Copper nanoparticles are well known to be copper based particles of size ranging between 1 and100 nm. Unlike, any other nanoparticles; the copper nanoparticles are formed by the synthesis of copper nanoparticles which is completely a chemical process.
Copper nanoparticles synthesis – Manufacturing process
Copper nanoparticles are manufactured using various techniques. The most suitable method amongst all is the electro deposition. The electrolyte used for this particular copper nanoparticles synthesis process is aqueous solution acidified using copper sulfate with certain additives.
A spongy layer of the copper particles is usually deposited on the cathode surface when DC input voltage is usually varied along with the constant current. The surface characterization is done using SEM and TEM.
The left over copper nanoparticle is treated to affect the dispersion performance. Therefore, copper nanoparticles are sealed beneath the vacuum and are stored in a cool and warm place. Bear in mind, during copper nanoparticles synthesis, these particles should not be exposed either to air and also should not be subjected to stress.
Few copper nanoparticles Applications
The vital applications of copper nanoparticles are listed below-
It is used as lubricant additives.
EMI shielding.
It heat sink and considered as highly thermal conductive materials.
It is considered as an effective catalyst for all sort of chemical reactions.
It is considered as a capacitor materials.
Conductive pastes and inks which contains copper nano-particles can also be used as substitute for certain expensive metals which are used in the printed electronics, displays as well as in the thin film applications.
It can also be used as superficial conductive coating in the processing of metals and non-metals.
It helps in the production of internal electrodes as well as other electronic components. They are used for miniaturizing the microelectronic devices.
Most of the online suppliers give attractive offers on the sales you need to be focused get the benefits effectively, before you buy copper nanoparticles it is better suggested to check with the profile of the suppliers.
