Conducting polymers are rapidly gaining attraction in new applications with increasingly processable materials with better electrical and physical properties and lower costs. The new nano-structured forms of conducting polymers particularly, augment this field with their higher surface area and better dispersability.
In general, two categories of applications are proposed for conducting polymers. Static applications rely upon the intrinsic conductivity of the materials, combined with their processing and material properties common to polymeric materials. Dynamic applications utilize changes in the conductive and optical properties, resulting either from ...
The general strategy for the synthesis of conducting redox polymers is to attach a redox active group to a monomer (or a trimer) of the respective conducting polymer.These monomers, which are often EDOT derivatives, are subsequently polymerised either by electropolymerization or by chemical oxidative polymerisation (eg. with FeCl 3 or Fe(OTs) 3).
Figure 2. Polymer photovoltaic cell using transparent conducting polymers. Conductive polymers were reported in the mid the 20th century as derivatives of polyaniline. [22] Research continued on such polymers in the 1960s and 70s and continued into the turn of the 21st century. [23] [24] Most conductive polymers are derivatives of polyacetylene ...
Polyaniline (PANI) is a conducting polymer and organic semiconductor of the semi-flexible rod polymer family. The compound has been of interest since the 1980s because of its electrical conductivity and mechanical properties. Polyaniline is one of the most studied conducting polymers. [2] [3]
Poly(p-phenylene vinylene) (PPV, or polyphenylene vinylene) is a conducting polymer of the rigid-rod polymer family. PPV is the only polymer of this type that can be processed into a highly ordered crystalline thin film. PPV and its derivatives are electrically conducting upon doping.
Conducting polymers are of interest for solution-processing for film-forming conductive polymers. [6] Therefore, attention has shifted to other conductive polymers for application purposes including polythiophene and polyaniline. Molecular electronics could also be a potential application of conductive polyacetylene.
Polypyrrole (PPy) is an organic polymer obtained by oxidative polymerization of pyrrole. It is a solid with the formula H(C 4 H 2 NH) n H. It is an intrinsically conducting polymer , used in electronics, optical, biological and medical fields.
