Multi-wall carbon nanotubes bonding on silica-hydride surfaces for open-tubular capillary electrochromatography

Multi‐walled carbon nanotube composites with polyacrylate prepared for open‐tubular capillary electrochromatography

“…Silanization was a useful alternative for particles that could degrade at high-reaction temperatures [18,19,24]. In our previous paper, the CNT materials were designed to attach to the silica hydride modified phase by forming a stable covalent Si-C bond [25]. Until now, there have been no reports on the attachment of CNT onto capillaries through in situ polymerization, except for the simple synthesis of CNT/polyacrylate composites [26,27].…”

“…Some Jian-Lian Chen Te-Ling Lu Yi-Chen Lin nanomaterials, including latex [11], lipoprotein [12,13], silica [14,15], titanium oxide [16,17], gold [18][19][20], and carbon nanotubes (CNT) [21][22][23][24][25], have been used in OT-CEC. However, only a few examples involved in chemical bonding of these materials onto OT capillaries exist.…”

Open‐tubular capillary electrochromatography of small polar molecules using etched, chemically modified capillaries

“…Changes in the selectivity of the capillary are determined by attaching various organic moieties to the etched hydride surface via a hydrosilation reaction. Polymers [5] and carbon nanotubes [19] have also been utilized on silica hydride surface capillaries.…”

Development and Evaluation of a New Fluorinated Double-Wall Carbon Nanotube HPLC Stationary Phase

“…make them of particular interest in separation science [13,15]. For example, carbon nanotubes (CNTs) [16][17][18][19] were used in GC [20][21][22][23][24][25][26], HPLC [27][28][29][30][31][32][33][34][35], CE [36][37][38][39] and in capillary electrochromatography [40][41][42]. The interest of carbon nanotubes was that they could improve the analytical performances of the chromatographic methods such as higher resolution and chromatographic retention or better repeatability and stability due to the specific interactions between the analyte and the carbon nanotube (electrostatic Abstract A novel column based on silica-containing immobilized fluorinated double-wall carbon nanotubes (F-DWCNTs) was developed.…”
