CNT/Graphene Dispersion

SWCNT dispersion: In biomedical applications, the potential of carbon nanotubes based materials has been widely used in recent years. The preparation of the single-wall carbon nanotube (SWCNT) with the biocompatibility of these composite is investigated. Colloidal processing is a recognized tool for the preparation of SWCNT-based materials and regulation of their stability.

Single-walled Carbon nanotubes (SWCNTs) demonstrate many attractive electrical, mechanical and thermal properties with the potential of their applications in engineering, electronics, and medicine. The different types of electrochemical biosensors, piezoresistive strain sensors, electromagnetic switches, electrical energy and memory storage devices, supercapacitors, multifunctional polymer nanocomposites, materials for heat transfer devices, ion battery, ultrafast photonics, sorbents, biopharmaceutics, and tissue engineering.The quality of SWCNT dispersion in suspensions and derived functional composites may be particularly important in the determination of electrical, mechanical and thermal properties of these systems.

Single-walled carbon nanotubes (SWCNT) dispersion are widely used as structural composites, and also in energy applications such as the lithium-ion battery. SWCNT can be found in final products such as conductive polymers and composites (automobile and electronic), aerospace structural parts, sporting goods, and sensors.

The excellent mechanical, electrical, thermal, and chemical properties of carbon nanotubes (CNTs) and graphene have attracted considerable attention for applications at the macroscale. Polymer composite fabrication is a common method used to assemble SWCNT- and graphene-based macroscale products; however, this method has been limited by the agglomeration of carbon nanomaterials in the polymer matrix. Sufficient dispersion of individual CNTs and graphene in the polymer host is required to retain the intrinsic properties of the nanofillers.

SWCNTs are really small diameter fibers subjected to a high-temperature heat treatment in an inert atmosphere. The covalent carbon-carbon bonds within a CNT are among the strongest known. In addition, CNTs are remarkably compliant, i.e., they are able to make sharp bends without fracture. It is therefore expected that CNTs could be incorporated in revolutionary lightweight composites. To perfect these CNT composites, challenges exist in their dispersion into the host and also in developing strong, a covalent coupling of the CNT to the host medium.
