Characterization of nanostructure and cell compatibility of polyaniline films with different dopant acids

Article Abstract:

Polyaniline (PANi) films are prepared by direct polymerizing deposition with different kinds of acids as dopants and they are characterized by using atomic force microscopy. The results have shown that the PANi films are used to culture neurotic cells and that their surface architecture on the nanoscale has affected the cell function such as attachment and proliferation.

Physical insights into the photoactivated Ullmann coupling process producing highly conjugated oligothiophene films on a copper substrate

Article Abstract:

The details of surface reactions producing > 100-nm-thick conjugated polymer films are described. The key for the successful growth > 100-nm-thick films of the highly conjugated oligothiophene through surface-mediated Ullmann coupling reactions in the continuous regeneration of the active copper sites in the deposited monomer film.
