The importance of experimental course in the major of polymer materials was discussed first

and then an innovation experiment was planned

which was named fabrication

structure and property of poly (lactic acid)/calcium sulfate whisker (PLA/CSW) composites via in-situ melt polycondensation. On the basis of students' consulting literatures

understanding the basic theories and designing the proper experimental routes

PLA/CSW composites characterized by uniform dispersed whisker and well-bonded interfaces were prepared successfully. The molecular weight

interfacial morphology and crystallization behavior of the composites were measured

and finally a copy of well-organized experimental report for every student was required. This innovation experiment was related to various knowledge points derived from organic chemistry

polymer chemistry

polymer physics

composite materials

surface and interface of materials and modern materials analysis and testing technology

etc. The whole process was consisted of literature consultation

data analysis

collaboration

group discussion and writing the experimental reports. It gave the positive contributions to the improved all-round abilities of students

as will lay the solid foundation for their developments in future.
