Effect of oxyfluorination on electromagnetic interference shielding behavior of MWCNT/PVA/PAAc composite microcapsules

摘要

PURPOSE: A microcapsule for shielding electromagnetic waves, and a producing method thereof are provided to use a multi-walled carbon nanotube with the surface reformed by the oxygenated fluorination treatment. CONSTITUTION: A producing method of a microcapsule for shielding electromagnetic waves comprises the following steps: preparing a microcapsule precursor solution containing a multi-walled carbon nanotube with the surface reformed by the oxygenated fluorination treatment, polyvinyl alcohol, an electromagnetic wave sensitive phosphorus vinyl monomer, a cross-linking agent, and a solvent; and polymerizing, cross-linking and drying the microcapsule precursor solution.
