Structure Analysis of Poly(n-hexyl isocyanate)-Poly(e-caprolactone Miktoarm starpolymer in Thin film |
| 초록 |
A series of miktoarm star polymers, [poly(nhexylisocyanate)(12K)]−[poly(ε-caprolactone)1−3(5K)] (PHIC−PCL1−3), were investigated to examine the polymers’ thermal properties and nanoscale thin film morphologies. The resulting thin film morphologies were examined in detail using synchrotron grazing incidence X-ray scattering (GIXS) measurements and quantitative data analysis. All of the miktoarm star polymer films formed vertically well-oriented lamellar structures. The PHIC lamellae consisted of a mixture of horizontal and vertical multibilayer structure domains, as observed in the PHIC homopolymer film. The PCL lamellae formed fringed micelle-like crystals and/or highly imperfect folded crystals that differed significantly from the structures found in a PCL homopolymer film composed of typical folded lamellar crystals. These PCL crystals were formed with a mixture of vertical and horizontal orthorhombic lattices. |
