Photoinduced Doping and Photolithography of Methyl-Substituted Polyaniline

Advanced syntheses and microfabrications of conjugated polymers, C60-containing polymers and carbon nanotubes for optoelectronic applications

“…P(3AT)s) through patterned photocrosslinking (or crosslinking by electron beam) followed by a solution-based development process [542±547]. Furthermore, conducting patterns could also be made from a mixture of the soluble base form of polyaniline and a photoacid generator, which photochemically generated the acidic dopants required for generating conducting patterns of the insoluble polyaniline salts [548,549]. The solubility of the conducting polymers used in these approaches was acquired by covalently bonding conjugated polymers with soluble side-groups or polymeric block chains, which often reduced the conductivity as discussed in the subsection`By Substitution'.…”

Direct laser interference patterning of poly(3,4-ethylene dioxythiophene)-poly(styrene sulfonate) (PEDOT-PSS) thin films

“…Reactive methods usually involve radiation to locally initiate a chemical reaction in a polymer or precursor-polymer film [6,7], while non-reactive patterning methods involve lithographic techniques [8][9][10] to pattern a polymer in its final form without the requirement of further chemical or thermal treatments. The availability of powerful lasers operating in both the visible and UV wavelengths has made it technically feasible to structure electrically conducting polymers with high-resolution.…”

Preparation and magnetic properties of ZnCuCrLa ferrite and its nanocomposites with polyaniline

“…that PANI has two characteristic absorption bands at around 333 and 616 nm. The absorption band around 333 nm is attributed to π-π * transition of the benzenoid ring [26,27], while the band around 616 nm corresponds to charge transfer from the benzenoid rings to the quinoid rings [28,29]. It is found from Figs.…”
