“…This behavior frequently has been reported to be the result of functionalization, especially when it is accompanied by peak shifting to less than 2θ degrees [69][70][71]. Figure 10 shows the XRD diffraction peaks in the different functionalized groups compared to p-Gr and o-Gr.…”

In this work, DESs were used as functionalizing agents for graphene due to their potential to introduce new functional groups and cause other surface modifications. Eighteen different types of ammonium-and phosphonium-salt-based DESs were prepared and characterized by FTIR. The graphene was characterized by FTIR, STA, Raman spectroscopy, XRD, SEM, and TEM.Additional experiments were performed to study the dispersion behavior of the functionalized graphene in different solvents. The DESs exhibited both reduction and functionalization effects on DES-treated graphene. Dispersion stability was investigated and then characterized by UV-vis spectroscopy and zeta potential. DES-modified graphene can be used in many applications, such as drug delivery, wastewater treatment, catalysts, composite materials, nanofluids, and biosensors. To the best of our knowledge, this is the first investigation on the use of DESs for graphene functionalization.

“…Recently, the goal of researches has been shifted from the synthesis, purification, and characterization of nanotubes to their new functionalization; therefore, the modification of CNTs has become an important subject these days [7][8][9][10]. Different groups or compounds can be attached to the sidewall of the CNTs by different mechanisms such as covalent functionalization to the nanotube ends or defects, sidewall covalent functionalization, and noncovalent exohedral functionalization; for example, wrapping nanotubes by polymers [11].…”

“…To overcome the issues related to the poor dispersion of CNTs in polymers, different approaches have been pursued . Among others, the surface functionalization of CNTs with several functional groups is able to enhance the compatibility with the matrix . Particularly, the modification of CNTs surface can be obtained through different methods, such as defect , covalent , and non‐covalent functionalization.…”

Silanol polyhedrad oligomeric silsesquiosane terminated with phenyl rings (phPOSS) has been considered as dispersing agent for carbon nanotubes (CNTs) in polyamide (PA) matrix. Two different approaches have been followed for the introduction of the phPOSS molecules: a “classical” approach which involves the introduction of the dispersing agent during the melt mixing, and an “innovative” approach, consisting in the immobilization, either covalent and non‐covalent, of phPOSS molecules onto CNTs surface. The properties of PA‐based nanocomposites, containing free phPOSS molecules and phPOSS molecules immobilized onto the CNTs outer surface, have been evaluated through rheological, mechanical, thermo‐mechanical, and morphological analyses. Obtained results highlight the effectiveness of the immobilization of the dispersing molecules onto the surface of the CNTs because of the enhancement of the interfacial interaction between the nanofillers and matrix. The preferential localization of the phPOSS molecules at the interface between the nanofillers and polymer chains helps the CNTs dispersion during melt processing and promote the stress transfer across the interface, leading to the obtainment of nanocomposites with enhanced mechanical performance.
