Scanning electron micrograph of surface

The processes for manufacturing microporous membranes can be broadly divided into wet processes and dry processes. Both processes usually employ one or more orientation steps to impart porosity and/or increase tensile strength. Figure 2 shows scanning electron micrographs of surfaces of separators made by each process.

The changes in topographical features, induced by catalytic gasification, are quite different from those changes induced in pure carbons. These changes are best described by examination of scanning electron micrographs of surfaces of oxidized carbons.
