Carbon Nanotube Doped Polyaniline

Abstract

Polyaniline/multiwalled carbon nanotube composite films have been fabricated. It is shown that the nanotubes affect the free N–H environment and quinoid units along the polymer backbone. A 10‐fold increase in conductivity is observed and elemental analysis indicates that the nanotubes compete with chloride ion during HCl doping (see Figure).

Increased response/recovery lifetimes and reinforcement of polyaniline nanofiber films using carbon nanotubes

“…Therefore, it is reasonable to expect that CNTs and PAni should interact favorably together. In fact it has been reported that CNTs can act as PAni dopants, interacting with both N-H bonding and also quinoid rings on the PAni backbone to increase PAni conductivity [60]. Site-selective interactions between the quinoid ring on the PAni backbone and MWNTs have been reported to facilitate charge transfer between the two components [31].…”

A study of the incorporation of conducting materials into direct-patternable SnO2 thin films formed by photochemical metal-organic deposition

“…The mixed solution was stirred at room temperature for 3 h. MWNTs in the mixed solution were dispersed by a sonicator. 21),28) The solution was then spin-coated at 2,000 rpm for 20 s on substrates of two types. Corning 1737 glass substrates were used to measure crystallinity, as well as optical and electrical properties.…”

“…21) For the fabrication of electronic circuits, micro-patterning is a commonly used process. However, the conventional dry etching process is accompanied by the generation of physical defects, degradation of properties, and pollution from hazardous materials.…”

“…Fig.6, described as the electronic-like band, is considered to be a measure of the degree of delocalization of electrons and thus it is characterized peak of PANI [13]. The band at 1569.95 cm …”
