제목 Studies of the Miktoarm Star Polymers’ Thin Film Morphologies using Grazing Incidence Small-Angle X-Ray Scattering
초록 A series of interesting miktoarm star polymers composed of a highly rigid and crystallizable poly(n-hexyl isocyanate) (PHIC) arm and one to three flexible and crystallizable poly(-caprolactone) (PCL) arms’ thin film morphologies were investigated using synchrotron grazing incidence X-ray scattering methods. The PCL homopolymer and star polymers formed horizontally oriented lamellar structures in toluene-annealed films. Interestingly, the structural parameters associated with the star polymer films were significantly influenced by the exceptional rigidity of the PHIC arm chain and by the number and length of the PCL arms. The horizontal lamellar structures formed in the miktoarm star polymer films were quite different from those observed in common flexible block copolymer specimens. This study demonstrated that a miktoarm star polymer system consisting of rigid and crystallizable arms could form thin films with a morphology that is suitable for specific target applications.
