Fabrication of cross-linked multi-walled carbon nanotube coatings with improved adhesion and intrinsic strength by a two-step synthesis: electrochemical deposition and hyperthermal proton bombardment
نویسندگان
چکیده
A two-step synthesis for multi-walled carbon nanotube (MWCNT) coating was reported that includes an electrochemical deposition followed by 10 eV hyperthermal proton bombardment at a dose as low as 1×1016 H+/cm2. Electrochemical deposition ensures an improved adhesion of MWCNT coating on metal substrates, while hyperthermal proton bombardment effectively induces inter-chain cross-linkages among MWCNTs, leading to a coating with both higher stiffness and mechanical strength. It was found experimentally that the MWCNT film made by the proposed two-step synthesis can better resist spinning and ultrasonic rinsing in both organic (hexane) and aqueous (water) media.

The electrochemical oxidation of sulfamethazine (SMZ) has been studied at a multi-walled carbon nanotubes modified glassy carbon electrode (MWCNT-GCE) by cyclic voltammetry. This modified electrode (MWCNT-GCE) exhibited excellent electrocatalytic behavior toward the oxidation of SMZ as evidenced by the enhancement of the oxidation peak current and the shift in the anodic potential to less posit...

We studied solvent-free, one-step functionalization of aligned multi-walled carbon nanotube (MWNTs) using initiated chemical vapor deposition. Aligned MWNTs with a variety of aspect ratios were uniformly functionalized with an epoxy polymer. The vapor deposition process allowed excellent retention of the nanotube alignment and control of the porosity of the resultant MWNT nanostructure. In addi...
