Nanostructured crosslinkable micropatterns by amphiphilic dendrimer stamping

摘要

Microcontact printing was used to deposit stable, nanostructured, amphiphilic and crosslinkable patterns of poly(amidoamine organosilicon) (PAMAMOS)-dimethoxy-methylsilyl (DMOMS) dendrimer multilayers onto silicon wafers, glass, and polyelectrolyte multilayers. The effects of dendrimer ink concentration, contact time, and inking method, on the thickness, uniformity, and stability of the resulting patterns were studied using optical microscopy, fluorescence microscopy, atomic force microscopy (AFM), and contact-angle analysis. Microarrayed dendrimer film thickness was found to be controllable by conditions used during spin self-assembly.
