Preparation of Functionalized Ramie Fiber via Atom Transfer Radical Polymerization

摘要：

The surface grafting of tertiary amine 2- (dimethylamino) ethyl methacrylate (DMAEMA) to ramie fiber was carried out via atom transfer radical polymerization (ATRP). The quantitative Characterization results reveal that the poly (DMAEMA) (PDMAEMA) was successfully immobilized on the surface of ramie fiber in a controlled/living mode. As a demonstration of applications, the modified fiber was dyed with C. I. reactive red 2. The dye uptake, which almost linearly increased with the increase in molecular weights of the PDMAEMA attached on ramie fiber, was raised to be over 15 times of the raw fiber. The reason is explained as that the tertiary amines in PDMAEMA were protonated into quaternary amines, which facilitate the fix of the anionic dye on the ramie fiber.
