| Abstract: | The degradation behaviour of electrochemically prepared polythiophene and polypyrrole has been studied by thermal gravimetric
analysis technique. Studies on both the polymers show that they are more stable than polyacetylene but still undergo degradation
reactions which involve two steps, viz. loss of dopant and then degradation of polymer backbone. The general features of degradation
mechanisms are discussed. |
