Controlled poly(pyrrole) patterning by microcontact printing on glass and poly(ethylene terephthalate) substrates

Abstract : In this work, we present an easy and low-cost technique for the fabrication of poly(pyrrole) (PPy) micro structures onto glass and poly(ethylene naphthalate) (PET) substrates by combining microcontact printing (mu CP) and electroless polymerization. The substrates: glass and PET were activated in piranha and potassium hydroxide (KOH) solution, respectively. The activated substrates were then functionalized with 11-(triethoxysilyl)undecanal (TESUD) using structured polydimethylsiloxane (PDMS) stamps and transferred by mu CP. After printing, the PPy was grown onto the silane patterned surface using electroless polymerization. The printed patterns were characterized by optical microscopy, scanning electron microscopy (SEM), and atomic force microscopy (AFM). The results have shown that PPy rings can be developed and were well-defined onto glass and PET substrates through mu CP and electroless polymerization. The PPy was grown to dimensions of an inner ring diameter (IRD) of 50, 30 and 20 mu m and an outer ring diameter CORD) of 30, 20 and 10 mu m, respectively. The estimated thickness of PPy structures was measured at 2.8 +/- 0.4 mu m by AFM. This innovating technique represents a first step in the production of a PPy printed matrix for potential flexible biosensors.
