Applications of Synthesis Methods for Preparation of Carbon Nanotubes and Related Nanomaterials

Dear Colleagues,

Single-walled carbon nanotubes (SWCNTs) have unique electronic, electrical, optical, chemical and mechanical properties. Atomic structure of SWCNTs can be represented as hollow cylinder rolled from a graphene sheet. The electronic properties of SWCNTs are dependent on their atomic structure. The SWCNTs can have metallic or semiconducting conductivity type depending on their chirality. The SWCNTs are synthesized by arc-discharge, laser ablation and chemical vapor deposition methods. Due to the nonhomogeneity of the properties of synthesized carbon nanomaterials, methods for tailoring their electronic properties were developed. These methods include (i) the covalent modification of the outer surface, (ii) noncovalent modification of the outer surface, (iii) the intercalation, and filling of carbon nanomaterials. The chemical functionalization of carbon nanomaterials was established as a method of controllable modification of their electronic properties. It was demonstrated that the channels of SWCNTs can be filled with electron acceptor and donor substances with appropriate chemical and physical properties. For the chemical functionalization of carbon nanomaterials, the gas phase, solution and melt methods were applied. The gas phase method is based on the modification of carbon nanomaterials with gaseous substances. During the synthesis, the vapor of the substance condenses and diffuses inside carbon nanomaterial. The cooling of the system leads to crystallization of the substance. The solution method is based on the chemical modification of carbon nanomaterials with the substance dissolved in a solvent. The synthesis procedure involves the multi-step filtration and cleaning stages. The melt method is based on the chemical modification of carbon nanomaterials with melted substances. During the synthesis process, the melts encapsulate inside carbon nanomaterials, and then the melt is crystallized upon cooling.

This Special Issue will focus on application of synthesis methods for preparation of carbon nanotubes and related nanomaterials. The pristine, chemically functionalized carbon nanomaterials, including carbon nanotubes, graphene, graphene nanoribbons, 2D heterostructures, fullerenes, nanodiamonds, and other novel nanostructures, are considered. The issue is intended to provide a comprehensive overview of the recent and forthcoming progress in the field. It will help researchers to quickly find and identify related and relevant publications for their own work on carbon nanomaterials.

We invite interested authors to submit their original experimental and theoretical papers as well as review articles themed within the subject for inclusion in this Special Issue, which will boost the visibility of their work.
