مقاله Synthesis, characterisation, and DC conductivity of polyaniline-lead oxide composites : تی پی بین

خلاصه مقاله

The polyaniline-PbO composites of various mass fractions were prepared by in situ polymerisation. The prepared samples were characterised by FTIR, and the dominant peaks confirmed the formation of polyaniline-PbO composites. The SEM study shows a granular agglomerated morphology, and increases with an increase in the lead oxide mass % in polyaniline. Direct current (DC) conductivity (σ DC) was studied as a function of temperature (T). From these studies, it was found that conductivity increased at higher temperatures due to the polarons hopping from one localised state to another. DSC studies reveal, the decrease in peak temperature from 273°C (pure PANI) to 169.2°C, 193.5°C, 218.4°C, 235.2°C, and 224.2°C, respectively for the various mass fractions (10 %, 30 %, 20 %, 40 %, and 50 %) of polyaniline-PbO composites.

Chemical Papers 2013

Chemical Papers is devoted to research in pure and applied chemistry and chemical engineering. At its founding in 1947, the journal presented the achievements of Slovak chemical science. Today, it is a peer-reviewed international journal published in English by the Institute of Chemistry of the Slovak Academy of Sciences, with the support of several other academic institutions. Its interdisciplinary coverage brings chemistry research together with related disciplines, including analytical chemistry; (bio)catalysis; biochemistry; chemical (bio)technology; (bio)chemical engineering; chemical physics; drug chemistry; food chemistry; environmental chemistry; inorganic chemistry; macromolecular chemistry; materials chemistry; mathematical chemistry; medical and pharmaceutical chemistry; nanochemistry; organic chemistry; physical chemistry and more.
