New Type

Dielectric elastomers (DEs) have been attracting great attention in the field of electro-mechanical actuation and sensing. In this paper, we develop a new type of silicone-based DEs by incorporating multiwalled carbon nanotubes (MWNTs) to the DEs as fillers. The dispersion of MWNTs during the material processing plays a significant role in deciding the final properties of the nanocomposites. In this work, acetone and ultrasonication along with characterization tools such as scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are utilized to examine the MWNT dispersion quality within DE nanocomposites. Furthermore, microstructural MWNT dispersion and filler–matrix interfacial bonding as well as the overall dynamic mechanical responses are investigated to reveal the correlation between them. It is concluded that the processing of DE nanocomposites strongly affects the dynamic mechanical properties, which can inversely provide with microstructural information for the nanocomposites.

The basic and dynamic mechanical properties and thrermal conductivity of rubber composites filled with carbon nanotubes (CNTs) and various particle-sized carbon blacks (CB) were investigated. Results indicated that tear strength and modulus at a definite elongation of rubber composites filled with CNTs were enhanced compared to the conventional CB filler. However, tensile strength and elongation at break became lower. Thermal conductivity of rubber composites partly filled with CNTs is higher than those filled with CB. Rubber filled with the combination of CNTs and the bigger CB particles was beneficial to improve wet-resistant performance and roll resistance of elastomer such as tire.
