Method for preparing a reinforced fluoropolymer composite comprising a surface functionalized nanocrystalline cellulose

摘要

A method of preparing a reinforced fluoropolymer composite is presented, which includes reacting a surface of a nanocrystalline cellulose with a fluorinated electrophile to form a fluoro-functionalized nanocrystalline in which the outer circumference of the nanocrystalline cellulose has been functionalized with fluorinated substrates, and contacting the fluoro-functionalized nanocrystalline cellulose with a fluoropolymer to form a fluoropolymer composite. Also presented is a method of preparing fluoro-functionalized nanocrystalline cellulose, including reacting a surface of a nanocrystalline cellulose with a fluorinated electrophile forming fluoro-functionalized nanocrystalline cellulose in which the outer circumference of the nanocrystalline cellulose has been functionalized with fluorinated substrates, precipitating the fluoro-functionalized nanocrystalline cellulose and isolating and purifying the fluoro-functionalized nanocrystalline cellulose.
