dc.description.abstract使用功能性高分子薄膜作為顯示器已經成為新的研究方向。顯示器的性能不只能從機械結構進行改善,近年來更有透過「材料自組織行為」直接改變微結構以影響整體產品特性的目的,像是加入微小顆粒到高分子溶液系統中便可提升耐熱性、導電性等材料性質,但含有微粒的高分子塗佈液製程研究仍尚未明朗。 本研究目的是要探討當無機粒子以一定比例加入高分子材料後粒子團聚及分散等運動行為,並探討附著在基板上的官能基吸引力對奈米顆粒沉聚行為的影響。同時也嘗試建立無機粒子混成塗佈液的成成膜前後之膜厚關係。 研究中使用刮刀塗佈棒將不同配方的混成塗佈液均勻分布在基板上,搭配高溫烘箱使塗佈後濕膜硬化,並分別以膜厚儀及顯微鏡觀察塗膜厚度及成膜後奈米顆粒的團聚、分散情形,隨後以影像擷取的方式量化之。 研究結果顯示,基板上的親水性官能基確實會對混成塗佈液內的奈米顆粒產生吸引力,並造成沉聚現象,而基板附著力的改變所造成的速度滑移也改變了流體剪切率,不只明顯觀察到奈米顆粒受官能基吸引後的變化趨勢,同時也可透過實驗而得的關係式預估混成塗佈液後的乾膜厚度,本研究結果可供未來探討奈米混成高分子塗佈液功能性機制時之參考。zh_TW
dc.description.abstractRecently, using functional polymer thin film has become a new trend of technical development. The performance of a display can be improved not only from its mechanical structure but from its raw material. The “Self-Assembly” behavior can change the material properties, such as thermal endurance and conductivity, when nanoparticle-hybrid polymer solution is made. However, the studies on the procedure of nanoparticle-hybrid polymer solution is yet been done. This study investigated the dispersion and aggregation behavior of inorganic nanoparticle is hybrid with polymer solution with designated hybrid ratio. The attraction for nanoparticle caused by the hydrophilic functional group, which is adhered on the substrate, is also investigated. In addition, the relation of nanoparticle-hybrid polymer thin film between solidified-film and yet-solidified film is founded simultaneously. The hybrid polymer solution with different recipes is coated uniformly on the substrate by the coating rod and the films are solidified by the oven. Film thickness detection and nanoparticle distribution are detected by the thickness gauge and SEM (Scanning Electron Microscope) respectively. The distribution data will be quantified by an image collection software. The result shows that the hydrophilic functional group does have influence on attracting nanoparticles and causes aggregation phenomena, the variation of adhesion force on the substrate results in the slip of velocity and changes the shear rate of the hybrid polymer solution. Overall, the tendency of variation caused by functional group attractive fore can be observed, and the thickness model of polymer thin film can be determined by an experimental equation. The results of this study offers references for further research of the functional mechanisms of nanoparticle-hybrid polymer thin film procedure.en_US
