背景技术Background technique
现有技术中,触控电极与传输线交会处的接触区中,传输线材料多为整片实心金属层,触控电极使用有机材料粘着于传输线上。因此,接触面积越大、接触的阻值越小。然而,有机材料对金属等无机材料无法形成键结,造成附着力不佳进而使触控电极脱落。有鉴于此,现有技术实有待改善的必要。In the prior art, in the contact area where the touch electrode and the transmission line meet, the material of the transmission line is mostly a solid metal layer, and the touch electrode is adhered to the transmission line by using an organic material. Therefore, the larger the contact area, the smaller the resistance of the contact. However, organic materials cannot form bonds with inorganic materials such as metals, resulting in poor adhesion and thus the touch electrodes falling off. In view of this, the existing technology needs to be improved.

Examples of suitable additives and binders include, but are not limited to, carboxymethyl cellulose (CMC), 2-hydroxyethyl cellulose (HEC), hydroxypropyl methyl cellulose (HPMC), methyl cellulose ( MC), polyvinyl alcohol (PVA), tripropylene glycol (TPG), and xanthan gum (XG); and surfactants such as ethoxylates, alkoxylates, ethylene oxide and propylene oxide and their Copolymers, sulfonates, sulfates, disulfonates, sulfosuccinates, phosphates, and fluorosurfactants (eg, DuPont's ).
在一些实施例中,纳米线分散液或“墨水”包含以重量计0.0025%至0.1%的表面活性剂(例如,FSO-100的较佳范围是0.0025%至0.05%)、0.02%至4%的粘度改质剂(例如,HPMC的较佳范围是0.02%至0.5%)、94.5%至99.0%的溶剂及0.05%至1.4%的金属纳米线。适宜表面活性剂的代表性实例包含FSN、FSO、FSH、Triton(x100、x114、x45)、Dynol(604、607)、正十二烷基b-D-麦芽糖苷及Novek。适宜粘度改质剂的实例包含羟丙基甲基纤维素(HPMC)、甲基纤维素、黄原胶、聚乙烯醇、羧甲基纤维素及羟乙基纤维素。适宜溶剂的实例包含水及异丙醇。In some embodiments, the nanowire dispersion or "ink" comprises 0.0025% to 0.1% by weight of a surfactant (eg, The preferred range for FSO-100 is 0.0025% to 0.05%), 0.02% to 4% viscosity modifier (eg, the preferred range for HPMC is 0.02% to 0.5%), 94.5% to 99.0% solvent and 0.05% % to 1.4% metal nanowires. Representative examples of suitable surfactants include FSN, FSO, FSH, Triton (x100, x114, x45), Dynol (604, 607), n-dodecyl bD-maltoside and Novek. Examples of suitable viscosity modifiers include hydroxypropyl methylcellulose (HPMC), methylcellulose, xanthan gum, polyvinyl alcohol, carboxymethylcellulose, and hydroxyethylcellulose. Examples of suitable solvents include water and isopropanol.
分散液中的纳米线浓度可影响或决定纳米线网络层的参数,例如厚度、导电率(包括表面导电率)、光学透明度及机械特性。可调节溶剂百分比以提供纳米线在分散液中的期望浓度。然而,在较佳实施例中,其他成份的相对比率可保持不变。具体而言,表面活性剂对粘度改质剂的比率较佳介于约80至约0.01范围内;粘度改质剂对金属纳米线的比率较佳介于约5至约0.000625范围内;且金属纳米线对表面活性剂的比率较佳介于约560至约5范围内。分散液中各组份的比率可端视所使用基板及施加方法而改变。用于纳米线分散液的较佳粘度范围介于约1cP与100cP之间。The nanowire concentration in the dispersion can affect or determine the parameters of the nanowire network layer, such as thickness, electrical conductivity (including surface electrical conductivity), optical transparency, and mechanical properties. The solvent percentage can be adjusted to provide the desired concentration of nanowires in the dispersion.

Specifically, the ratio of surfactant to viscosity modifier is preferably in the range of about 80 to about 0.01; the ratio of viscosity modifier to metal nanowire is preferably in the range of about 5 to about 0.000625; and the metal nanowire The ratio to surfactant is preferably in the range of about 560 to about 5.

The preferred viscosity range for nanowire dispersions is between about 1 cP and 100 cP.
在涂覆后,通过蒸发移除挥发性液体。可通过加热(例如烘焙)来加速蒸发。所得纳米线网络层可需要后处理以使其导电。如下文所阐述,此后处理可是涉及暴露于热、电浆、电晕放电、UV-臭氧或压力下的制程步骤。After coating, the volatile liquid is removed by evaporation. Evaporation can be accelerated by heating (eg baking). The resulting nanowire network layer may require post-processing to make it conductive. As set forth below, post-processing may be process steps involving exposure to heat, plasma, corona discharge, UV-ozone, or pressure.

"Light transmittance" (or "light transmittance") refers to the percentage of incident light transmitted through a medium. In various embodiments, the light transmittance of the conductive layer is at least 80% and can be as high as 98%. Performance enhancing layers such as adhesion layers, anti-reflection layers or anti-glare layers can further help reduce the overall light transmittance of the transparent conductor. In various embodiments, the transmittance (T%) of the transparent conductor may be at least 50%, at least 60%, at least 70%, or at least 80%, and may be as high as at least 91% to 92% or at least 95%.
