要实现对氧化锌纳米线的原位拉伸或压缩,需要通过化学实验得到稀疏的、长径比符合要求的纳米线。本研究在大量文献调研[1]和探索性实验基础上,以Au为催化剂在硅片基底上制备氧化锌纳米线。由于退火温度、溶液浓度、水浴温度和水浴时间对制备的纳米线的形貌和长径比影响很大,单一因素实验不能筛选最优实验方案,制备最佳长径比的纳米线必须用统计学理论作指导。本文提出了一个新的实验方法——正交实验,是一种科学的统计分析和设计方法,它在减少实验数量的同时,对制备高长径比氧化锌纳米线的影响因素排序并筛选出最优实验方案。
To achieve the in-situ stretching or compressing of ZnO nanowires, we need to obtain the sparse, aspect ratio nanowires through chemical experiments. In this study, a large number of literatures [1] and exploratory experiments based on the preparation of Au as a catalyst on a silicon substrate ZnO nanowires. Due to the influence of annealing temperature, solution concentration, water bath temperature and bath time, the morphology and aspect ratio of the prepared nanowires are greatly affected. Single factor experiments can not screen the optimal experimental scheme. The nanowires with the best aspect ratio must be statistically analyzed Learning theory as a guide. In this paper, a new experimental method, Orthogonal Experiment, is a scientific statistical analysis and design method. While reducing the number of experiments, the factors affecting the preparation of high aspect ratio ZnO nanowires are sorted and screened out Optimal experimental program.
