Potential applicationsPolyferrocenes currently have no commercial applications, despite being the subject of research for nearly 50 years. Polyvinylferrocene gives electroactive films that have been investigated as glucose sensors.[2] CoatingsSatellites charge themselves by the bombardment with charged particles of the solar wind. Charging can lead to an arc discharge which can impair the function of the satellite due to magnetic disturbances and material failure. To avoid these impairments, coatings of electrically weak or non-conductive plastic components of thin films of poly(1,1'-ferrocen-silane) were examined. These carry off the charge generated by the irradiation and thus could protect the satellite from overloads.[3]Polymers with high refractive indexPolyferroccenes have attracted interest as high-refractive-index polymers, such as in antireflection coatings or for light-emitting diodes.[4]Poly(1,1'-ferrocene-silane)e, poly(1,1'-ferrocene-phosphane) and polyferrocenes with phenyl side chains are polymers with unusually high refractive index, with values in the refractive index of up to 1.74. These polyferrocenes show good film-forming ability.[5] Plasma-assisted reactive ion etchingPoly(ferrocene-dimethylsilane)s (PFS) are promising as barrier materials in plasma-assisted reactive ion etching. Due to the presence of iron and silicon in the main chain, the polymer proved to be relatively stable compared to purely organic polymers. During the etching, a thin iron and silicon-containing oxide layer was formed on the surface of the poly(ferrocene-dimethylsilane).[6] Further reading
