Abstract	Accepted on January 21, 2010. Temperature and initial concentration gradients have been used independently during thermal-induced phase separation to create anisotropic functional porous polymeric materials. In this paper, we developed and implemented a mathematical model that combines both linear temperature and initial linear concentration gradients during the thermal-induced phase separation process. The numerical results show that the ensuing anisotropic morphology depends largely on the directions of both the temperature and concentration gradients. This allows for a better understanding and control of the fabrication process of porous functional polymeric materials. The numerical results are explained using existing spinodal decomposition theory.
