摘要

为了进一步培养本科生的实践创新能力，面向高分子科学与工程专业高年级本科生设计了高分子微流体和相分离协同调控纤维表面微纳结构的前沿实验。实验结合了纤维表面高分子微流体产生的瑞利不稳定性现象，以及反溶剂诱导的相分离过程，实现了尺寸和孔结构均可控的纺锤节纤维连续化制备。实验教学过程中，学生不仅熟悉了微流控技术的基本原理和发展动态，还全程参与了溶液制备、微流体控制、相分离过程控制以及集水性能测试等实验环节，掌握了高分子微纳加工技术和形貌结构表征方法。该实验教学很好地促进了学生对高分子物理、流变学、高分子成型加工等不同学科基础知识的融会贯通，有效培养了学生的创新思维、科研潜力和团队协作能力。

Abstract

To further cultivate the practical innovation ability of undergraduate students majoring in polymer science and engineering

an innovation experiment was designed for senior undergraduate students

which combined microfluidics and phase separation for polymeric fluids on fibers. The experiment harnessed the Rayleigh-Plateau instability phenomenon generated by polymeric microfluids on the surface of fibers and the antisolvent-induced phase separation process

to achieve the continuous preparation of spindle-knot fibers with controllable size and pore structure. During the experimental teaching process

students not only familiarized themselves with the basic principles and development trends of microfluidic technology

but also participated in the entire experimental process including solution preparation

microfluidic control

phase separation process control

and water collection performance testing. As a result

they understood and mastered polymer micro-/nano-fabrication technology and morphology characterization methods. This experimental teaching has effectively promoted students to integrate basic knowledge in different disciplines such as polymer physics

rheology

and polymer molding and processing

and effectively cultivated their innovative thinking

research potential

and teamwork ability.
