摘要：

The regular graft copolymer, BC-g-PGMA was synthesized via electron transfer for atom transfer radical polymerization (ARGET ATRP), using bacterial cellulose aerogels with bromide side-group (BC-Br) as macroinitiator and N, N, N', N, 'N″-pentamethyldiethylenetriamine (PMDETA)/copper(II) bromide (CuBr2) as catalytic system, vitamin C as reducing agent and glycidyl methacrylate (GMA) as comonomer. Spectroscopy (EDS) macroinitiators element content was determined and by infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscope (SEM), thermo-gravimetric analysis (TGA), the structure and properties were characterized. The results indicate that the grafting polymerization of GMA on BC aerogels can be controlled; macroinitiators Br elements can reach 6.77%; the fiber diameter increases after GMA graft polymerization and the coating is formed in the fiber surface layer; the initial thermal decomposition temperature increases from 205℃ to 246℃, and the thermal stability is improved. © 2018, Editorial Board of Polymer Materials Science & Engineering.
