ENHANCEMENT OF MECHANICAL AND ELECTRICAL PROPERTIES OF EPOXY-BASED COMPOSITES FILLED WITH INTACT OR OXIDIZED CARBON NANOTUBES

Graphene and carbon nanotubes have a Steiner minimum tree structure, which endows them with extremely good mechanical and electronic properties. A modified Hall-Petch effect is proposed to reveal the enhanced mechanical strength of the SiC/graphene composites, and a fractal approach to its mechanical analysis is given. Fractal laws for the electrical conductivity of graphene, carbon nanotubes and graphene/SiC composites are suggested using the two-scale fractal theory. The Steiner structure is considered as a cascade of a fractal pattern. The theoretical results show that the two-scale fractal dimensions and the graphene concentration play an important role in enhancing the mechanical and electrical properties of graphene/SiC composites. This paper sheds a bright light on a new era of the graphene-based materials.

Highly Sensitive

Flexible strain sensors with superior flexibility and high sensitivity are critical to artificial intelligence. And it is favorable to develop highly sensitive strain sensors with simple and cost effective method. Here, we have prepared carbon nanotubes enhanced thermal polyurethane nanocomposites with good mechanical and electrical properties for fabrication of highly sensitive strain sensors. The nanomaterials have been prepared through simple but effective solvent evaporation method, and the cheap polyurethane has been utilized as main raw materials. Only a small quantity of carbon nanotubes with mass content of 5% has been doped into polyurethane matrix with purpose of enhancing mechanical and electrical properties of the nanocomposites. As a result, the flexible nanocomposite films present highly sensitive resistance response under external strain stimulus. The strain sensors based on these flexible composite films deliver excellent sensitivity and conformality under mechanical conditions, and detect finger movements precisely under different bending angles.
