Abstract (en)
[origin: US2014106165A1] This disclosure provides for a process for making an oil and grease resistant cellulosic material such as paper and paperboard, the process comprising applying a homogeneous aqueous dispersion of fluorochemical surface-modified nanoparticles to a cellulosic substrate to form a treated cellulosic substrate, and subsequently drying the treated cellulosic substrate to form an oil repellent cellulosic material. Fluorochemicals that can be used to modify the nanoparticles include fluoroalkylsilanes, ionic fluorochemicals, or fluorinated polyacrylate obtained by seeded emulsion polymerization of fluorinated acrylates on the nanoparticles. Paper, paperboard and cellulose fiber articles that have been modified by the disclosed processes have improved oil and grease resistance properties.
