| Summary: | 博士 === 元智大學 === 光電工程學系 === 101 === In this thesis, various ultraviolet (UV) curable polymeric nanocomposites has been
prepared by conventional heating method, fast UV illumination as well as rapid
microwave irradiation and applied for the encapsulation of optoelectronic devices,
brightness enhancement films (BEFs) of OLEDs, and light trapping (LT) films of
OSCs. In case of lab-made UV curable polymeric nanocomposites, silicone-PUacrylate/
silica and silicone-PU-acrylate-epoxy/silica nanocomposites exhibit better
physical properties than other ones. Under UV irradiation, BEFs have also been
successfully manufactured by imprint technique and applied for OLEDs. With BEFs
exhibit better electroluminescent performances than those without BEFs. In case
of green OLEDs, the luminance and electroluminescent yield with BEFs are respectively
larger than those without BEFs. In case of white OLEDs, moreover, the
luminance and electroluminescent yield with BEFs are respectively larger than those
without BEFs. Under UV irradiation, LT films have also been successfully manufactured
by imprint technique and applied for OSCs. The experimental results reveal
that the hazes of devices with inverted pyramid and v-shaped LT films with higher
hazes exhibit superior photoelectric conversion properties. The effects of antioxidants
and processing parameters on the thermal stability and processability of sPS
have been also investigated. Furthermore, feasible estimation of sPS/PPO alloys for
reflective cups of light emitting diodes (LEDs) have also been made, demonstrating
that sPS/PPO alloys are potential candidates by the appropriate prescription of
impact modifiers, flame retardants, and titanium dioxide.
