二元溶剂掺杂的PEDOT/PSS在纸上的导电性研究
|
摘要
目的提高纸张基底上有机材料的导电性。方法以有机半导体材料聚3,4-乙撑二氧噻吩/聚苯乙烯磺酸盐(PEDOT/PSS)为导电材料,以不同纸张(硫酸纸、胶版纸、复印纸和喷墨打印纸)做基底,利用二甲基亚砜(DMSO)、异丙醇(IPA)二元溶剂掺杂PEDOT/PSS溶液,对比分析PEDOT/PSS涂层在纸张上的导电性能,同时探讨多层单一浓度、多层降浓度、多层升浓度涂布对涂层导电性能的影响。结果在PEDOT/PSS溶液中掺杂单一溶剂DMSO,添加DMSO体积分数为5%时,可以得到最佳的导电性能;通过二元溶剂掺杂优化PEDOT/PSS溶液在纸上的成膜,最佳体积分数为23%;同时在不同浓度配方下,喷墨打印纸的涂层导电性能最好;多层降浓度涂布可以将涂层方阻由13 kΩ/降为0.255 kΩ/。结论利用二元溶剂掺杂能够在很大程度上提高了PEDOT/PSS导电涂层的导电性能;表面致密、平滑及透气性低的纸张是最佳的基底选择;多层降浓度涂布是最佳方式。
The paper aims to improve the conductivity of the organic material on the paper substrate. With organic semiconductor material Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate(PEDOT/PSS) as conductive materials,different papers(glassine paper, offset paper, copy paper, and inkjet paper) were used as the substrate, PEDOT/PSS solution was doped with dimethyl sulfoxide(DMSO) and isopropanol(IPA) binary solvent. The conductivity of PEDOT/PSS coating on paper was compared and analyzed. At the same time, the effects of single concentration coating, falling concentration coating and rising concentration coating on the conductivity of the coating were discussed. When doping a single solvent DMSO in PEDOT/PSS solution, the best conductivity can be achieved by adding 5% DMSO. The PEDOT/PSS solution was optimized on the paper by doping binary solvent. The optimal volume fraction was 23%. At the same time,the coating of inkjet paper had the best conductivity under different concentration formulas. Multi-layer coating of falling concentrations could reduce the coating resistance from 13 kΩ/□ to 0.255 kΩ/□. Doping with binary solvent can greatly improve the electrical conductivity of PEDOT/PSS conductive coating. Paper of dense surface, good smoothness and low permeability is the best choice of substrate. The best way is a multilayer falling concentration coating.
