In the rapidly evolving world of advanced materials, conductive polymer nanocomposites have emerged as a game-changer, bridging the gap between traditional polymers and the need for electrical conductivity in diverse applications. The composites are prepared by blending conductive nanomaterials such as graphene and carbon nanotubes (CNTs) into a polymer matrix.
What Are Conductive Polymer Nanocomposites?
Conductive polymer nanocomposites are specifically designed materials. They are made from a polymer base and small fillers to provide electric conductivity. It is achieved without sacrificing the inherent benefits of polymers, such as flexibility, ease of processing, and lightness.
Use of Masterbatches in Conductivity
Masterbatches are concentrated mixtures of nanomaterials dispersed in a carrier polymer. They provide even dispersion of graphene or carbon nanotubes in the final composite and make the production process easier. Upon addition to polymer matrices, even a small concentration (ranging from 0.5% to 5%) of such nanomaterials can become a major contributor to the electrical and thermal conductivity of the composite.
Why Graphene and Carbon Nanotubes?
Graphene and CNTs are renowned for their extraordinary electrical, mechanical, and thermal properties:
- Graphene: A single layer of carbon atoms arranged in a honeycomb lattice, graphene offers high electrical conductivity, excellent mechanical strength, and large surface area.
- Carbon Nanotubes: CNTs are cylindrical carbon structures with remarkable tensile strength and conductivity, capable of forming conductive pathways in polymer matrices.
Key Applications
Conductive polymer nanocomposites are highly flexible and can be used in many industries and businesses.
- EMI Shielding: Applied in cases of electronics to prevent electromagnetic interference.
- Anti-Static Packaging: Prevents static accumulation in packaging for delicate electronics.
- Flexible Electronics: Enables the development of flexible circuitry, touch screens, and wearable sensors.
- Battery Components: Enhances conductivity in battery casings, separators, and electrodes.
- Automotive Parts: Enhances performance and durability of electronic connectors and fuel system components.
Advantages:
Unlike traditional conductive fillers like carbon black or metal powders, graphene and CNTs offer superior performance at much lower loadings, preserving the lightweight and flexible nature of the base polymers. They also enhance mechanical strength, thermal stability, and durability.
