We propose to use the new GI-SANS set-up on FIGARO to complete surface morphology diagram of the liquid/air interface of Pluronic P85 with temperature. P85 forms a variety of structures which are very sensitive to temperature; a phase change can occur in 1 deg C so the method of change will also be investigated. The temperature ramp rate is crucial in this experiment to observe the routes of change. The macroproperties can then be suitably correlated to the microstructures which are vital in many applications; from industrial processes to the biomedical sector.
