| 제목 | Characterization of a UV Curable Urethane-Acrylate/Clay Nanocomposite System |
| 초록 | Ultraviolet (UV) curing behavior of a urethane acrylate resin system was investigated by FTIR spectroscopy. The conversion of the urethane acrylate resin system during polymerization was calculated from the area of the absorption peak for the vinyl group vibration occurring at 810 cm-1. Urethane acrylate/clay nanocomposites were prepared by reinforcing the resin system with an organoclay. The microstructures of the nanocomposites were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The physical properties of the nanocomposites were examined by universal testing machine (UTM), thermomechanical analysis (TMA), thermogravimetric analysis (TGA) and UV-visible spectrophotometer. Mechanical and thermal properties of the cured films were generally improved with nanoclay reinforcements. Fig. 1. TEM images of the urethane acrylate/clay nanocomposites. |
