AbstractThermoplastic semi-crystalline polymers such as polyethylene terephthalate and polyethylene naphthalate (PEN) are very promising substrate materials for flexible organic electronic devices (FEDs), such as flexible displays and lighting (OLEDs) or flexible photovoltaic cells (OPVs). They have many advantages such as good clarity, reasonable coefficients of thermal expansion, chemical resistance, moisture absorption and price, while their upper operating temperatures and surface roughnesses are not so good. The performance, efficiency and lifetime of FEDs are greatly affected by the optical, electrical and structural properties, that is surface quality (roughness and cleanliness) of the polymer substrates used (Choi et al., 2008; Logothetidis, 2008). Therefore, study of the surface modification of these flexible polymer substrates and their surface nanotopography are of considerable significance. Several surface modification methods can be used to modify the polymer surfaces, such as chemical, thermal, electrical and plasma treatments (Laskarakis et al., 2008; Fávaro et al., 2007; Velev et al., 2013; Navaneetha Pandiyaraj et al., 2009). In the work reported in this paper, PEN film surfaces were modified by argon glow discharge and chemical treatment. The changes in surface roughness and surface tension of treated samples were determined using atomic force microscopy (AFM) and contact angle measurements. Treated samples were used as a substrate for inkjet printing quality tests, using a grapheme-based hetero-phase ink. This is a very useful technique for rapid prototyping of electronic devices. It is also low cost because it does not need additional tools for printing different patterns (Jabłoński et al., 2011).
