Abstract
The present invention relates to preparation of fluorinated core-shell particles with water and oil repellency, and more particularly, to preparation of emulsion-type coating material with good water and oil repellency using only small amount of expensive fluorinated monomers, which comprise a shell wherein a large amount of hydrophobic fluorinated monomers are included and a core wherein no fluorinated monomers are included.
