摘要

基于专业认证中能力培养的导向，设计了一组创新型综合实验——“PLA/Fe

纳米复合材料的制备及微波发泡性能”。要求学生在认真分析选题、查阅文献资料并明确实验原理的前提下，设计并优化了实验方案，成功地制备了纳米粒子均匀分散且界面结合良好的PLA/Fe

纳米复合材料，考察了其界面结合、分子量以及微波加热发泡能力。通过建立过程管理和结果考核相并重、能够贯穿整个实验进程的创新评价体系，充分调动了学生参与实验课程的主观能动性，同时能及时获取学生的反馈并制定相应的整改措施，提高最终实验教学质量，达到预期培养目标。

Abstract

With the guidance of the competency-based training of engineering education accreditation

a set of innovative and comprehensive experiments

which was named the fabrication of poly (lactic acid)/ferriferous oxide (PLA/Fe

)nanocomposites and its microwave-assisted foaming ability

were proposed. On the bases of students' understanding of the topic

consulting the literature and preparing the essential principles

the optimized experimental routes were drawn properly. The PLA/Fe

nanocomposites characterized by uniform dispersed particles and well-bonded interfaces were fabricated successfully

and then investigations on interface structure

molecular weight as well as microwave-assisted foamability of the composites were carried out. To promote the subjective activity of students participating in the experimental courses

a novel evaluation system

which is combined by process management and result assessment and concerning every step of the whole experiments

has been established. On the other hand

the proper corrective actions could also be made according to feedback from the students

finally improving the qualities of experimental teaching and achieving the expected training targets.
