Characterization of Polypyrrole
Molecular Crystals and Liquid Crystals, 1985Abstract The renewed interest in the conducting polymer polypyrrole in 1968 was due to the efficient electrochemical synthesis of the polymer which made it possible to grow thin films with appropriate mechanical properties to facilitate the characterization of the polymer.

ABSTRACTConductive polymers such as polypyrrole (Ppy) are potentially useful as an active interface for altering cellular processes and function. Their utilization in medically related applications however have been substantially held back by their non-degradable nature.

Synthesis and characterization of soluble polypyrrole and polypyrrole/organoclay nanocomposites
Journal of Materials Science Letters, 2003As one of the novel conducting polymers, polypyrrole (PPY) has been widely studied due to its good thermal and environmental stability as well as its superior electric conductivity [1, 2], and electrorheological applications [3]. However, PPY is generally insoluble in typical organic solvents because of its strong interand intra-molecular interactions ...

Abstract This chapter presents the history of polypyrrole over the period of 1915–1983. As this material is dependent on the availability of pyrrole, the chapter begins with an overview of the discovery and synthesis of this heterocycle before introducing its initial oxidative polymerization by Angeli in 1915.

Polypyrrole as a thermoplasmonic
2015 International Conference on Computing, Control, Networking, Electronics and Embedded Systems Engineering (ICCNEEE), 2015Thermoplasmonics is a new field in science, that combines nano-thermodynamics and nano-optics. Its main concern is controlling heat generation in nanoparticles due to light absorption. The common definition of thermoplasminics is; metal nanoparticles are efficient nano-sources of heat at surface plasmon resonance (SPR) frequency.

Synthetic studies toward the preparation of several polypyrrolic macrocycles are described. The majority of the research was directed toward the synthesis of a pentapyrrolic analogue (15) of porphyrin (13). The results were surprising, as a meso-substituted porphyrin (63) was the result.
