Highly conductive paper fabricated with multiwalled carbon nanotubes and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) by unidirectional drying

Highly sensitive, room temperature gas sensor based on polyaniline-multiwalled carbon nanotubes (PANI/MWCNTs) nanocomposite for trace-level ammonia detection

“…Among the various conducting polymers, polyaniline (PANI) has been identified as an interesting candidate in sensor applications owing to its unique electrical properties, easy fabrication process and unique redox properties [20,[22][23]. Recent studies on MWCNT/Polymer composites have revealed that the combination of MWCNT and polymer in the composite material could broaden the application range of the individual materials [24][25][26][27][28][29].…”

The effect of substrate pore size on the network interconnectivity and electrical properties of dropcasted multiwalled carbon nanotube thin films

“…Using the same procedure described by Huang et al, 10 1 mg/mL MWNTs were added to 15 mL of distilled water with 10 mg/mL SDBS. In short, the MWNT dispersion was ultrasonicated for 10 min.…”

“…After the first 10 min, the SDBS surfactant was added in small quantities over another 10 min period of time, while the dispersion continued being ultrasonicated. Following the addition of the whole of the surfactant, the dispersion was magnetically mixed for 12 h. 10 All MWNT films reported in this paper were made using the same dispersion concentration.…”

“…17 The next drying method involved placing the MWNT dispersion onto the filter paper and holding it in a 65°C heater for 10 min (65°C dry). Finally, the last drying method is an adapted version of the one described by Huang et al 10 (called enhanced dry in this paper). In this method, a ceramic heating board was heated to 90°C and the filter paper was placed on top of it.…”

“…However, to have a sheet resistance of that level, the authors reported that the thickness of the films they made was near 10 lm. 11 In contrast, much thinner layers were necessary to achieve similar properties when MWNT films were made using a unidirectional drying method by Huang et al 10 . It has also been shown how an increase in the surface roughness of MWNTs on paper decreases the threshold field in field effect transistor technologies.…”
