Abstract

Now that well-ordered nanoparticles can yield a promising performance in various fields, spatially regular arrangement of particles is a key requirement for nanoparticle-embedded engineering materials and devices. Here, we demonstrate a feasible, robust method where nanoparticles can be regularly distributed and encapsulated. Polymeric substrates with different sized nanoholes were injection-molded by controlling mold-wall temperature in a spatial and temporal manner. A hybrid structure of nanoparticles was constructed by binding quantum dots with metal nanoparticles, and they were filled into the nanoholes using the knife coating process. The morphology of the nanostructure prepared via the molding process and the nanoparticle array was analyzed using a scanning electron microscope and a transmission electron microscope. Fluorescence emission of the hybrid nanostructure was measured. The finding showed that the strategic approach introduced in this study could allow fabrication of hybrid nanoparticle structures with good processability and productivity. © 2024 Society of Chemical Industry.

采用注射成型纳米结构制备杂化纳米粒子阵列
由于有序的纳米颗粒在各个领域都有着广阔的应用前景,因此纳米颗粒在空间上的有序排列是纳米颗粒嵌入工程材料和器件的关键要求。在这里,我们展示了一种可行的,稳健的方法,纳米颗粒可以有规律地分布和封装。通过对模壁温度的时空控制,对具有不同尺寸纳米孔的聚合物基板进行了注射成型。通过将量子点与金属纳米粒子结合,构建了纳米粒子的杂化结构,并采用刀涂工艺将其填充到纳米孔中。利用扫描电镜和透射电镜对成型工艺制备的纳米结构和纳米颗粒阵列的形貌进行了分析。测量了杂化纳米结构的荧光发射。研究结果表明,本研究中引入的策略方法可以制造具有良好可加工性和生产率的混合纳米颗粒结构。©2024化学工业学会。
