An analysis of DC conductivity in terms of degradation mechanisms induced by thermal aging in polypyrrole/polyaniline blends

Thermal degradation mechanism of dodecylbenzene sulfonic acid- hydrochloric acid co-doped polyaniline

“…[3][4][5][6][7] are limited because the conductivity of doped PANI decreases during thermal treatment. The conductivity stability is related to extrinsic factors like surrounding temperatures and intrinsic factors such as the type of protonated acid [8][9][10][11]. Thermal treatment of PANI at different temperatures brings destruction of crystal and chemical structures, decrease of thermal stability and rough and heterogeneous micromorphology, all of which could significantly reduce the conductivity of PANI.…”

The electrical conductivity properties of polythiophene/TiO2 nanocomposites prepared in the presence of surfactants

“…Therefore, the room temperature conductivities are very low, typically <10 À8 X À1 cm À1 [15]. The electronic conductivity of doped materials can be tuned by chemical manipulation of the polymer backbone, by the type and concentration of the dopant material [13,[16][17][18]. Moreover, a polymer-nanocrystal donor-acceptor pathway is known as an electron transport mechanism in the composite systems [19][20][21][22].…”

Preparation of nonwoven mats of electrospun poly(lactic acid)/polyaniline blend nanofibers: A new approach

“…The degradation of the conductivity of the doped PANI in the blend nanofiber mat is attributed, as we mentioned before, to the segregation of the dopants from the polymer backbones . This phenomenon is highly noticeable at high annealing temperatures . The segregation of dopants leads to deprotonation of the emeraldine salts in the blend mat and this can occur during the storage of the mats even under more conservative conditions …”
