    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. Thus, it is necessary to carefully consider a number of factors when designing methods for incorporating carbon nano materials into polymers.

    Abstract: Provided is a hollow structure for fuel, in which a conductive layer containing a fluororesin is used; that is excellent in fuel barrier properties and low-temperature impact resistance, and further is excellent in interlayer adhesion,
    The hollow structure for fuel includes a polyamide rein layer (A) a polyamide resin layer (B), a polyamide resin layer (C), and a conductive layer (D) in this order from an outside. The polyamide resin layer (A) contains a polyamide resin (a). The polyamide resin layer (B) contains a polyolefin, a polyamide resin (b1) containing a structural unit derived from metaxylylenediamine and a structural unit derived from an aliphatic dicarboxylic acid having from 4 to 8 carbon atoms, and a polyamide resin (b2) containing a structural unit derived from xylylenediamine and a structural unit derived from an aliphatic dicarboxylic acid having from 9 to 12 carbon atoms. The polyamide resin layer (C) contains a polyamide resin (c). The conductive layer (D) contains a fluororesin and a conductive substance.
