Method in physical chemistry ( Material)

Z. (a) Name a conducting polymer and draw its chemical structure.
(b) With the use ofdiagrams, explain the mechanism by which a conducting
polymer can be grown. Explain how it conducts charge.
(c) Using an example, explain how the properties of a conducting polymer can
be used in a device.
(d) In the context of paints, saturated polymers are frequently used for corrosion
protection coatings. Explain why polymer coatings are brittle and crack at
very low temperatures and how this can exacerbate corrosion of a mild steel
substrate. For one additive, discuss its role in reducing the rate of corrosion

(e) The incorporation of carbon fibre within a polymer matrix can lead to enhanced
polymer strength. Explain with diagrams how the bonding between the fibres
and the polymer resin can affect the mechanical properties of the composite.
