Nanoparticles Surfactant / Nanopowder Dispersant

Research grade nanopowder dispersants / nanoparticles surfactants.
The below surfactants / dispersants are based on our lab experimental results from numerous dispersants screened out for making nanoparticles dispersion products.

1) Research grade nanopowder dispersants / nanoparticles surfactants for aqueous dispersion products.
It is a clear viscous fluid
with a solid content of 45%it possesses the hydrogen bonding of its hydrophilic polyethylene oxide parts. It is an ideal surfactant for making aqueous dispersion products. Usage: 5-10wt% (max 20%) of material total weight

$45/15ml - surfactants for aqueous dispersion
$75/30ml - surfactants for aqueous dispersion
$115/60ml - surfactants for aqueous dispersion
$198/120ml - surfactants for aqueous dispersion

2) Research grade nanopowder dispersants / nanoparticles surfactants for alcohol dispersion products.
It is a clear viscous fluid
with a solid content of 45%. It is suitable for solutions: trichloroethylene, ethylene glycol, ethyl ether, ethyl alcohol, isopropyl alcohol, ethylene dichloride and toluene, xylene. Usage: 5-10wt% (max 20%) of material total weight

$45/15ml - surfactants for alcohol dispersion
$75/30ml - surfactants for alcohol dispersion
$115/60ml - surfactants for alcohol dispersion
$198/120ml - surfactants for alcohol dispersion

3) Research grade nanopowder dispersants / nanoparticles surfactants for ester dispersion products.
It is a clear viscous fluid
with a solid content of 45%. The solvent is a mixture of butyl acetate and ethylene glycol butyl ether. Based on our lab experimental results from numerous dispersants screened out, it is particularly suitable for nanoparticles / nanopowder to be dispersed in ester solvents such as ethyl acetate, butyl acetate, and the liquid epoxy resin.. Usage: 5-10wt% (max 20%) of material total weight.

$65/15ml - surfactants for ester dispersion
$118/30ml - surfactants for ester dispersion
$195/60ml - surfactants for ester dispersion
$378/120ml - surfactants for ester dispersion

4) Research grade nanopowder dispersants / nanoparticles surfactants for oil and organic solvents dispersion products.
It is a amber viscous fluid
with a solid content of 75%. It is suitable for solutions: oil ans organic solvents. Usage: 3wt% (max 5%) of material total weight

$75/15ml - surfactants for oil dispersion
$118/30ml - surfactants for oil dispersion
$195/60ml - surfactants for oil dispersion
$378/120ml - surfactants for oil dispersion

5) Research grade nanopowder / nanoparticles powdery polymer dispersant.
It is a powdery polymer dispersant for water/ethanol/ester/exylene solvents and many other different solvents for making dispersion products.
Based on our lab experimental results from numerous dispersants screened out, the dispersant not only can greatly help nanopowder / nanoparticles to be dispersed, but also can prevent nanopowder / nanoparticles from settlling down in solution for longer time. Usage: 5-10wt% (max 10%) of material total weight.

$95/15g - powdery polymer dispersant
$158/30g - powdery polymer dispersant
$258/60g - powdery polymer dispersant
$398/120g
 - powdery polymer dispersant

How to disperse nanopowder and nanoparticles?
1) Step 1, add surfactant / dispersant into solution first. Step 2, when surfactants / dispersants are fully dissolved into the solution, add nanopowder / nanoparticles. Step 3, finally, ultrasonicate the solution (this requires the customer's own experience).
2) During ultrasonic processing, the dispersion may heat up, therefore it is a good idea every 5min to stop, wait for solution to cool, defoam, before continuing. Total 30 minutes: 5min x 6 times.
3) At the end of the ultrasonication, centrifuge the dispersion solution, remove non-dispersed agglomerated particles. Centrifugal speed should be 2000r/min, centrifugation time of 30 min. After centrifugation, the dispersion will be stable for a certain time based on materials particle size, concentration, and molecular weight ..... 

Making Nanopowder / Nanoparticles Dispersion Product Equipments:
(1) Ultrasonic dispersion device: ideal for laboratory-scale, low-viscosity media to disperse Nanopowder; (2) Grinding dispersion equipment: suitable for large-scale nanopowder dispersion product, middle-viscosity media to disperse nanopowder; (3) Combination method: "first grinding, second ultrasonic dispersion " can be efficiently and stably to disperse nanopowder.
***Equipment capacity, dispersion volume, dispersion concentration also need to be considered...
