Tri-block copolymers offer an excellent model system for the study of crystallization in the bulk as well as close to interfaces. It is known that the structures formed by this systems are highly sensitive to the surface energy of the solid surface. The idea of the present experiment is to draw a complete picture of the crystallization process of Pluronic micelles close to silicon substrates. This will be achieved by exploiting the wavelength dependence in the penetration depth for a time of flight gracing incident small angle scattering study and by separating the specularly scattered intensity from the small angle scattering by use of spin echo techniques in neutron reflectometry.
