AB  - Block copolymers are widely used in industry. For scientific interests their 
      aqueous solutions offer a model system for the investigation of crystallisation 
      as the macromolecules agglomerate for elevated concentrations into micelles, 
      which crystallise when a critical volume fraction is reached. We report on 
      grazing incidence small angle neutron scattering (GISANS) or near surface small 
      angle neutron scattering (NS-SANS) as an experimental tool to investigate the 
      micelle crystallisation close to interfaces with different chemical termination. 
      We find that in general crystallization is suppressed at a repulsive surface and 
      favoured at an attractive one. Furthermore we show that the crystallization close 
      the interface can be controlled by the micelle stability, resulting from the 
      different composition and length of the monomers. The effect of the interface is 
      found more important for a high micelle stability, whereas for a low stability it 
      is shadowed by adsorbed monomers.
