The CNT were organized along crystallite domains during a directional freezing process and subsequently fixed by the gamma irradiation induced polymerization and crosslinking in solid state. Different morphology and distribution of CNT in fabricated and conventionally prepared composites were investigated by scanning and transmission electron microscopies. The interactions in the polymer matrix were elucidated by a broad dielectric spectroscopy. Importantly, the composite exhibited anisotropic electrical and mechanical properties studied by electrical conductivity measurement and dynamic mechanical analysis, respectively. Differences of two orders of magnitude in the electrical conductivity and 5 times higher storage modulus at 10- 2 Hz in the direction along and perpendicular to freezing in composite with 0.1% CNT in feed were observed.
