AB  - Mixed micelles formed by co-assembly of pairs of block copolymers (BCPs) can 
      develop novel morphologies and generate useful properties not accessible from 
      homomicelles. For micelles consisting of two different polymers in the corona, 
      identifying the location of the corona chains is a critical part of morphology 
      characterization. Coronal segregation in mixed micelle is often characterized by 
      transmission electron microscopy in combination with selective staining of 
      individual polymers. In this study, Karstedt's catalyst is used for selective 
      Pt(0)-olefin coordination staining of polyisoprene (PI) and 
      poly(methylvinylsiloxane) (PMVS) corona chains in the presence of 
      poly(dimethylsiloxane) (PDMS) corona chains in cylindrical mixed micelles with a 
      crystalline poly(ferrocenyldimethylsilane) (PFS) core. Previous experiments using 
      OsO(4) as a stain did not enable visualization of nanoscale coronal segregation 
      in mixed micelles obtained from co-assembly of PFS-b-PI and PFS-b-PDMS, as well 
      as PFS-b-PMVS and PFS-b-PDMS.
