Resumo

In this paper we describe a way to prepare hybrid functional polymer materials (HFPMs) based on epoxy binders that contain functionalized carbon nanotubes and a compatibilizer (Cherflon tetrafluoroethylene telomer). A micropattern has been found to form on the prepreg surface in the lack of external pressure that ensures high-level hydrophobicity (the wetting angle is 144.3°). We also offer a method for the formation of a hydrophobic pattern on a cured plastic surface (the wetting angle reaches 136° for water). The lateral and transverse specific volume resistances of the studied HFPM sample with respect to the reinforcer packing plane are 19 Ω cm and 6.7 × 102 Ω cm. A 0.68-mm-thick HFPM film was found to transmit ca. 1% and to reflect 75–80% of the incident electromagnetic power in the 27–34 GHz frequency range.
