It has been calling attention of both academic and industrial fields and it is already present in some usual devices [1]. Basically, OLEDs have been applied on lighting and displays fields where stability (long lifetime), high efficiency and narrow color-emission are the most essential features of this technology [2-3]. Despite all advantages of OLED technology, there are still some requests that cannot be easily achieved, such as irradiation on large areas and curved surfaces. Therefore, new approaches could lead to breakthrough applications in several materials and device research. In the past years, an increasing utilization of biopolymers is observed in the development of conformable organic OLEDs. Here, in collaboration with different research groups, we produced and characterized four biocompatible polymers to be applied as substrates for OLED. (i) Bacterial cellulose (BC), (ii) carboxymethyl cellulose (CMC)/hyaluronic acid (HA) with Laponite®, (iii) Waterborne polyurethane (WBPU) and (iv) PEBAX® 1657. BC is a biocompatible and non-toxic biopolymer that has been successfully applied as substrate for these devices. It has excellent mechanical properties and industrial scalability, however, BC membranes are semi-transparent that limit their outperformance. An interest strategy to improve BC features is the production of a polymeric composite of carboxymethyl cellulose (CMC)/hyaluronic acid (HA) already explored in literature [4] adding laponite, that gives some mechanical strength, improving the rigidity and remaining flexibility of the film. On the other hand, WBPUs are nontoxic and nonflammable materials. They present similar characteristics of polyurethanes prepared by using organic solvents, but their syntheses are much more environmentally friendly [5]. Castor oil based WBPU were prepared via casting. Finally, PEBAX® 1657 is a well-known as the trademark polymeric composite from ether block amide[6], which is a thermoplastic elastomer consisting of linear chains and two segments (hard and soft segments) and were produced via casting. In this work, these advanced substrates were used to fabricate OLEDs. For all the four substrates, 200nm of SiO2 onto 150nm of Indium Tin Oxide (ITO) were deposited via rf-magnetron sputtering as cathode for the OLEDs produced. Preliminary results indicate the best tradeoff efficiency/stability for WBPU and PEBAX substrates. References: 1 Tang, C. W.; VanSlyke, S. A. Appl. Phys.
