分别以4-乙烯基吡啶(4VP)、丙烯酸(AAc)和N-异丙基丙烯酰胺(NIPAM)为共聚单体，以金属凝胶纤维为模板，通过自由基共聚合得到了具有环境响应性的共聚物一维纳米结构.采用红外光谱( FTIR)、流变仪和透射电子显微镜( TEM)等表征了共聚物一维纳米结构的组成、强度及微观形貌.结果表明，共聚单体与模板的配位能力强弱对所得到的共聚物一维纳米结构的产率、强度和形貌有很重要的影响.3种共聚物都具有相应的pH响应性和温度响应性，并且共聚单体含量越高，响应性越明显.

Using metallogel fibers as templates, environmental responsive copolymer one-dimensional(1D) nanostructures were fabricated via radical copolymerizing N,Nˊ-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 1 D nanostructures all showed environmental responsive behavior which enhanced as the increase of molar con- tents of the co-monomers.
