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.
The sintered silica photonic crystal was used as a template to fill the template gap with methacrylic acid (MAA) and acrylamide (AM) as a bifunctional monomer and N, N’-methylene bis-propylene (BIS) was used as the precursor of the cross-linking agent to prepare the PMMA double-monomer inverse opal gel photonic crystal.Ultraviolet spectroscopy showed that the anti-opal structure gel film The pH response range is between 4.0 and 7.0. Since it is not affected by ionic strength, it can not only be used as a pH sensor, but also as a matrix film for molecularly imprinted photonic crystal sensors such as metal ions and biological small molecules.
