PLZT (9/65/35) membranes composed of micro fibers were developed by electrospinning using a suspension of PLZT/PVC. The electrospun fibrous membrane of ceramic/PVC composite was heat treated at 800 degrees C, 900 degrees C and 1000 degrees C for 1 hr in air to remove organic components and PVC. The effect on the morphology and composition of the membranes of PLZT/PVC, due to the calcination temperature and the variation in the proportion by weight (ratios 1:19, 1:9 and 3:7) of the solution used in electrospinning, were examined by SEM and ZAF. Typical fibers diameter were obtained between 16 mm and 25 mm with a length of fibers over 500 mm. Nanoporous were also formed into the microfibers fibers with diameters between 350 nm and 1000 nm.
