| 摘 要： | 以海藻酸钠为聚合物基体,采用溶胶-凝胶法使正硅酸乙酯在海藻酸钠中水解聚合,形成二氧化硅含量分别为0%、20%、30%、40%的有机/无机互穿网络膜。通过红外(FT-IR)、透射电镜(TEM)、扫描电镜(SEM)及X射线衍射(XRD)对所得样品进行分析表征,结果表明,无机相SiO2的加入对海藻酸钠膜的结构和结晶性能都产生了一定的影响。控制合适的SiO2含量可以获得相容性好的互穿网络膜。

| Abstract: | Novel organic-inorganic interpenetrating polymer networks(IPN) involving sodium alginate and silicon dioxide were synthesized through hydrolysis and condensation of tetraethoxysilane(TEOS) in sodium alginate(SA).The intermolecular interactions and miscibility of the prepared IPN membranes were characterized by Fourier transform infrared spectroscopy(FT-IR),transmission electron microscopy(TEM) and scanning electron microscopy(SEM).The effect of SiO2 on the crystal property of SA was demonstrated by X-ray di... |
