纳米阵列的可控制备技术在实验教学中的开展

由于存在师资、设备等条件的限制,研究型实验教学通常难以开展。本文探究了基于纳米阵列可控制备的研究型实验教学。本文探究的纳米阵列可控制备设备要求低,实验步骤简单易行。首先通过改变实验条件,可以制得不同尺寸的纳米球。再利用制备好的纳米球,通过水/空气界面提取法得到周期性的纳米阵列。基于纳米阵列可控制备的研究型实验教学不仅使学生更加深刻理解纳米材料,激发学生的科研兴趣。

Fabrication of Nano-array Carried out in Experimental Teaching

This article explores the research of two-dimensional（2D） colloidal crystals with compact hexagonal structure.Experimental teaching of research is an important element of the experimental teaching reform.However,due to the constraints of teachers and equipments,the experimental teaching of research is often difficult to carry out.This article introduces a simple experimental procedure to fabricate nano-array.Through experiment teaching,students can control the particle size of nanospheres and fabricate nano-array.This can stimulate undergraduates＇ interest in scientific research.
