Multifunctional polymeric patterning surfaces are of
significant importance for numerous surface-based researches. We demonstrated
that commerical polymer of polyethylenimine (PEI) with rich amino groupscan be used as a
versatile ink for the direct fabrication of PEI patterning surfaces viasupramolecular
interaction between amino in PEI and -OH on silicon wafer induced
by microcontact
printing (μCP). The thickness and shapes of the formed PEI surfaces can be
finely tuned by changing the molecular weight and/or concentration of
PEI. The obtained polymeric patterning surfaces could be amplified further to grow other polymersas brushes, or be explored as novel
surface-enhanced Raman scattering (SERS) active material by electrostatic
adsorption with negative charged gold nanoparticles
(AuNPs).
