Spontaneous Vertical Ordering and Pyrolytic Formation of Nanoscopic Ceramic Patterns from Poly(styrene‐b‐ferrocenylsilane)

Abstract
The rapid generation of nanopatterned surfaces using thin films of the amorphous diblock copolymer poly(styrene‐b‐ferrocenylethylmethylsilane) (PS‐b‐PFS) is reported. Spontaneous self‐assembly into vertically oriented cylinders of PFS in a PS matrix is observed on a variety of substrates by spin or dip coating, irrespective of the substrate surface polarity. Pyrolysis of the films affords arrays of 20 nm Fe‐containing ceramic nanoparticles, (see Figure, AFM, 4 μm2 scan area).
