采用加热回流法制备了硬脂酸(SA)和聚乙烯吡咯烷酮(PVP)混合改性的Ag/ZnO纳米复合材料。傅里叶变换红外光谱(FT-IR)表明,有机SA/PVP键合到Ag/ZnO纳米晶表面,使纳米结构的润湿性由亲水性转变为疏水性。改性后的Ag/ZnO纳米结构被证实是有效的拉曼基底,与普通亲水性Ag/ZnO基底相比,由于疏水缩合效应,用于检测Rh B分子的信号增强了3倍。预期修饰的Ag/ZnO纳米粒子具有基于SERS的分子快速检测的潜力。
Ag/ZnO nanocomposites modified by a mixture of stearic acid (SA) and polyvinylpyrrolidone (PVP) were obtained using a heating reflux method. Fourier transform infrared spectroscopy (FT-IR) suggests that organic SA/PVP was bonded onto the surface of Ag/ZnO nanocrystals, converting the wettability property of the nanostructures from hydrophilic to hydrophobic. The modified Ag/ZnO nanostructures were confirmed as effective Raman substrates, with a 3-fold signal enhancement compared to the ordinary hydrophilic Ag/ZnO substrate for detecting Rh B molecules due to the hydrophobic condensation effect. It is expected that the modified Ag/ZnO nanoparticles have potential for SERS-based rapid detection of molecules.
