Abstract

Microporous films with various kinds of geometrical patterns including ellipsoids and rectangles are fabricated by using a self-organization process and shrinking. A shrinkable substrate can be used to change the shapes and sizes of honeycomb pores. The pit size can be miniaturized from several micrometers to hundreds of nanometers by repeating the shrinkage.
