What are the methods of preparing nanomaterials?

05 May 2018 1 1K Report

1. Mechanical grindingi.e top down method : involves structural decomposition of coaser grained structures

2.Wet chemical synthesis, here single crystals are etched in an aqueous soln, sol gel is an example.

3. Furnace heating , examples incude but not limited to laser ablation, micro wave plasma, flame assisted ultrasonic spray pyrolysis..........
