Process of forming covalent bonds or relatively short sequences of chemical bonds to join two polymer chains together.
Copolymers
Homopolymers
Crosslinking
Elastomer
A natural or synthetic polymer having elastic properties, e.g. rubber.
Copolymers
Homopolymers
Elastomer
Crosslinking
Polymers consisting of monomer of identical chemical structure
Crosslinking
Elastomer
Copolymers
Homopolymers
A heat-resistant and strong synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, this high-strength material was used first commercially in the early 1970s as a replacement for steel in racing tires.
Kelvin
Kevlar
Monomer
Polymer
a molecule that can be bonded to other identical molecules to form a polymer.
Polymer
Monomer
Kelvin
Kevlar
A large molecule which is formed by repeated linking of small molecules called "monomers"
Monomer
Kevlar
Kelvin
Polymer
The process by which simple (monomer) molecules join together to form very large (polymer) molecules.
Polymerization
Resin
Thermoplastic
Thermoset
A solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers.
Thermoset
Polymerization
Thermoplastic
Resin
A material, usually a plastic polymer, which becomes more soft when heated and hard when cooled.
Polymerization
Thermoplastic
Resin
Thermoset
A polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin.
Thermoplastic
Thermoset
Resin
Polymerization
A process of treating natural rubber with sulphur
Vulcanization
Thermoplastic
Polymerization
Thermoset
Includes the miniaturization of materials components (up to atomic level) with further selfassembly process leading to the formation of nanostructures
Bottom-up Approach
Buckminsterfullerene
Carbon nanotubes
Dendrimers
Also known as buckyball, is a spherical close- caged structure made of sixty sp2 carbons it has a highly symmetrical structure which give it its electronic properties
Carbon nanotubes
Dendrimers
Buckminsterfullerene
Bottom-up Approach
Are tubes made of carbon with diameters typically measured in nanometers; often refer to single-wall carbon nanotubes (SWCNTs) with diameters in the range of a nanometer.
Bottom-up Approach
Buckminsterfullerene
Carbon nanotubes
Dendrimers
Are highly branched, star-shaped macromolecules with nanometer-scale dimensions
Bottom-up Approach
Buckminsterfullerene
Carbon nanotubes
Dendrimers
Materials with sizes 1 to 100 nanometers and are intentionally produced for specific product application
Engineered nanomaterials
Fullerene
Graphene
Nanocomposites
An allotrope of carbon whose molecule consists of carbon atoms connected by single and double bonds so as to form a closed or partially closed mesh, with fused rings of five to seven atoms. The molecule may be a hollow sphere, ellipsoid, tube, or many other shapes and sizes.
Nanocomposites
Graphene
Fullerene
Engineered nanomaterials
A carbon-based nanomaterial derived from graphite through exfoliation
Engineered nanomaterials
Graphene
Nanocomposites
Fullerene
Are materials that incorporate nanosized particles into a matrix of standard material. The result of the addition of nanoparticles is a drastic improvement in properties that can include mechanical strength, toughness and electrical or thermal conductivity.
Nanocomposites
Fullerene

Nanoparticles
Nanocomposites
Nanomaterials
The design, synthesis, and application of materials and devices whose size and shape have been engineered at the nanoscale
Nanotechnology
Nanoparticles
Nanocomposites
Nanomaterials
Uses larger (macroscopic) initial structures, which can be externally-controlled in the processing of nanostructures
Top-down Approach
Downward Approach
