Polymeric spheres on substrates from a spin-coating process

Formation of polymeric spheres in nanometer to sub-micrometer is achieved through a spin-coating process with polyamide (from 4,4′4,4′-(hexafluoroisopropylidene)dianiline and 4,4′4,4′-dicarboxydiphenylether) solutions in N,NN,N-dimethylformamide and N,NN,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.
