“…Using this concept, a CNT‐incorporated polymer‐based monolithic capillary column was recently introduced by Zhang et al . using a mixture of RTILs and DES that facilitated the uniform dispersion of SWCNTs in the pre‐polymerization solution . BMA, EDMA and a mixture of RTILs and DES were used as the monomer, crosslinker and the porogens, respectively, in preparing the monolithic column.…”

This review article is concerned with the recent advances made in the field of organic polymer-based monoliths with incorporated nanostructured materials (NSMs) for use in liquid chromatography and capillary electrochromatography. It covers the pertinent literature published over the last 7-8 years with a total of 56 references. The present article has two distinct parts: one major part encompassing "traditional" organic polymer-based monoliths modified with NSMs and a minor part on cryogels modified with NSMs.

“…CNTs dispersion was improved by pre‐entangling CNTs with oligomers , carboxylation , and partial oxidation . Besides, homogeneous dispersion of CNTs in ternary alcohol solutions and binary ionic liquids was also reported. Wang and Yan first fabricated graphene oxide (GO) nanosheets incorporated monolithic column by one‐step room temperature polymerization .…”

“…Modification of stationary phases in packed or monolithic columns by carbon‐based nanomaterials was typically performed in the following two means: Physically entrapping, incorporation, or adsorption in the substrate; chemically coating or grafting on the surface. In the preparation of multi‐walled and single‐walled CNTs incorporated monolithic columns , much attention was paid to homogeneous dispersion of CNTs. CNTs dispersion was improved by pre‐entangling CNTs with oligomers , carboxylation , and partial oxidation .…”

Single-walled carbon nanohorns have received great interest for their unique properties and diverse potential applications. Herein, we demonstrated the feasibility of single-walled carbon nanohorns incorporated poly(styrene-divinylbenzene) monolith as the stationary phase for capillary electrochromatography, which were prepared by one-step in situ copolymerization. Single-walled carbon nanohorns were dispersed in styrene to give a stable and homogeneous suspension. The monolithic column gave effective separation for a wide range of aromatic compounds, which was based on hydrophobicity and π-π electrostatic stacking of single-walled carbon nanohorns. The precisions of migration time and peak area varied in the ranges of 1.4-1.9% for intraday trials and 1.7-3.5% for interday trials, and 3.2-6.7% for intraday trials and 4.1-7.4% for interday trials, and 3.6-7.2% for inter-column trials and 5.2-21.3% for inter-column trials, respectively, indicating the good reproducibility of single-walled carbon nanohorns embedded monolithic columns.

“…This is due to their tendency of introducing atomic defects and internal stresses into the nanotube [89]. An alternative dispersion solvent, proposed by Zhang, Gao, Huang and Liu [89], involved a green synthesis technique using mixtures of ionic liquids and deep eutectic solvents for homogeneous dispersion of carbon nanotubes. The green approach was able to achieve an enhanced separation performance for alkyl phenones and benzenes.…”

Monoliths are continuous adsorbents that can easily be synthesised to possess tuneable meso-/macropores, convective fluid transport, and a plethora of chemistries for ligand immobilisation. They are grouped into three main classes: organic, inorganic, and hybrid, based on their chemical composition. These classes may also be differentiated by their unique morphological and physicochemical properties which are significantly relevant to their specific separation applications. The potential applications of monoliths for molecular separation have created the need to enhance their characteristic properties including mechanical strength, electrical conductivity, and chemical and thermal stability. An effective approach towards monolith enhancement has been the doping and/or hybridization with miniaturized molecular species of desirable functionalities and characteristics. Nanoparticles are usually preferred as dopants due to their high solid phase dispersion features which are associated with improved intermolecular adsorptive interactions. Examples of such nanomaterials include, but are not limited to, carbon-based, silica-based, gold-based, and alumina nanoparticles. The incorporation of these nanoparticles into monoliths via in situ polymerisation and/or post-modification enhances surface adsorption for activation and ligand immobilisation. Herein, insights into the performance enhancement of monoliths as chromatographic supports by nanoparticles doping are presented. In addition, the potential and characteristics of less common nanoparticle materials such as hydroxyapatite, ceria, hafnia, and germania are discussed. The advantages and challenges of nanoparticle doping of monoliths are also discussed.
