摘要

以烧结后的二氧化硅光子晶体为模板, 采用溶胶凝胶法向模板间隙填充以甲基丙烯酸(MAA)和丙烯酰胺(AM)为双功能单体, N,N'-亚甲基双丙烯酰胺(BIS)为交联剂的聚合物前驱液, 制备了甲基丙烯酸/丙烯酰胺共聚(PMAM)双单体反蛋白石凝胶光子晶体. 通过紫外可见光谱分析表明, 反蛋白石结构的凝胶膜对pH 响应范围在4.0~7.0 之间. 由于其不受离子强度的影响, 除了可以作为pH传感器外, 还可以作为金属离子及生物小分子等分子印迹光子晶体传感器的基体膜.

Abstract

The polymethacrylic and polyacrylamide inverse opal photonic crystals films (PMAM) have been prepared by using the sintered silica photonic templates, during which the photonic templates are infiltrated by the precursor solutions with the methacrylic and the acrylamide bi-functional monomer, and then polymerized under the UV light (365 nm) and in the end the polymerized films are immersed in HF solutions for the remove of templates. By the analysis of UV/Vis spectra, with the pH increasing, their UV/Vis spectrum peaks are red-shifted at pH=4.0~7.0. But they have no response to the ionic strength, so they can provide the potential matrix membrane for preparing the pH sensors, metal ions and small biomolecules imprinted photonic crystal sensors.
