Title: Formation of PS-b-PEO/Silica Films with Flat or Curved Multi-Bilayer Mesostructures of Large-Characteristic Length Scales Prepared by Solvent Evaporation-Induced Self-Assembly

Diblock/silica films with multi-bilayer vesicular mesostructures of large characteristic length scales were synthesized through evaporation-induced self-assembly of PS-b-PEO. The present system is believed to be the first to yield diblock/silica films with multi-bilayer vesicular mesostructures through solvent evaporation-induced self-assembly (EISA). The ready formation in the present system is argued to be the polydispersity of polymer chains.
