Thermal diffusivity of nanocarbon composites. - In: Polymer composites, ISSN 1548-0569, Bd. 32 (2011), 1, S. 14-17
This study was performed to measure the thermal diffusivity of different types of nanocarbon composites. Thermoexfoliated graphite (TEG), ultrasonically dispersed TEG, and multiwalled carbon nanotubes were used as fillers in epoxy polymer matrixes. The nanocarbon filler content was 1-10 wt%. The temperature dependence of the thermal conductivity and the heat capacity were extensively characterized in the temperature range between 150 and 425 K. For this purpose, the thermal diffusivity of the composites was investigated by two experimental methods: dynamic A-calorimeter and photoacoustic. The comparative analysis of thermal diffusivity of compacted TEG samples with different densities and of nanocarbon-epoxy with different filler content was carried out. It was found that for the composites with a low distribution of the nanocarbon filler, the thermal diffusivity increases and that the value is determined by the structural and morphological properties of the filler. The orientation function for the TEG-epoxy composites and the compact TEG samples differs due to the epoxy matrix that reduced anisotropy of the composite. POLYM. COMPOS., 2011.

Penetration based CNT/Sol-Gel composite films and their remarkable electrical properties. - In: Microelectronic engineering, Bd. 88 (2011), 8, S. 2513-2525
In this work we present a novel method for CNT/Sol-Gel film preparation, combining low resistivity and improved adhesion behaviour on glass substrates. Naturally occurring voids, with diameters of 50-100 nm, in sprayed CNT networks are used for SolGel penetration via dip coating method. Thermal treatments, for composite film densification, in the range of 200-700 ˚C are investigated and electrical properties were compared to identically treated reference samples with the same batch of nanotubes but without Sol-Gel. The resistivity of such composite films, with best value of similar to 0.03 Omega cm for MWNTs, is two orders of magnitudes lower than previously reported for CNT/Sol-Gel composites. Surprisingly the surface resistance of the composite film shows 25% improvement compared to thermally equal treated pure CNT films. In addition, crosscut adhesion behaviour is investigated, including tape test, showing good performance for composite films, where Sol-Gel acts as an adhesion promoter.
