What are Nanocomposites?
Nanocomposites are materials that incorporate
nanoscale fillers into a matrix to improve or tailor the properties of the base material. These fillers can be in the form of nanoparticles, nanotubes, or nanofibers, and they are typically dispersed within a polymer, metal, or ceramic matrix. The resulting nanocomposites often exhibit superior mechanical, thermal, and electrical properties compared to their conventional counterparts.
Why are Nanocomposites High Performing?
The high performance of nanocomposites stems from the unique properties of nanoscale materials and their interactions with the matrix. For instance,
carbon nanotubes have extraordinary tensile strength and electrical conductivity, which can be imparted to the composite material. Similarly,
nanoclays can improve the barrier properties and thermal stability of polymers. The high surface area to volume ratio of nanomaterials also plays a crucial role in enhancing the interfacial interactions, leading to improved mechanical properties.

Challenges in Nanocomposites Development
Despite their potential, the development of high performance nanocomposites faces several challenges: Dispersion: Achieving uniform dispersion of nanomaterials within the matrix is critical for consistent properties but is technically challenging.
Compatibility: Ensuring compatibility between the nanomaterials and the matrix to avoid phase separation and agglomeration.
Scalability: Developing scalable and cost-effective manufacturing processes for industrial applications.
Environmental Impact: Addressing the potential environmental and health impacts of nanomaterials during production and usage.
