摘要

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>_{<span style="font-family:Verdana;">1</span>}<span style="font-family:Verdana;">,</span><i><span style="font-family:Verdana;">N</span></i>_{<span style="font-family:Verdana;">10</span>}<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.
