Phase transitions of nano-scale ordered amphiphilic molecules and di-block copolymers were investigated by the simultaneous differential scanning calorimetry and X-ray diffraction method (DSC-SAXS). Alkyl ammonium type monomer formed bilayer structure on solid surfaces, and bilayer structure was fixed in it's polymer by the irradiation of electrone beam or X-ray at the melting of monomer. The polymerization occurred at the bilayer interface, where monomers established the closest alignment at the melting. The phase transitions of liquid crystalline type amphphilic di-block copolymers were assigned by DSC-SAXS method. The interface between hydrophilic and hydrophobic domains of amphiphic di-block copolymers was characterized by thermodynamic and profile fitting methods.
