Minimum Federal Safety Standards for corrosion control on buried oil & gas pipelines stipulate that metallic pipes should be properly coated and have impressed-current cathodic protection (ICCP) systems in place to control the electrical potential field around a protected pipe. In certain examples described herein, electrically-conductive composites can be used and provide intrinsically-safe materials without the dielectric shielding issues of existing materials used with pipelines. As reacted by customary spray applications, the nanocomposite foams described herein are directly compatible with ICCP functionality wherever foam contacts the metallic pipe. Various compositions and their use with underground and/or above ground pipelines are described.
