At the same time i also did many primary experments on separator and these polymer membrane can be used in as soft packaging li - ion battery ’ s separator. used polyvinylidene fluoride ( pvdf ) as the basic material, added cotton fibre and starch in, cooked with 100 in boiling water afer 3 hours, the starch inflate, and then acquire porous polymer membrane. in the process of coating polyester film, copper foil and aluminum boil were used to as carrier,
選用的基體材料為pvdf ，同時向其中添加棉纖維和澱粉，最後利用100沸水對隔膜進行3小時蒸煮處理使澱粉溶脹，從而達到造孔的目的。在塗布工藝的篩選中，通過對麥臘片、銅箔、鋁箔進行篩選，最後選定以銅箔為載體來進行塗布處理。當以銅箔為載體時，可以使隔膜正反兩面物理性質達到基本一致。 -
