Expanding Students' Imagination and Creative Thinking - from Blending Electrospraying to Coaxial Electrospraying

摘要

The problem of how to expand the college students' imagination and creative thinking in their courses is always an important issue puzzling their professional teachers a lot, particularly for those majoring in material science and engineering. In this paper, the history and development of electrospraying (from blending electrospraying to coaxial electrospraying, and to modify coaxial electrospraying) is explored as a useful teaching materials to explain how to provoke the students to imagine and to think in a creative manner about the materials processing engineering. Abundant teaching materials are disclosed from the single-fluid blending and modified coaxial electrospraying processes for expanding the college students' Imagination and creative thinking, which include the technology itself, the reasonable selections of raw materials, the resultant nanoproducts produced during the electrospraying processes, as well as their formation mechanisms. The present article shows the method of feedback teaching for undergraduate students in higher education through scientific research by taking an example.
