What is difference between composites and nanocomposites?
As nouns the difference between composite and nanocomposite is that composite is a mixture of different components while nanocomposite is any composite material one or more of whose components is some form of nanoparticle; more often consists of carbon nanotubes embedded in a polymer matrix.

What is epoxy resin in dentistry?
epoxy resin a tough, chemically resistant, adhesive, flexible, dimensionally stable resin of epoxy polymers; used as denture base material.
How are nanocomposites made?
Nanocomposites are the heterogeneous/hybrid materials that are produced by the mixtures of polymers with inorganic solids (clays to oxides) at the nanometric scale. Most popularly, nanocomposites are prepared by the process within in situ growth and polymerization of biopolymer and inorganic matrix.
Why are nanocomposites better than composites?
Nanocomposites have a higher strength to weight ratio than carbon fiber or glass fiber reinforced composites. The tensile strength of carbon fiber is 6,300 MPa with a specific strength of 2,457 kN x m/kg while that of carbon nanotubes is 23,000 MPa and a specific strength of 45,268 kN x m/kg.
What are metal nanocomposites?
Metal based nanocomposites are gaining popularity for the past few years due to their promising chemical and physical properties. These nanocomposites can be obtained by incorporation of metal nanoparticles with glass, ceramic and polymer.
Is epoxy used in dentistry?
Composite carbon/epoxy resin techniques for restorative dentistry have improved with the development of various composite resins classified according to fiber reinforcement, such as short fibers, woven materials, or long unidirectional fibers.
What resin do dentists use?
Dental composite resins consist of a mixture of monomers and are most commonly based on bisphenol-A glycidyl methacrylate (bis-GMA).
What is metal matrix nanocomposites?
Metal matrix nanocomposites (MMNCs) comprises of metal as the matrix and ceramic as the reinforcement. This type of composites can be classified as continuous and non-continuous reinforced materials. CNT-MMNC provides high tensile strength and electrical conductivity as compared to carbon nanotube materials.
What is polymer matrix nanocomposites?
A polymer nanocomposite is a composite material comprising a polymer matrix and an inorganic dispersive phase that has least one dimension that is nanometric in scale.
What is composite made of dentistry?
Composite resin fillings are a popular alternative to silver fillings. They are made of a plastic substance called acrylic resin that is reinforced with powdered glass quartz, silica, or other ceramic particles.
