Abstract Details

2018, Master of Sciences, Case Western Reserve University, Macromolecular Science and Engineering.
Chapter 1: Fibrous tape PVDF/PA6I/6T with 9% PS as separating layer was developed for the application of battery separator produced from a novel co-extrusion technique. After delaminating by high-pressure water jet, the separating layer was removed and formed a fibrous membrane with surface area of 2.6 m2/g and mean flow pore size of 7 µm. The preparation of separator didn’t involve orientation procedure and cross-ply delamination as required by previous technique, which greatly simplify the production of fibrous membrane. Chapter 2: In order to develop a battery separator with high tensile strength, PVDF/PC composite tape with fiber in matrix structure was produced by co-extrusion technique. The composition of material, orientation temperature and draw rate, draw ratio and adhesive layer material were investigated to understand their influence on mechanical properties. After oriented under the optimum condition, the tensile strength of PVDF/PC tape are improved around 6 times and Young’s modulus are improved 2 times.
