Abstract: A single-walled carbon nanotube composition includes single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes in association with a polymer having one or more oligoether side groups. The oligoether side groups render the composition dispersable in polar organic solvents, for example alkyl carbitols, permitting formulation of ink compositions containing single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes. Such ink compositions may be readily printed using common printing methods, such as inkjet, flexography and gravure printing.

Abstract: A copper-based ink contains copper hydroxide and diethanolamine. The ink may be coated on a substrate and decomposed on the substrate to form a conductive copper coating on the substrate. The ink is low cost and micron-thick traces of the ink may be screen printed and thermally sintered in the presence of up to about 500 ppm of oxygen or photo-sintered in air to produce highly conductive copper features. Sintered copper traces produced from the ink have improved air stability compared to traces produced from other copper inks. Sintered copper traces having sheet resistivity of about 20 mΩ/□/mil or less may be obtained for 5-20 mil wide screen-printed lines with excellent resolution.

Abstract: A thin film transistor (TFT) has a gate electrode; a gate insulation layer, a semiconducting channel separated from the gate electrode by the gate insulation layer; a source electrode and a drain electrode. The gate insulation layer is a cross-linked cyanoethylated polyhydroxy polymer, e.g. a cross-linked cyanoethylated pullulan, having a high dielectric constant and the semiconducting channel has a network of semiconducting carbon nanotubes. The semiconducting channel is adhered to the gate insulation layer through a polymeric material. The carbon nanotubes adhere to the polymeric material and the polymeric material reacts or interacts with the gate insulation layer. TFTs have high mobilities while maintaining good on/off ratios.

Abstract: The present invention relates to an electronic device comprising a printed substrate comprising a trace of molecular ink thereon, the molecular ink being sintered to form a conductive metal trace forming the electronic device, wherein the molecular ink is chosen from a) a flake-less printable composition of 30-60 wt % of a C8-C12 silver carboxylate, 0.1-10 wt % of a polymeric binder and balance of at least one organic solvent, all weights based on total weight of the composition; or b) a flake-less printable composition of 5-75 wt % of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate, 0.25-10 wt % of a polymeric binder and balance of at least one organic solvent, all weights based on total weight of the composition.

Abstract: A two-step sc-SWCNT enrichment process involves a first step based on selective dispersion and extraction of semi-conducting SWCNT using conjugated polymer followed by a second step based on an adsorptive process in which the product of the first step is exposed to an inorganic absorptive medium to selectively bind predominantly metallic SWCNTs such that what remains dispersed in solution is further enriched in semiconducting SWCNTs. The process is easily scalable for large-diameter semi-conducting single-walled carbon nanotube (sc-SWCNT) enrichment with average diameters in a range, for example, of about 0.6 to 2.2 nm. The first step produces an enriched sc-SWCNT dispersion with a moderated sc-purity (98%) at a high yield, or a high purity (99% and up) at a low yield. The second step can not only enhance the purity of the polymer enriched sc-SWCNTs with a moderate purity, but also further promote the highly purified sample to an ultra-pure level. Therefore, this two-step hybrid process provides sc-SWCNT materials with a super high purity, as well as both a high sc-purity (for example greater than 99%) and a high yield (up to about 20% or higher).

Abstract translation: 两步sc-SWCNT富集方法包括基于使用共轭聚合物选择性分散和提取半导体SWCNT的第一步骤，然后基于吸附方法的第二步骤，其中第一步骤的产物暴露于无机 吸收介质以选择性地结合主要金属SWCNT，使得在溶液中分散的物质进一步富集在半导体SWCNT中。 该方法可以容易地扩展到大直径半导体单壁碳纳米管（sc-SWCNT）富集，其平均直径在例如约0.6至2.2nm的范围内。 第一步以高产率或高纯度（99％及以上）以低产率产生具有缓和sc-纯度（98％）的富集的sc-SWCNT分散体。 第二步不仅可以提高中等纯度的富集聚合物的sc-SWCNT的纯度，还可以进一步促进高纯度样品达到超纯水平。 因此，这种两步混合工艺提供具有超高纯度的sc-SWCNT材料，以及高sc纯度（例如大于99％）和高产率（高达约20％或更高）两者。

Abstract: A flake-less molecular ink suitable for printing (e.g. screen printing) conductive traces on a substrate has 30-60 wt % of a C8-C12 silver carboxylate or 5-75 wt % of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate, 0.1-10 wt % of a polymeric binder (e.g. ethyl cellulose) and balance of at least one organic solvent. Conductive traces formed with the molecular ink are thinner, have lower resistivity, have greater adhesion to a substrate than metal flake inks, have better print resolution and are up to 8 times less rough than metal flake inks. In addition, the shear force required to remove light emitting diodes bonded to the traces using Loctite 3880 is at least 1.3 times stronger than for commercially available flake-based inks.
