| Summary: | 碩士 === 國立中興大學 === 材料工程學研究所 === 93 === Polymer substrate has considered to be used in the flat panel display, where the demand for remote information access is driving the development of rugged, flexible, lightweight, power efficient displays. However, there are some technological difficulties for the realization of a display on polymer substrate, such as lower thermal stability and higher oxygen and water molecules permeation.
Polyethersulfone（PES） is an amorphous polymer containing excellent thermostability and transparency, high glass transition temperature, lower birefringence and outstanding chemical resistance which is considered to be a candidate for polymer substrate used in the flat panel display. In this research we have successfully been prepared PES/clay nanocomposites through the mixing of PES with organically-modified clay in solution to reduce the water/oxygen permeation. The addition of clay into PES increase the physical and mechanical properties of PES, and the water and oxygen permeation can be reduced by 29% and 24%. Further surface treatment by plasma and multi-layer organic/inorganic barrier layer has also been developed.
The inorganic material SiO2 prepared by sol-gel process with various diameters, such as 30 nm, 40 nm and 45 nm, can be coated on the surface of PES/clay nanocomposites. The water and oxygen permeation of nanocomposites can further reduce by 29% and 49%.
