Preparation of mesoporous silica nanosheets through electrospinning: a novel scroll mechanism

Abstract

Mesoporous silica nanosheets with high surface area and large pore volume have been produced by a combined process of sol–gel/electrospinning/calcination. The polymer–silica nanofibers were obtained through electrospinning, yet they converted into nanosheets after calcination with the template effect of the dendrimer polyamidoamine. A novel scroll mechanism is proposed to explain this conversion.
