nanocomposite

Syllable breakdown

Dictionary meaning

a multiphase material in which at least one phase has one or more dimensions in the nanometre range, combining a matrix material — polymer, metal, or ceramic — with nanoscale reinforcing or functional fillers — nanoparticles, nanofibres, nanotubes, or nanoplatelets — to produce properties superior to those achievable with conventional composite materials; the nanoscale dimensions of the filler phase provide extraordinary surface area for interfacial bonding with the matrix, enabling large property improvements at low filler loadings; polymer-clay nanocomposites achieve significant improvements in mechanical stiffness, barrier properties, and flame retardance; carbon nanotube nanocomposites offer enhanced electrical conductivity and mechanical strength; nanocomposites are used in packaging, automotive components, aerospace structures, sporting equipment, and biomedical implants

Examples

• Nanocomposite packaging films incorporating clay nanoplatelets reduce oxygen permeability and extend food shelf life.
• Carbon nanotube nanocomposites used in aircraft fuselages reduce weight while maintaining structural strength.
