Abstract: New methods for preparing carbon nanotube films having enhanced properties are provided. The method broadly provides reacting carbon nanotubes (CNTs) and compounds comprising a polyaromatic moieties in the presence a strong acid. During the reaction process, the polyaromatic moieties noncovalently bond with the carbon nanotubes. Additionally, the functionalizing moieties are further functionalized by the strong acid. This dual functionalization allows the CNTs to be dispersed at concentrations greater than 0.5 g/L in solution without damaging their desirable electronic and physical properties. The resulting solutions are stable on the shelf for months without observable bundling, and can be incorporated into solutions for printing conductive traces by a variety of means, including inkjet, screen, flexographic, gravure printing, or spin and spray coating.

Abstract translation: 提供了制备具有增强性能的碳纳米管膜的新方法。 该方法广泛地提供了在存在强酸的情况下使碳纳米管（CNT）和包含多芳族部分的化合物。 在反应过程中，多芳族部分与碳纳米管非共价结合。 此外，官能化部分进一步由强酸官能化。 这种双官能化允许CNT在溶液中以大于0.5g / L的浓度分散，而不损害其所需的电子和物理性质。 所得到的溶液在搁板上稳定几个月，不需要可观察到的捆扎，并且可以通过各种方式（包括喷墨，筛网，柔性版，凹版印刷或旋涂和喷涂）结合到用于印刷导电迹线的溶液中。

Abstract: Materials and methods to immobilize photoacid generators on semiconducting substrates are provided. PAG-containing monomers are copolymerized with monomers to allow the polymer to bind to a surface, and optionally copolymerized with monomers to enhance solubility to generate PAG-containing polymers. The PAG-containing monomers can be coated onto a surface, where the immobilized PAGs can then be used to pattern materials coated on top of the immobilized PAGs, allowing direct patterning without the use of a photoresist, thereby reducing process steps and cost. The disclosed materials and processes can be used to produce conformal coatings of controlled thicknesses.
