What type of polymer is polyacetylene?
Polyacetylene is an archetypal conjugated polymer and consists of a long chain of carbon atoms with alternating single and double bonds.
Is polyacetylene a semiconductor?
4.1 Polyacetylene Polyacetylene is often taken as a prototype for the class of conjugated organic polymers. [199, 200], with polyacetylene as the active semiconductor compound. In that case the polymer was formed from a solution-processible precursor polymer.
What is Pani in chemistry?
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.
What is doped polyacetylene?
These highly conductive forms of polyacetylene were achieved via oxidation or reduction of the neutral polymer and such redox modified conjugated polymers are often referred to as doped materials in analogy to the doping of inorganic semiconductors such as silicon.
What is polyacetylene used for?
4.4 Conducting Polymers. Polyacetylene is the simplest conjugated organic polymer and hence is used extensively to model mechanisms of electrical conduction for such systems (59).
Is polyacetylene a conducting polymer?
1 Highly conductive materials. Polyacetylene (PA) was the first polymer exhibiting high conductivity comparable with metals if exposed to oxidising agents like iodine vapour. Oxidation forms charge carriers on the conjugated polyene structure, especially of p-type conductivity.
Is PANI water soluble?
Pure polyaniline (PAni) is insoluble in water. Water-soluble complexes of PAni with different of cellulose derivatives were successfully synthesized by using chemical oxidation polymerization of aniline in aqueous solution of cellulose derivatives.
How is polypyrrole made?
Polypyrrole (PPy) was synthesized by chemical oxidative polymerization technique using pyrrole monomer and different oxidants. The chemical polymerization was carried out in a beaker with 100 ml of distilled water by mixing different molar ratios of pyrrole monomer, an oxidant, and a surfactant.
What are the isomers of polyacetylene?
PA exists in two isomeric forms: trans and cis, see Fig. 13.3. The trans form is the thermodynamically stable form at room temperature.
Why is PANI conductive?
PANI (Fig. 3.12) is a very promising intrinsically conducting polymer because of its easy synthesis, low cost, tunable properties, high polymerization yield, and environmental stability. PANI is also known as aniline black and it exists in various forms depending on its oxidation levels.
Is polypyrrole water soluble?
Synthesis of water-soluble polypyrrole. The water-soluble polymers were synthesized based on a two-step polymerization/doping procedure. First, pyrrole (2.9 mmol, 195 mg) was added to 35 mL water containing 2.9 mmol of different dopants under vigorous stirring.
