OS1332-302 Development of Simulation Technology for Production of Porous Polymeric Membranes

Abstract

Porous Polymeric Membranes are used for ion exchange membranes, membrane filter and separators of batteries due to its micro-porous structure. Extension method is one of the inexpensive processes. However, any suitable stability condition of the process has not yet been proposed. In this paper, SEM observations of production process are carried out and the simulation technology for production is developed for improvement in productivity. In the simulation model, the evolution equation of microscopic damage, constitutive equation depending on microscopic damage and the homogenization method are used for representation of evolution of micro-porous structure of crystalline polymer. It is indicated that numerical results obtained here agree with the SEM observations well.
