Abstract: | 本研究利用新興材料氧化鋁矽奈米管(AlSiNT)與商用奈米銀線(AgNW)混合,並使用超音波噴塗技術於PET基材上製作透明導電薄膜(AgNW + AlSiNT薄膜)。這種新型混合薄膜成功突破AgNW薄膜在導電度提升時,穿透度會隨之下降的限制。我們探討AgNW與AlSiNT的混合濃度改變以及噴塗溶液的使用量對於導電度與穿透度的影響。本研究中AgNW + AlSiNT薄膜最佳效能表現為片電阻10 Ω/sq、穿透度94.2%,相較相同導電度表現的AgNW薄膜(片電阻10 Ω/sq、穿透度86.7%),此薄膜減少了33%的成本。我們利用SEM與EDS多點分析技術比較AgNW + AlSiNT薄膜與AgNW薄膜的差異,發現AlSiNT能夠幫助AgNW在成膜時分散更均勻,且在AgNW + AlSiNT薄膜中發現奈米銀顆粒(AgNP)的產生,使得AgNW+AlSiNT薄膜的導電度與穿透度表現都比較優異。我們認為將AlSiNT加入AgNW中,不僅能降低成本,同時也可以有效提升透明導電薄膜的導電度與穿透度效能。 In this work we mixed emerging aluminosilicate nanotube (AlSiNT) with the commercial silver nanowires solution (AgNW), and then cast this mixture on the flexible PET substrate by ultrasonic nozzle spray deposition (AgNW + AlSiNT film). The novel hybrid films transcend the performance upper bound of the commercially available silver nanowires. We investigated how the concentration of AgNW and AlSiNT and the amount of spray solution affect the conductivity and transparency of the film. In our hybrid system, the best performance of AgNW + AlSiNT film is 10 Ω/sq at 94.2% transmittance. Compared to the AgNW film with similar conductivity (10 Ω/sq at 86.7% transmittance), the film prepared in this work reduces 33% of the cost. We used SEM and EDS multi-point analysis techniques to investigate the difference between AgNW + AlSiNT film and AgNW film. It showed that AlSiNT helps AgNW to disperse uniformly during film formation, and silver nanoparticles were found in AgNW + AlSiNT film to make the performance better in conductivity and transparency. From our perspective, the addition of AlSiNT to AgNW does not only reduces the cost, but also effectively improves the conductivity and transparency of the transparent conductive film. |
