In order to understand dynamical features of amphiphile membranes, we performed neutron spin echo (NSE) experiments in a dilute droplet system consisting of AOT(dioctyl sulfosuccinate sodium salt), D₂O and C₁₀D₂₂ at room temperature, at high temperature, and at high pressure. The bending modulus of membranes was obtained from the model fitting to a theory proposed by Milner and Safran[9] describing diffusive dynamics of droplets. We found that membranes at high temperature was more flexible than those at room temperature, while, those at high pressure was more rigid. This result was consistent with our previous study in a dense droplet microemulsion system.
