| 摘要: | 導電銀漿料在智慧紡織品的實際應用上已被大量的關注，但也出現一些挑戰，主要是因為織物具有表面起伏及多樣化的組織結構。此外，當織物在使用過程中會受到穿脫和運動等外力的影響，影響銀漿在紡織品上的拉伸導電性能。本研究為改善這樣的情形，採用多元醇合成方式成功製備奈米銀線，並選擇不同粒徑的銀顆粒製備銀漿料，將不同奈米銀線比例添加至銀漿料中，利用網版印刷技術將不同配方的銀漿料塗布至彈性針織布上，進行SEM、FTIR等分析。同時，評估奈米銀線對於織物伸展後的導電性，拉伸織物至不同長度進行電阻值測試。結果顯示，添加2wt%奈米銀線的銀漿料塗布在織物上，當織物拉伸長度至60%，其織物表面電阻值仍可維持在100Ω/dm以下，顯示將奈米銀線添加到銀漿中，可有效提升銀漿料的可拉伸性，以符合智慧紡織品所需的穩定性。
Considerable attention has been garnered by the practical application of conductive silver paste in smart textiles, but it is also acknowledged that challenges are presented, primarily attributed to the surface roughness and diverse structural organization of textiles. Moreover, the stretchable conductivity of silver paste on textiles can be affected by external forces such as wearing and movement during usage. To address this issue, a polyol synthesis method was employed in this study to successfully prepare silver nanowires, and silver particles of different sizes were selected to prepare silver paste. Various proportions of nano silver wires were added to the silver paste, which was subsequently applied to elastic knitted fabric using screen printing technology. SEM, FTIR, and other analyses were conducted. Simultaneously, the conductivity of the textiles after stretching was evaluated by conducting resistance tests on textiles stretched to different lengths. The results indicate that when 2wt% of nano silver wires are added to the silver paste and applied to textiles, the surface resistance of the fabric can still be maintained below 100Ω/dm when the fabric is stretched to 60%. It is indicated that the stretchability of the silver paste can be effectively enhanced to meet the stability requirements of smart textiles by adding silver nanowires to the silver paste. |
