Polymeric spheres on substrates from a spin-coating process
Abstract.
Formation of polymeric spheres in nanometer to sub-micrometer is achieved through a spin-coating
process with polyamide (from 4,4-(hexafluoroisopropylidene)dianiline and 4,4-dicarboxydiphenylether)
solutions in N,N-dimethylformamide and N,N-dimethylacetamide. The formation of polymeric spheres
and their sizes are dependent on the polymer solution concentrations and the rates in spin-coating. The
polymeric spheres could be obtained on various substrates including silicon, mica, and glass.
