Design of Comprehensive Scientific Research Experiment on Preparation and Two-dimensional Laser Diffraction of PS Microspheres Array

To promote the cultivation of undergraduates’ scientific research innovative thinking and practical ability, and to practice the collaborative education mechanism of “research and teaching”, the Langmuir-Blodgett (L-B) self-assembly technology to prepare a highly ordered polystyrene (PS) microspheres array experiment is taken as an example, which requires students to analyze the morphology, degree of order and laser diffraction of the as-prepared samples. This comprehensive experiment covers multiple knowledge points such as the principle of self-assembly, structural fabrication, morphology characterization and two-dimensional laser diffraction. It is beneficial for improving student’s scientific consciousness and practical ability, and it provides an advantageous exploration for cultivating new talents with innovative scientific thinking.
