Synthesis of an Ultraviolet-Cured Polyurethane Acrylate/Silica Hybrid Thin Film Using Sol-Gel Process |
| 초록 |
Polyurethane acrylate (PUA)/silca hybrid thin films were prepared by ultraviolet curing and their thermo-mechanical properties were investigated by a thermo gravimetric analyzer (TGA) and hardness tester. The film forming capability was examined by the manipulation of molar ratio of organic to inorganic components. Under the silica content controlled, highly desirable thin films were achieved and anti-scratch and hardness property of thin film was also enhanced, which indicates that the crosslinked silica particles are homogeneously dispersed within PUA film. The morphology of thin films by the measurement of scanning electron microscope (SEM) and atomic force microscope (AFM) also supports these results, showing that silica aggregates composed of particle diameter of about 150 nm are highly distributed within thin film. |
