TI  - Tunable mesoporous lamellar silicas prepared using poly(ethylene 
      oxide-b-L-lactide) and poly(ethylene-b-ethylene oxide-b-L-lactide) block 
      copolymers as templates.

AB  - In this study, we synthesized poly(ethylene oxide-b-L-lactide) (PEO-PLLA) diblock 
      copolymers and poly(ethylene-b-ethylene oxide-b-L-lactide) (PE-PEO-PLLA) triblock 
      terpolymers as templates for the preparation of mesoporous lamellar silicas, 
      possessing single, bimodal, or trimodal pore size distributions, through an 
      evaporation-induced self-assembly (EISA) approach. As templates, we synthesized 
      the diblock copolymers EO114LLA26 and EO114LLA130 and the triblock terpolymers 
      E13EO42LLA26 and E13EO42LLA35 using simple ring-opening polymerization. 
      Small-angle X-ray scattering, transmission electron microscopy, and N2 sorption 
      measurements revealed that the mesoporous silicas displayed the morphologies of 
      either lamellar silica walls featuring a distribution of many short cylindrical 
      mesopores or pure lamellar structures. The morphology was greatly affected by the 
      nature of the template (diblock or triblock copolymer) and the molecular weight 
      of the PLLA segment in the block copolymer.
