Structure and properties of well-defined monoliths of block copolymer/silica nanocomposites using self-assembly |
| 초록 |
This research reports the use of well-defined monoliths to form organic/inorganic nanocomposites with improved optical, thermal and mechanical properties. Mesoscopically ordered, transparent silica-surfactant monoliths have been prepared using amphiphilic triblock poly(ethylene oxide)- poly(propylene oxide)- poly(ethylene oxide) (PEO-PPO-PEO) copolymer species to organize polymerizing silica networks. Mesoscopically ordered silica-block copolymer composites were formed under acidic solution conditions with amphiphilic poly (ethyleneoxide) - poly (propyleneoxide)- poly (ehtyleneoxide) [EO106-PO70EO106] (Pluronic F127) triblock copolymer mixed with butanol and cyclohexane, which act as hydrophobic swelling agents. Mesostructural ordering was determined by Small-Angle X -ray Scattering (SAXS) and transmission electron microscopy (TEM). Optical properties were measured by ultraviolet(UV) spectroscopy. Thermal and mechanical properties were measured by thermogravimetric analysis (TGA) and rheometry. |
