Fabrication of Environmental Responsive Copolymer One-dimensional Nanostructures Using Metallogel Fibers as Template†

doi:10.7503/cjcu20140774

Abstract

Abstract:

Using metallogel fibers as templates, environmental responsive copolymer one-dimensional(1D) nanostructures were fabricated via radical copolymerizing N,N'-methylene bisacrylamide(MBA) with different co-monomers, including 4-vinylpyridine(4VP), acrylic acid(AAc) and N-isopropylacrylamide(NIPAM). The compositions, strength and microscopic morphology of the copolymer 1D nanostructures were characterized by means of Fourier-transform infrared(FTIR), rheometer and transmission electron microscopy(TEM). The results indicated that the coordination ability of the co-monomers with the metallogel fibers plays an important role in the yield, strength and morphology of the corresponding copolymer 1D nanostructures. These copolymer 1D nanostructures all showed environmental responsive behavior which enhanced as the increase of molar contents of the co-monomers.

Key words: Copolymer one-dimensional nanostructures, Environmental responsibility, Metallogel, Template synthesis, 4-Vinylpyridine, Acrylic acid, N-isopropylacrylamide, N, N'-methylene bisacrylamide
