Effect of drying rate on mesoporous silica morphology templated from PEO-PPO-PEO block copolymer assemblies

The authors have shown that the rapid drying process of the nanocomplex of silicate and pluronics is favorable for the formation of closed nanopores, where the enclosure of the pores is promoted due to the solidification of silica prior to the formation of the liquid crystalline phase of pluronics m...

Description
Summary:The authors have shown that the rapid drying process of the nanocomplex of silicate and pluronics is favorable for the formation of closed nanopores, where the enclosure of the pores is promoted due to the solidification of silica prior to the formation of the liquid crystalline phase of pluronics molecular assemblies Here, we report the effect of drying rate on the morphology of mesoporous silicas templated from the pluronic triblock copolymer aggregates, and the formation of closed pores in the mesoscopic structure of the silica.
