Synthesis Method of Gold Nanosheets in Hyperswollen Lyotropic Lamellar Phase

Abstract

We have succeeded in the fabrication of gold nanosheets in a hydrophilic space inside highly separated bilayers in a hyperswollen lamellar liquid crystalline phase. The nanosheets can only grow in the in-plane direction due to the inhibition of the out-of-plane growth rather than the anisotropy of growth rates. We found that the width of the obtained gold nanosheets is proportional to the Reynolds number because the area of the bilayer in the hyperswollen lamellar phase depends on shear stress.
