520 $a This thesis presents a systematic investigation to fabricate flexible OLEDs, which exhibit high performance and flexibility, and can be applied in wearable display applications. This research was conducted based on a comprehensive literature review of related technologies. The statement of the existing problems and potential prospects of this technology in wearable smart textile applications put forth the objective of this research.
520 $a Fabrication conditions of Alq3 based FOLEDs were experimentally investigated. Performance of FOLEDs was investigated by varying materials for hole transport and hole injection. Nanocomposite of MWCNTs and PEDOT:PSS was used as the hole injection material of the FOLEDs. Improvement has been obtained by optimizing the FOLED structure of ITO/PEDOT:PSS: w.t. 0.4% MWCNTs/TPD/Alq3/Al. A luminance of 6800cd/m2 was achieved.
520 $a The PEDOT:PSS was further investigated for replacement of ITO by varying doping levels of solvents (DMSO and glycerol) and heating treatments. Three orders of conductivity improvement was achieved and a model was proposed for the conductive improvement mechanism of the solvents treated PEDOT:PSS films.
520 $a Nanocomposites of PEDOT:PSS and SWCNTs together with the DMSO treatment were investigated to develop polymeric anode for FOLEDs. The UV-VIS transmittance and electrical conductivity of the anode were studied as a function of SWCNTs concentration. Within the experimental range, the conductivity of the PEDOT:PSS composite increased with the increase of the SWCNTs concentration, as additional conductive pathway of SWCNTs was created in the PEDOT:PSS system. At the same time, a slight decrease of the transmittance was evident. FOLEDs based on this polymeric anode demonstrated a performance very close to those on ITO anode. This flexible polymeric composite anode exhibits a very good bending property over ITO/PET anode. Only slight resistance increase was found with a bending cycle up to 1000, while the resistance of the ITO/PET anode increases about 100 times of initial resistance with a bending cycles of 20 with the same maximum bending curvature. The polymeric anode is very promising for fully flexible OLEDs or other optoelectronics. Flexible polymeric composite anode with a thickness of 100nm on PET substrate has been made with an optical transmittance of 80% and an electrical resistance of 136.2O/&squ;.
