Abstract

The final morphology of the lamellar silsesquioxane produced from the (EtO)3Si(CH2)3NHC(=O)NH(CH2)12NHC(=O)NH(CH2)3Si(OEt)3 (P12) precursor using an acid-catalyst and a large excess of water was changed from rigid platelets (L12) to micro-objects that resemble sea sponges (L12D) upon simple mixing with dimethylsulfoxide (dmso). The microstructural modifications observed were ascertained by several techniques. A mechanism for the morphology tuning based on the polarity of the solvent mixture is proposed.
