Abstract

An apparatus for manufacturing nanocomposite-ink, the apparatus comprising, a nanoparticle reservoir, an organic-matrix reservoir, a homogenizer, and a dispenser. The homogenizer combines the nanoparticles and the organic-matrix, dispersing the nanoparticles within the organic-matrix, thereby producing a nanocomposite-ink for dispensement by the dispenser.

Claims (32)

1. An apparatus for manufacturing nanocomposite-ink, the apparatus comprising:

a nanoparticle reservoir;

a nanoparticle continuous flow reactor with a first energy source for nanoparticle nucleation and a second energy source for nanoparticle growth;

an organic-matrix reservoir;

a homogenizer that disperses the nanoparticles within the organic matrix; and

a dispenser, wherein the homogenizer combines the nanoparticles and the organic-matrix, dispersing the nanoparticles within the organic-matrix thereby producing a nanocomposite-ink for dispensement by the dispenser.

2. The apparatus of claim 1 , further comprising an optical monitor.

3. The apparatus of claim 1 , further comprising an ink dump.

4. The apparatus of claim 1 , wherein the dispenser has an interfaces that is compatible with an inkjet cartridge.

5. The apparatus of claim 1 , wherein the apparatus has a plurality of organic-host reservoirs.

6. The apparatus of claim 1 , wherein the apparatus has a plurality of nanoparticle reservoirs.

7. The apparatus of claim 1 , wherein the homogenizer has a sonifier.

8. The apparatus of claim 1 , wherein the homogenizer has static mixing members.

9. The apparatus of claim 1 , wherein the homogenizer has active mixing members.

10. The apparatus of claim 1 , wherein the homogenizer has high shear mixers.

11. The apparatus of claim 1 , wherein the apparatus further comprises of plurality of nanocomposite-ink reservoirs, each of the plurality of nanocomposite-ink reservoirs storing the nanocomposite-ink.

12. The apparatus of claim 11 , wherein the plurality of nanocomposite-ink reservoirs have an agitator to keep the nanoparticles dispersed in the organic-matrix.

13. The apparatus of claim 1 , further comprising a computer that controls the apparatus operation.

14. The apparatus of claim 13 , further comprising an optical monitor, wherein the optical monitor and the computer are in communication and data from the optical monitor is used to change one or more of the inputs to the reactor.

15. The apparatus of claim 14 , wherein the optical monitor is positioned to measure nanoparticle size.

16. The apparatus of claim 14 , wherein the optical monitor is positioned at the dispenser to measures the chemical composition of the nanocomposite-ink.

17. The apparatus of claim 14 , wherein the optical monitor is positioned at the nanoparticle reservoir to measures the crystallinity of the nanoparticles.

18. The apparatus of claim 14 , wherein the optical monitor is a spectrometer.

19. The apparatus of claim 18 , wherein the optical monitor is positioned at the dispenser to measures spectral absorption of the nanocomposite-ink.

20. The apparatus of claim 13 , wherein the optical monitor includes an electro-magnetic transmitter.

21. The apparatus of claim 1 , wherein the first energy sources or the second energy source is an electro-magnetic source.

22. The apparatus of claim 1 , wherein the second energy sources is a fluidic bath.

23. The apparatus of claim 1 , further comprising a pumping mechanism to inject one or more chemicals into the apparatus.

24. The apparatus of claim 1 , wherein the continuous flow reactor manufactures nanoparticles sized below 70 nm.

25. The apparatus of claim 1 wherein the inside diameter of a channel within the apparatus measures between about 10 microns to about 10,000 microns.

26. The apparatus of claim 25 , wherein a photoactive catalyst is disposed within the one or more of the channels.

27. The apparatus of claim 1 , wherein the nanoparticles are from the group consisting of semiconductors, metal oxides, metal nitrides, metal chalcogenides, fluorides, sulphides, graphene, graphite, ceramics, and metals.
