%X Methyl
methacrylate (MMA) was successfully grafted onto cellulose nanofibers (CNFs) at
room temperature in an emulsion system using a diethyl(1,10-<span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\">phenanthroline </span><i><span style=\"font-family:Verdana;\">N</span></i><sub><span style=\"font-family:Verdana;\">1</span></sub><span style=\"font-family:Verdana;\">,</span><i><span style=\"font-family:Verdana;\">N</span></i><sub><span style=\"font-family:Verdana;\">10</span></sub><span style=\"font-family:Verdana;\">)zinc(</span></span><span style=\"font-family:Verdana;\">II</span><span style=\"font-family:Verdana;\">) complex (Phen</span><span style=\"font-family:Verdana;\">-</span><span style=\"font-family:Verdana;\">DEZ)
with oxygen as the radical initiator. The effects of reaction temperature,
initiator concentration, and monomer content on the grafting reaction were
investigated. The molecular weight of the non-grafted PMMA, which was produced
during graft polymerization, was more than 1 million, as determined by size
exclusion chromatography. The PMMA-grafted CNFs were analyzed by Fourier
transform infrared spectroscopy, thermogravimetric analysis, and scanning
electron microscopy, which confirmed the grafting of PMMA on the nanofiber
surface. The study presents a strategy for the grafting of high-molecular
