Carbon Nanotubes (CNTs) chemistry is under constant evolution, as a consequence of the deep interest\ud of the scientific community in finding new applications for these versatile materials. New and old synthetic protocols\ud are used for improving the control of the functionalization degree of the final materials and for offering to scientists\ud the possibility to fine-tune their final properties. In this Review, we focus the attention on radical reactions,\ud a class of protocols characterized by small number of steps, different degrees of functionalization and enhanced\ud solubility of the final modified CNTs, in the desired environment. The most well-known protocols are analysed\ud providing some relevant examples appeared in the literature in the last years, monitoring the new application fields\ud and giving insights into their mechanism in order to explain why these protocols are considered standard procedures for a wide number of\ud scientific groups

“…The introduction of dihalocarbene onto the sidewalls of carbon materials has been extensively studied [39][40][41]. The conventional method of producing reaction intermediates by chloroform (CHCl 3 ) and sodium hydroxide (NaOH) under reflux conditions was feasible, and the functionalization of graphene by the dichlorocarbene with the assistance of phase transfer catalyst (PTC) was carried out (Fig.…”

Owning to its large surface area and atomic thickness, graphene possesses exceptional mechanical, optical and electrical properties. Up to now, graphene and its composites/ hybrids have been widely used in various scientific fields such as drug carriers, electronics, transistors, sensors, conductive materials and so on. Unfortunately, the prospects of more extensive applications of graphene have been impeded by its poor dispersibility, processability and tunability. However, graphene can be chemically modified, and the well-chosen organic molecules with active functional groups would react with graphene to form low-dimensional graphene-organic architectures. The controlled functionalization of organic molecules onto the defective sites of graphene is a very effective route for fabrication of graphenebased composite materials. The aim of this article is to present an overview of the surface functionalization methodologies which are valuable for the selective construction of highly functionalized graphene with controllable properties. The interactions between graphene and organic molecules were discussed in detail. We hope to provide some useful references and enlightened views for scientific research groups.

“…Chitosan (CS) grafted MWNTs (S.MWNT-CS) were prepared by treating the ox-MWNTs with CS through a microwave-assisted reaction [39,40]. The dihalocarbene functionalized MWNTs (S.MWNTs-2040-CCl 2 , S.MWNTs-2040-CBr 2 , and S.MWNTs-2040-CI 2 ) were prepared by reaction of raw S.MWNTs-2040 with sodium hydroxide (NaOH) with chloroform, or bromoform, or iodoform, respectively [41][42][43]. And poly(ethylene glycol) ( = 400; PEG400) grafted MWNTs (S.MWNT-PEG400) were obtained by firstly acyl chlorination of ox-MWNTs with thionyl chloride (SOCl 2 ), followed by an esterification reaction with PEG400 [44][45][46].…”

In an attempt to explore the possibility of using carbon nanotubes (CNTs) as efficient adsorbents for removal of pollutants from the contaminated water, the adsorption ofp-nitrophenol (PNP) on raw multiwalled carbon nanotubes (r.MWNTs) with different outer diameters, various functionalized multiwalled carbon nanotubes (f-MWNTs), raw single-walled carbon nanotubes (r.SWNTs) and oxidized single-walled carbon nanotubes (ox-SWNTs) has been investigated. The ox-SWNTs showed better adsorption ability for PNP with different concentrations, while lower uptake capacity was found for all of the r.MWNTs andf-MWNTs. The removal efficiency of PNP by ox-SWNTs was around 98%, indicating that ox-SWNTs possess a great potential application prospect for removing PNP from aqueous solutions.
