Abstract
A dispersion includes core-shell-type fluorine-based resin particles having improved flowability and cohesion properties. The particles, a mixture or slurry (dispersion) including the particles, and a preparation method for the particles, mixture, and slurry. The particles each have an acryl monomer added to a perfluorinated polymer particle dispersion so as to have a perfluorinated polymer core and an acrylic polymer shell.
Claims7
Composite core-shell particles having perfluorinated resin core-polymethylmethacrylate-based resin shell, which is prepared by emulsion polymerization of an acryl monomer using an emulsifier of the following Chemical Formula 1, in a perfluorinated resin particle slurry:
- R—(—O—C2H4—)n—OH [Chemical Formula 1]
- wherein R is a C8 or higher branched alkyl group, and n is an integer of from 5 to 15,
- wherein the polymethylmethacrylate-based resin forming the shell comprises 70 wt % or more of the methylmethacrylate monomer, based on the total weight of the polymethylmethacrylate-based resin, and
- wherein the composite core-shell particles have a cohesive energy value of 10 mJ/g or less and a total surface energy value of 2000 mJ or less, as measured using a flow rheometer.
