| 摘 要： | 多孔材料由于孔道相互连通、比表面积大等特性而在吸附、离子交换，特别是在催化等领域中具有广泛应用价值．当孔道均匀且有序排列时，如果其间距与可见光波长相匹配时，则可对光产生调制作用，得到光子带隙材料，在未来的信息处理等方面将发挥重要作用．目前，人们以单分散的微粒有序排列的胶体晶为模板制备了各种有序大孔材料，

| Abstract: | The monodisperse silica particles self-assembled colloidal crystals were used as templates to synthesize pH value and temperature responsive ordered macorporous hydrogels. The ordered structure arranged by the uniform pores and the pore-pore interconnectivity through the window channel is confirmed by SEM characterization. UV-Vis-near IR absorption experiment result reveals that the wavelength at the stop band peak is tunable within the whole visible spectrum via simply altering some parameters such as pH value and light incidence angle. This finding allows to design frequency-tunable photonic band gap materials. |
