosion resistance and thermal properties of the coated samples were measured by electrochemical impedance spectroscopy (EIS) and differential scanning calorimetry (DSC), respectively. On the basis of the EIS results, the coated samples with 3 wt% 2‐BBI‐(Na+‐MMT)/epoxy had the highest corrosion resistance after 120 days immersion in 3.5 wt% NaCl solution. Also, based on the Brusher–Kingsbury equation, the amount of water absorption was calculated, in which 3 wt% 2‐BBI‐(Na+‐MMT)/epoxy had only 1.92% water absorption while 3 wt% (Na+‐MMT)/epoxy had 82 wt%. The results showed that 2‐BBI can improve the dispersion of the Na+‐MMT in the epoxy matrix by entering into their galleries and providing better compatibility between the inorganic clay nanoparticles and polymeric matrix. This issue led to the enhancement of the thermal and barrier properties of 2‐BBI‐modified (Na+‐MMT)/epoxy nanocomposites rather than unmodified ones. POLYM.
