“…S1 in supplementary data.The FTIR spectra of PoPDA@MWCNTs nanocomposite showed almost identical characteristic peaks at 3360, 1660, 1497, and 1210 cm −1 , respectively, which were in accordance with the previous reports composites with un-functionalized MWCNTs23 . On the other hand, the FMWCNTs exhibit a characteristic peaks at 3356, 1680 and 1080 cm -1 can be attributed to the stretching vibrations of O-H, C=O of carboxylic acid and C-O, respectively 5 .…”

Recently, the corrosion of metals is an important academic and industrial concern which has received a significant attention. Poly (o-phenylenediamine) (PoPDA) based nanocomposites with unfunctionalized multi-walled carbon nanotubes (MWCNTs) and functionalized multiwalled carbon nanotubes (FMWCNTs) were prepared through emulsion polymerization using sodium dodecyl sulfate (SDS) as an emulsifier and ammonium persulfate (APS) as an oxidant. Fourier transform infrared (FT-IR) spectra were confirmed the construction of nanocomposites. The morphology of synthesized nanocomposites was characterized by scanning electron microscopy (SEM). X-ray diffraction (XRD) patterns of the nanocomposites indicated more crystalline nature than that of the bare PoPDA. Thermal stability of nanocomposites was improved relative to bare PoPDA. The corrosion protection performance of the coatings containing PoPDA@MWCNTs, PoPDA@FMWCNTs and PoPDA on steel was evaluated using potentiodynamic polarization, electrochemical impedance spectroscopic (EIS) and open circuit potential (OCP) measurements in 3.5 % NaCl solution. The obtained results of potentiodynamic polarization, EIS and OCP showed the PoPDA@MWCNTs nanocomposite coated steel had excellent corrosion inhibition behavior in saline solution.

“…7, the electrode has retained about 92% of its initial response current after 90 days of use. In addition, experiments (not listed in this paper) also prove that there is no loss of electroactivity after the continuously cyclical sweep for 30 cycles in 2.0 × 10 −4 mol L −1 AA, which is superior to most of the reported CNT/PANI electrodes [40][41][42], suggesting that the GSCNTs/PANI-CME has a relatively high stability.…”

“…The spectrum of PDMA (Figure 2A) exhibits the main characteristic bands in the 400 to 4000 cm −1 range [22,23]. A broad, weak band at ~3237 cm −1 is attributed to the N–H stretching mode and the peak at 1194 cm −1 corresponds to the quinoid rings in the polymer backbone, while the corresponding stretching vibration bands for the benzenoid rings occur at 1504 and 1447 cm −1 .…”

An impedimetric immunosensor for fumonisin B1 (FB1) was developed from a poly(2,5-dimethoxyaniline)-multi-walled carbon nanotube (PDMA-MWCNT) composite on the surface of glassy carbon electrode (GCE). The composite was prepared electrochemically and characterized using cyclic voltammetry. The preparation of the FB1 immunosensor involved the drop-coating of a bovine serum albumin mixture of the anti-fumonisin antibody (anti-Fms) onto the composite polymer-modified GCE. The electrochemical impedance spectroscopy (EIS) responses of the FB1 immunosensor (GCE/PDMA-MWCNT/anti-Fms) have a linear range of 7 to 49 ng·L−1, and the corresponding sensitivity and detection limits are 0.272 kΩ L·ng−1 and 3.8 pg·L−1, respectively. The limit of detection of the immunosensor for certified corn sample (i.e., certified reference material) is 0.014 ppm FB1, which is in excellent agreement with the value published by the vendors and significantly more accurate than that obtained with enzyme-linked immunosorbent assay (ELISA).
