Summary on Grant Application Form |
|
Building on our expertise of polyaniline synthesis and processing we aim to improve both the electrical and mechanical performance of fibres spun from polyaniline. This will be achieved in two ways. Firstly, advances to the synthesis route of the polymer will be made yielding higher molecular weights with lower polydispersity. The proposed methodology to achieve this is based on our experience of many years. Secondly, following on from our recent discovery of a new functionalised sulphonic acid/solvent system which yields metallic conduction and a co-gelation solvent that allows wet fibre spinning of 'doped' polyaniline, we shall study further combinations of acid and solvent which will allow easier processing, yield higher thermal stabilitya nd better mechanical and electrical properties. We shall pursue ways to achieve liquid crystallity in polyaniline, either via interactions of the acid counter ion, or via alkylation fo the polyaniline in combination with appropriate acids and solvents such that we retain metallic charge transport with the liquid crystallinity. As yet this has not been demonstrated simultaneously. Processing this type of system by wet spinning will give very high degrees of order within the polymer fibres. This should give the highest levels of mechanical and electrical properties possible.
