Charge transport and electron localization in polyaniline derivatives

Lowkthin films based on rf plasma-polymerized aniline

“…Optical and semiconducting properties of polyaniline thin films have been the subject of in-depth study by various researchers [10]. Chemical and electrochemical polymerization of aniline is the usual method for the preparation of bulk polyaniline [11,12]. RF plasma polymerization is employed for preparing polyaniline thin films.…”

Characterization of low dielectric constant polyaniline thin film synthesized by ac plasma polymerization technique

“…Chemical methods and electrochemical polymerization of aniline on metallic electrodes is a common method for the preparation of polyaniline thin films. Many researchers [9][10][11][12], including Epstein and co-workers [13][14][15][16] and Kahol and co-workers [17,18], have prepared polyaniline by chemical methods and have carried out dielectric studies in the microwave region. While plasma polymerization technique has been employed for preparing polyaniline thin films, reports on the electrical properties of these films are scanty [19][20][21].…”

A suitable model for emeraldine salt

“…14,15,18,33 A second factor that plays a relevant role in charge transport is the interchain interaction. While the existence of a 3D homogeneous disorder, arising as a consequence of substituent interactions between polymer chains, has been suggested, 34 MacDiarmid and co-workers proposed an inhomogeneous disorder model in which ordered ͑crystalline͒ regions, described by 3D metallic states, are connected through amorphous regions of polymer chains where 1D disorderinduced localization is dominant. 18 Another issue focuses on the way charge transport takes place.…”
