Cellulose nanofibrils (CNFs) are sustainable and non-toxic nanofillers for fabrication of polymer nanocomposite with high performances due to its three-dimensional anisotropy and high mechanical strength. A critical challenge in fabricating high-performance polymer-CNF nanocomposites is dispersion of CNFs in a polymer matrix. Here, we report a facile preparation process for polypropylene / CNF composite. CNFs are adsorbed on micron to nanometer-sized polypropylene particles. This method assures fine dispersion and enhances filler-loading, and provides a general way for a minimized use of solvent for the production of high-quality polymer / CNF nanocomposites. |
