Abstract: Disclosed herein are novel methods to handling carbon nano materials and forming composite materials from carbon nano materials and polymers such as polyurethane and polyurea materials. Such novel methods provide a number of benefits to a polymer processor and end user of any resulting materials or products. As disclosed herein, methods of incorporating carbon nano materials into polymers can achieve benefits regarding electrical properties, modulus, and thermal stability as well as other benefits. However, enhancing and creating such improvements in material properties must be done with care because creating or enhancing one property does not always result in the creation or improvement in other properties. For example, thermal stability, electrical conductivity, and mechanical properties can be optimized in different ways, and at different loadings of differing carbon nano materials.

Abstract: The present disclosure describes embodiments of novel methods and processes for forming CNT dispersions in media using a basket milling process. In particular, the methods and processes disperse CNT without damaging individual particles or affecting the properties of the particles. Testing of such methods demonstrates that recirculatory milling processes can be used to disperse SWNCT effectively and efficiently in a media.

Abstract: The present disclosure describes embodiments of novel methods of few layer graphene exfoliation and stabilization using an effective liquid additive package and laminar shear processing regimen. The liquid additive package serves both as a stabilizer and solvent for milling of the dispersion of graphene in media. The novel methods create suitable functionalities on graphene particles and compatibility between the graphene and polymer, which results in stronger interfacial interaction and complete exfoliation. The complete exfoliation of graphene and substantial interfacial interaction between graphene and the polymer matrix have a significant positive impact on the electrical, thermal, and mechanical properties of the composite.

Abstract: A solventborne pigment dispersion having a volatile organic chemical (VOC) content that is less than 250 g/L for tinting solvent-based surface coatings is formulated using a vegetable oil-derived solvent component that is one or more methyl esters of vegetable oils, an acrylic resin containing at least 60% solids, one or more highly concentrated surfactants containing up to 100% by weight of active constituents and that contains no PMA or free aromatic moieties, and one or more organic pigments or one or more inorganic pigment, or a combination thereof.
