Polysilsesquioxane Nanosheets Synthesized in Confined Environment

Abstract

Polysilsesquioxane nanosheets with a thickness of four nanometers and lateral dimensions of several hundreds of nanometers were synthesized by polymerization of a trifunctional monomer in the layer space of montmorillonite as the confined environment.AFM image of a polymethylsilsesquioxane nanosheet.magnified imageAFM image of a polymethylsilsesquioxane nanosheet.

A Novel Wet Chemistry Approach for the Synthesis of Hybrid 2D Free-Floating Single or Multilayer Nanosheets of MS2@oleylamine (M═Mo, W)

“…The hydrodynamic diameters of nanosheets in solution, − as determined by DLS, are in the range of 70–110 nm for MoS 2 @oleylamine (30 min) centered at 94 nm and in the of range 70–170 nm centered at 107 nm for the longer time synthesized WS 2 @oleylamine (90 min) (Figure ). These results are consistent with the SEM observation (Figure ) showing the samples constituted of quasi-spherical suprastructures containing nanosheets (see the TEM images in Figures and ).…”
