Abstract

The technology of preparing lithium-ion battery separator of polypropylene via a dry uniaxially stretching process involves a lot of contents of

polymer physics

from multiple chapters

such as Structure of polymer chains

Condensed phase

Molecular motion and transitions

Viscoelasticity

Yield and fracture

Rheological property

Surface and interface

etc. Therefore it is very suitable for the case teaching. This paper discusses how to combine the knowledge points involved in the manufacture with the case teaching of

polymer physics

. The microstructure of the condensed phases of polypropylene in each section of manufacture and the effects of process parameter change on the structure and properties are analyzed. Furthermore

the discussion is made about the technology of biaxially stretching process and the technology of hydrophilic modification of separator of polypropylene based on the knowledge related to

polymer physics

. It is helpful for the students to master the relevant knowledge flexibly and improve their ability in engineering practice and creativeness.
