透明導電膜應用很廣,液晶顯示器、太陽能電池、觸控面板、發光二極體等光電產品都需要使用到,現今最常使用的透明導電物質為銦錫氧化物(ITO),但因ITO具陶瓷脆且不易彎曲的特性而且銦原料短缺,在未來勢必將用其他物質取代。
本研究第一部分使用化學法合成銀的奈米線,調整不同聚乙烯吡咯烷酮與銀的前驅物硝酸銀的比例、不同的還原溫度和不同還原溶劑,找到適合當透明導電膜銀奈米線的長寬比,並使用塗佈棒塗佈於軟性聚對苯二甲酸乙二醇酯基板上製備透明導電膜,再藉由加熱處理,以降低片電阻,製作出穿透度86.5%,片電阻150 Ω/square的導電薄膜。第二部分利用微乳液製作自組裝網狀導電薄膜,將水、甲苯、氯苯、界面活性劑與奈米導電材料混合製作出微乳液,塗佈於疏水處理的玻璃基板上形成自組裝網狀導電膜,可成功製造出網狀圖形,搭配不同的導電物質可製作出不同導電程度之薄膜。
Transparent conductive film is a material with wide applications, such as liquid crystal displays (LCD), solar cells, touch panels, light emitting diodes, etc. The most commonly used transparent conductive material today is indium tin oxide, however, it will soon be replaced by other materials due to its non-flexible ceramic nature and scarcity of supply.
In this study, we use soft solution process to fabricate silver nanowire by adjusting the molar ratio of PVP and AgNO3, growth temperature, and solvent to find the optimal growth parameter for the ratio of length and diameter. Then, we coat silver nanowire solution on PET substrate to fabricate the transparent conductive films with heating to reduce sheet resistance on transparent conductive films. Silver nanowire transparent conductive films of 86.5% optial transmittance and 150 Ω/square were obtained.
The second part focuses on fabricating nano conducting materials by microemulsion of water, toluene, chlorobenzene, and surfactant, followed by coating on hydrophobic glass substrate to form self-assembling conductive thin film. Mesh patterns were successfully fabricated, and films with different conductivities can be made from various conductive materials.
