The material and the manufacturing method were originally developed in the Nanoscience Center of the
University of Jyväskylä
The University of Jyväskylä ( fi, Jyväskylän yliopisto) is a research university in Jyväskylä, Finland. It has its origins in the first Finnish-speaking Teacher Training College (the so-called Teacher Seminary), founded in 1863. Ar ...

Ultrasound is used to disperse the nanotubes and to create
radicals at the ends of CNT molecules.

CNTs can then chemically react with
epoxy
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also coll ...
resin or other material forming strong
covalent bond
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms ...
s. This results in a more durable hybrid composite structure that is between 20% and 30% stronger (with only 0.5% CNT contents) than a conventional reinforced plastic.
The manufacturing process allows controlling the material properties such as
electrical conductivity
Electrical resistivity (also called specific electrical resistance or volume resistivity) is a fundamental property of a material that measures how strongly it resists electric current. A low resistivity indicates a material that readily allow ...

thermal conductivity
The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by k, \lambda, or \kappa.
Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal ...
and
viscosity
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.
Viscosity quantifies the inte ...
