Towards the development of flexible carbon nanotube–parafilm nanocomposites and their application as bioelectrodes

Abstract

Soft, flexible and conductive interfaces, which can be used as electrode materials integrated with commercial electronic components and the human body for continuous monitoring of different analytes are in high demand in wearable electronics.

Quantification of Chlorpyrifos Residues in Water under Thermodynamically Favorable Electrodics Using the f-MWCNT/N-(2-C2H5O) ED(CH3COONa)3 Composite of Superior Selectivity

“…After acid functionalization of MWCNT, strong −OH, −C�C/−CO, and −C−N vibrations were observed at 3438, 1635, and 1050 cm −1 , respectively (Figure 1B(b)). 24,25 In 28,29 From the above-mentioned observations, it has been confirmed that the effective formations of f-MWCNT, f-MWCNT/N-(2-C 2 H 5 O) ED(CH 3 COONa) 3 , and f-MWCNT/DETA (CH 3 COOH) 5 have occurred.…”

“…Also, a weak hydroxyl peak was observed at 3417 cm –1 that might be caused by moisture absorption. After acid functionalization of MWCNT, strong −OH, −CC/–CO, and −C–N vibrations were observed at 3438, 1635, and 1050 cm –1 , respectively (Figure B­(b)). , …”

“…The formation of f-MWCNT by acid treatment directly affects the sp 3 and sp 2 bonds present in the hydrocarbon network. Besides, the changes in the carbon ratio provide potential information about the effect of functionalization. , Raman spectra showed D, G, and 2D peaks for MWCNT at 1355, 1576, and 2702 cm –1 , respectively, where the predominance of sp 2 was observed as a result of the well-organized hydrocarbon chains (Figure A). At the same time, the functionalized MWCNT showed increased sp 3 carbon due to the tagging of functional groups.…”

Development of polyvinylpyrrolidone, inorganic nanoparticles, and lithium carbonate nanostructured systems

“…The R a value was 8.33, the R q value was 20.20, and the difference between R a and R q was 11.87. The difference between Ra and Rq was 11 times higher than that of the PVP/MMT nanocomposites, and the roughness value (RMS) was 300 nm, which indicates the deposition of the drug and nanoclay at the polymer surface 45 . The nanoclay and drug tend to migrate to the surface of the PVP, resulting in greater roughness in certain areas 28 …”
