Bulk quantities of nanocarbons having pre-selected morphology can be synthesized in a simple and rapid microwave heating approach directly from conducting polymers.

We study the band gap in some semi-conducting polymers with two models: Hückel molecular orbital theory and the socalled free electron model. The two models are directly related to spectral theory on combinatorial and metric graphs. Our numerical results reproduce qualitatively experimental results and results from much more complex density-functional calculations. We show that several trends c...

Polymers can be prepared using chemical and/or electrochemical methods of polymerization (see Chap. 2), although most redox polymers have been synthesized by chemical polymerization. Electrochemically active groups are either incorporated into the polymer structure inside the chain or included as a pendant group (prefunctionalized polymers), added to the polymer phase during polymerization, or ...
