Covalent functionalization of black phosphorus nanoflakes by carbon free radicals for durable air and water stability†
Abstract
This work developed a simple and efficient method to covalently functionalize black phosphorus nanoflakes (BPNFs) with carbon free radicals from azodiisobutyronitrile (AIBN) molecules. BPNFs after successful modification (BPNFs–AIBN) not only had good stability in air and aqueous solution, but also still maintained good optical properties.
