Carbon Nanotube Composites

Carbon nanotube-reinforced polymer composites were fabricated by high shear mixing. The microstructure and the electrical properties of the carbon nanotube–polymer composites were investigated by scanning electron microscopy and electrical resistance measurement. We found that the carbon nanotube composites showed high electrical conductivity (1.5 S m−1) at 7.0 wt% of carbon nanotubes, and the increase in thickness enhanced the electrical conductivity of the composites. The multifunctional properties of the carbon nanotube composites were also investigated for use in sensing the freezing temperature and also in deicing by self-heating. The results showed that the carbon nanotube–polymer composites had high temperature sensitivity in the freezing temperature range from −5 to 5 C and an excellent heating performance due to the Joule heating effect. The carbon nanotube composites are promising to be used as smart coating materials for deicing by self-heating as well as by detection of the freezing temperature.

Volume Effects

Hybrid Carbon nanotube (CNT) composites consisting more than two different kind fillers have received considerable attention which could improve electrical conductivity and mechanical properties. Incorporation of micro-scale second filler, excluded volume is created that effectively creates a segregated network of nanotube. Even if there were successful trials with theoretical model in second filler composite system, it was not fully understood how the electrical conductivity increase with respect to shape (or size) of second filler. Aim of the present research is an understanding of size effect of particulate filler on electrical resistivity of carbon nanotube polymer composites. Depending on size of particulate filler, conductivity of carbon nanotube polymer composites are changed (increase or decrease) indicating there is transition of excluded volume effects. For example, enhanced conductivity was observed in cooperation with micro-size second filler while decreased conductivity was observed for nano-size filler.
