Chemical modification of carboxylated MWCNTs for enhanced electrical conducting and magnetic properties

Effective dispersion of oxidized multi-walled carbon nanotubes using a water-soluble N,O-carboxymethyl chitosan via non-covalent interaction

“…Nevertheless, this approach disrupts the sidewall structures of MWCNTs to alter their valuable properties. 10 In this regard, non-covalent functionalization is a promising way via the physical adsorption interaction between appropriate dispersing agents and MWCNTs. 11 …”

“…Nevertheless, this approach disrupts the sidewall structures of MWCNTs to alter their valuable properties. 10 In this regard, non-covalent functionalization is a promising way via the physical adsorption interaction between appropriate dispersing agents and MWCNTs. 11 Up to now, MWCNTs are dispersed by non-covalent dispersion with the assistance of surfactants, 12 aromatic compounds, 13 and polymers.…”

Simultaneous determination of hydroquinone and catechol by a reduced graphene oxide–polydopamine–carboxylated multi-walled carbon nanotube nanocomposite

“…In addition, multi-walled carbon nanotubes (MWCNTs) have wellknown excellent properties and play a momentous role in the eld of electrochemical research, and carboxylated MWCNTs (cMWCNTs) have more reaction diversity due to the carboxyl groups. [35][36][37] In this study, a PDA-RGO nanocomposite was fabricated through a convenient and mild method, which was combined with cMWCNTs to construct a novel nanocomposite. The proposed RGO-PDA-cMWCNT nanocomposite was characterized and applied as an electrode modier aiming at improving the detection of HQ and CT.…”

Preparation and properties of CNTs loaded bisphenol F epoxy nanocomposites modified by noncovalent dispersant and nonionic surfactant

“…A large number of studies have shown that CNTs are mainly dispersed in two ways: chemical functionalization and physical adsorption. Among them, chemical functionalization can disperse CNTs effectively for a long time, but there are some disadvantages, such as complex processes, destruction of CNTs wall structure and high cost 27,28 . As for physical adsorption, the introduction of functional groups or π‐π bonds on the surface of CNTs can to improve their surface activity.…”
