NanoIntegris Launches higher-performing Ultra High-Purity Single-Walled Nanotubes: IsoSol-S100 TM Raymor-NanoIntegris breaks a new barrier by becoming the world's first company to commercialize ultra high-purity, polymer-wrapped, semiconducting carbon nanotubes dispersed in organic solvents: IsoSol-S100 TM. This innovative product, offered in powder or solution form, is the first semiconducting single-walled carbon nanotube material on the market with purities exceeding 99.9%. IsoSol-S100 has the following properties: - Can be readily dispersed in a variety of organic solvents such as toluene and xylenes. - Polymer/nanotube ratio can be adjusted to less than a factor of four with nanotube concentrations 10X higher than our aqueous dispersions. - Displays a 50% greater shelf life, as compared to aqueous surfactant solutions. - Allows the production of printed transistors with current ON/OFF ratios on the order to 1.8×10 6 and mobilities on the order of 30 cm 2/(Vs) - Is perfectly-suited for commercial ink jet and aerosol jet printing. IsoSol-100 is based on an RF-plasma grown carbon nanotube source material supplied by Raymor Nanotech at industrial scale. The IsoSol-S100 solutions can be produced at far higher production capacity than density-gradient centrifugation (DGU) or chromatography-based production techniques and at a lower cost. The highly graphitized starting material and low sonication intensity utilized during the extraction process minimizes damage to the nanotubes, allowing the material to exhibit higher crystallinity and longer average lengths of 2µm, as compared to aqueous surfactant-wrapped nanotubes. The patent-pending polymer-wrapping technique used by Raymor-NanoIntegris was developed by the National Research Council Canada within the Printable Electronics Program. It takes advantage of the selective affinity of conjugated polymers for semiconducting carbon nanotubes and surmounts the capacity bottleneck presented by competing technologies. The IsoSol-S100 material is now available to the academic community and to leading companies working in the field of printed transistors, nanotube-based electronics, and sensors.

Raw | <35% wt% | 0.8 – 1.2 | ~100 – 1,000 nm We currently offer our HiPco Raw nanotube products in two forms: Fluffy Powder and Wet Cake. Due to safety concerns with handling the extremely low-density raw material, the HiPco Raw product is provided as a wet cake for orders of greater than 5g unless otherwise requested. The wet cake is roughly 10wt% nanotubes. The remaining mass is a mixture of 10% ethanol and 90% water, which can be easily removed by thermal or centrifugal treatment. (e.g. 10.70g of wet cake will be provided for a 1g HiPco Raw SWNT order.

Semiconducting SWNT’s Overview FE-SEM of IsoNanotubes-S Thick Film Image by Najia Mahdi of NORCADA Diameter Range 1.2nm-1.7nm Length Range 300 nm to 5 microns Solution Color Light Crimson/ Pink Metal Catlyst Impurity<1% Amorphous Carbon Impurity 1-5% Electronic Enrichment 90%, 95%, 98%, 99%, and 99.9% Product Applications The IsoNanotubes-Semiconducting product has been successfully utilized in numerous scientific works over the years. The primary usage for the IsoNanotubes-S material is for the creation of thin film transistors. Because of the IsoNanotubes-S’ high single-walled nanotube purity, length, pristine surface, and semiconducting properties, this material has proven beneficial in applications such as Gas Detection, Temperature Sensing, CMOS circuit creation, and has laid the ground work for the development of novel and exciting technological advancements. Temperature Sensing/ Wearable Devices Mechanically flexible CMOS digital and analog circuits were fabricated on a polyimide substrate by monolithic ingegration of n-type TFTs, p-type CNT-TFTs, and a temperature sensor made of CNTs and PEDOT:PSS, with the CNT source being NanoIntegris’ IsoNanotubes-S 99% solution. [1] The following electrical properties of the CNT-TFTs were found: field-effect mobility of 9.95 ±2.08cm 2 V-1 s-1, on-current (I on)/off-current (I off) ratio (Log I on/I off) of 4.65 ±0.70V and threshold votage of -1.63 ±0.24V. The flexible CMOS J-K flip flop digital circuit was also found to a memory function demonstrated when 5 or 0 Volts were applied to the J and K inputs. When operated, the power consumption at steady state was ~68.7nW/mm and 6.34 µW/mm with an applied CLK signal. It was also found that the electrical properties remained unchanged (no malfunction or TFT leakage) with a bending radius of 5.6mm and 500 bending cylces. Additionally, analog circuits were fabricated in the form of a differential amplifier. The circuit produced a peak gain of ~31.7dB, corresponding to a 38.5 times amplification. This amplified was utilized to fabricate a temperature sensor in which the electrical resistance was decreased with increasing temperature. In the temperature range of 28 and 34°C, the rate of voltage change was found to be 0.4V/°C when using the amplifier, with a range that can be tuned by changing the input voltage. Such an approach can used for creating wearable devices for monitoring skin temperature. [1] Adv. Mater. Technol. 2016, 1, 1600058. Gas Detection Members of the Sensor System Research Center at the Korea Institute of Science and Technology have created a highly sensitive gas detector by using platinum nanoparticles decorated with NanoIntegris’ IsoNanotubes-S 99% single-walled carbon nanotubes. [1] These sensors were able to detect numerous gases such as NO2, NO, C6H6, C7H8, C3H6O, CO, and NH3 but proved the most successful in the detection of nitrogen dioxide (NO2) at sensitivities down to 2ppm. It was also greatly promising to find that the sensors showed almost complete recovery (~95%) and facilitated both chemisorption and dissociation of NO2 molecules.

Product Delivery We currently offer our nanotube products in two forms: Aqueous surfactant solution and surfactant-eliminated “powder” (thick film or buckey paper). We remove the surfactant from our powders via a proprietary process that involves filtration and rinsing. The end result is a film-like structure, as can be seen in the above picture, bearing a density around 1mg/ 4.8cm 2. Our powders have been formulated so that they are easy to use, break apart, and disperse in solvents with gentle sonication. Prices Multi-gram and kilogram price quotes available by request. Additional discounts also available for large volume orders. To place an order contact our Sales Manager at sales@nanointegris.com or call +1-866-650-0482.
