“…Hejazi et al [64] applied pressing of CNT into the in situ melting hydrophilic polyurethane matrix, and claimed the leading role of roughness in the formation of superhydrophobic surfaces. Pila et al [65] reported the application of SWCNH in composites with polyurethane which led to improvement in the mechanical properties. Tanaka et al [66] reported the SWCNH composites with polyimide, and observed wear reduction of the material.…”
