Templating Ion-Conducting Membranes Using Block Copolymers
TEM
SEO:LiClO4 3:1
SEO (non-doped)
Scale bar : 20 nmRuO4 staining
We have investigated the self-assembly of cylinder-forming PS-b-PEO (SEO) block copolymers doped with various lithium salts. SAXS and TEM confirm that salt doping increases the domain spacing and segregation strength. Additionally, differences in the lithium counterion affect the copolymer morphologies and
induce nanoscale phase transitions.

Here we consider the class of copolymers called \block copolymers" [7] while there are many kinds of copolymers](https://img.pdfslide.us/doc/110x75/5eccfbf97d791301bb64d299/static-and-dynamic-density-functional-theory-and-called-copolymers-here-we.jpg)
