【摘要】：本论文的研究内容以多孔阳极氧化铝模板（AAO）为基础，对其形貌进行调控，并将其应用在纳米材料制备和表面增强拉曼散射（SERS）方面。有序多孔AAO模板是一种在纳米至微米尺度内具有长程有序性的多孔材料，其结构参数，，如厚度、孔径、孔隙率、孔间距等，可以通过电解质的种类和电压等简单的电化学参数进行调控，因此作为一种无机材料硬模板，在各种纳米材料的制备中发挥作用。本论文的研究工作分三个部分：利用本小组研发的利用纳米球印刷术在铝表面进行预制图案化制备多级结构AAO模板的方法，在平面基底上制备具有特异周期结构的纳米点阵列，并表征其特异性的光谱特征，与普通AAO模板制备的纳米点阵列进行比较；利用预制图案化方法，制备有序周期超出AAO模板自有序生长窗口的长程有序AAO孔阵列；基于普通周期AAO模板制备的纳米点阵列作为SERS基底，构建具有高灵敏度的SERS微流控芯片实验室系统。
[Abstract]:In this paper, the morphology of porous anodic alumina template (AAO) is regulated and applied to the preparation of nanomaterials and surface-enhanced Raman scattering (SERS). Ordered porous AAO template is a kind of porous material with long order in nanometer-to-micron scale. Its structural parameters, such as thickness, pore size, porosity, pore spacing, etc. It can be controlled by simple electrochemical parameters such as electrolyte type and voltage, so as a hard template of inorganic materials, it plays an important role in the preparation of various nanomaterials. The research work of this thesis is divided into three parts: the method of fabricating multilevel structure AAO template by using nanospheres printing on aluminum surface, and fabricating nano-dot array with specific periodic structure on the plane substrate, using the method of fabricating multilevel structure AAO template on aluminum surface developed by our team. The specific spectral characteristics were characterized and compared with the nano-dot arrays prepared by ordinary AAO templates, and the long-ordered AAO pore arrays with an ordered period beyond the self-ordered growth window of AAO templates were prepared by prefabricated patterning method. A SERS microfluidic chip laboratory system with high sensitivity was constructed based on the nanowires array prepared by ordinary periodic AAO templates as the SERS substrate.
