We propose to use SANS to probe the self organised formation of P3HT nanowires in a solution of deuterated chlorobenzene over a 48 hr period in order to better understand the dynamics of the growth process. Nanowire formation in P3HT solutions is significant because of P3HT's applications, especially in photovoltaic devices and chemical vapour sensors. P3HT nanowires will help to improve these devices and understanding their growth is vitally important to tailoring the nanowires to their designated application. Other methods such as UV-Visible spectroscopy and AFM do not allow us to fully probe the solution as the wires grow and as such we believe SANS results will enhance our understanding of the early growth processes. This experiment will be complementary to our Offspec proposal, which will measure the larger nanowire dimensions after longer periods of growth.
