| Abstract |
Mesoporous Silicas were prepared in the presence of several kinds of PLGA-PEO-PPO-PEO-PLGA pentablock copolymers using evaporation-induced self assembly (EISA) process. Pluronic F68, F127, and F108 triblock copolymers were used as macro-initiators to prepare pentablock copolymers with different length scales. We tried to find any relationship between variation of pore size and the length scale of pentablock copolymers. We present synchrotron SAXS patterns to investigate characteristic pore sizes, BET sorption and TEM images to clarify pore structure and sizes. Also, we investigate solid state 29Si NMR for chemical nature of siloxane bonds. |
