“…A slight improvement of Δ E p for the WE spray‐coated with plasma‐oxidized MWCNTs (SC‐NC7‐m1) compared to SC‐NC7‐m0 prepared from as‐received MWCNTs (Table , Fig. e and f) revealed the importance of the pretreatment of MWCNTs that leads to improvement of their dispersion in a suspension and/or grafting of oxygen functional groups . The present experiments did not show improvement of the WE by using MWCNTs as compared to the plasma oxidation of the WE made by screen printing of DuPont 7102 paste.…”

“…A comparison of SC‐NC7‐m X spray‐coated electrodes showed that the electrode modified with the plasma‐oxidized MWCNTS exhibited the best electrochemical behaviour for both tested model analytes. It can be caused by improved dispersion of MWCNTs in DMF and/or grafted oxygen functional groups .…”

“…The plasma gases are selected in order to represent treatments that can introduce oxygen (Ar/O 2 plasma) or amine (Ar/cyclopropylamine or Ar/NH 3 plasma) functional groups. The choice is based on previously gained experience with CNTs functionalization and deposition of amine‐rich polymers . The electrochemical characterization of prepared electrodes is performed using potassium ferro/ferricyanide and dopamine like model analytes.…”

The screen-printed working electrode (WE) of an electrochemical sensor was modified with multi-walled carbon nanotubes (MWCNTs) and a plasma treatment. The plasma treatment was performed using radio frequency capacitively coupled discharge in Ar/O 2 , Ar/cyclopropylamine and Ar/NH 3 . The surface of the WEs was characterized by scanning electron microscopy and their electrochemical behaviours were studied using potassium ferro/ferricyanide and dopamine as standard electrochemical probes. The most promising results were obtained with the electrodes modified by oxygen plasma because the reversibility and the current response were both improved significantly. The peak-to-peak separation improved from 879 to 116 mV after the oxygen plasma treatment of the bare DuPont 7102 electrode. Spray-coated MWCNTs had a positive effect on the performance of the screen-printed DuPont 7102 WE if the sprayed MWCNTs layer was thicker. However, this improvement did not reach the performance of the screenprinted DuPont electrode modified by plasma oxidation. The modification by Ar/NH 3 had weak influence on the response depending on the type of the electrode and plasma treatment in Ar/cyclopropylamine plasma led to an inhibition of the electrochemical reactivity due to a preparation of too thick insulating film.MWCNTs modified screen-printed disposable electrochemical microsensor for trace detection of various substances in a droplet.

“…The broad peak at 1 612 cm −1 can be due to the vibrations of carbonyl groups or to skeletal CC aromatic vibrations of MWCNTs . The peak at 1 718 cm −1 suggests the presence of stretching CO vibrations arising from carboxylic acids . The peaks at ≈1 660 cm −1 is usually attributed to the carbonyl groups and CC .…”

Poly(acrylic acid)‐multiwall carbon nanotubes (PAA‐MWCNTs) was synthesized and was used as a adsorbent for the preconcentration and removal of trace Hg(II) from aqueous solution. Microwave plasma technique was used to activate MWCNT surfaces, which induces the polymerization of acrylic acid on MWCNTs. Fourier transform infrared spectroscopy, Raman spectroscopy, X‐ray photoelectron spectroscopy, and thermogravimetric analysis demonstrated that acrylic acid monomer was polymerized on MWCNT surfaces. Due to the effect of oxygen containing functional groups of Poly(acrylic acid), the adsorption capacity of PAA‐MWCNTs is much higher than that of MWCNTs. Therefore, PAA‐MWCNTs is a promising adsorbent in the preconcentration and removal of heavy metal ions from large volumes of aqueous solutions.
