Synthesis and Structural Analysis of a crystalline and amorphous diblock copolymer in thin films |
| 초록 |
A diblock copolymer of crystalline polyethylene (PE) and amorphous poly(methyl methacrylate) (PMMA), PE69-b-PMMA92, was synthesized; this polymer is thermally stable up to 270 °C. The morphological structures of thermally annealed nanoscale thin films of the copolymer were investigated in detail at various temperatures by using in-situ grazing incidence X-ray scattering (GIXS) with a synchrotron radiation source. Quantitative GIXS analysis found that the PE and PMMA blocks undergo phase separation to produce a vertically oriented hexagonal PE cylinder structure in the PMMA matrix that is very stable up to around 100 °C (which is the onset temperature of PE crystal melting and PMMA glass transition); over the range 100–200 °C, slight variations with temperature in the cylinders’ dimensions and orientation were observed. |
