Abstract

See full text

Disclosed is a method for preparation and activation of a super hydrophobic electret nanofibrous filter material for cleaning PM2.5, comprising the steps as follows: (1) dissolving polymer powders and resin into a corresponding solvent so as to prepare a polymer solution, then stirring on a magnetic stirrer and standing for use; (2) in order to reinforce the electrostatic effect of the fiber, before preparing the polymer solution, adding in organic electret nanoparticles into the solvent, then oscillating with an ultrasonic oscillator; (3) in order to reinforce the super hydrophobic effect of the filter, spraying a low surface energy solution on the prepared nanofiber with a designed nozzle to carry out modification.
