The Effect of Infusing Tio2 Nanoparticles on the Optoelectronic Properties of Mehppv Thin Films for Oled Fabrication.

The use of MEHPPV in OLED application has increased currently. The main issue surrounds its ability to perform well optically and electronically. To enhance the performance of MEHPPV polymer in this sense, this study looks at infusing TiO2 nanoparticles at different percentages from 0.1g TiO2 in MEHPPV polymer to 0.5g TiO2 in MEHPPV polymer in increasing ranges of 0.1g and examining the performance. Several techniques such as UV-Vis, SEM, and XRD were used. The future looks at the possible use of the four-point probes and nanoindentation in checking the performance in addition to the techniques used to establish a greater information base. The solution of the combination of these two chemicals will be spin-coated onto two types of glasses to form a thin film for examination using the mentioned techniques above. This will be done while varying the composition of TiO2 up to an optimum level, that improves performance but does not compromise mechanical properties.
