Abstract

A method for producing an electrocompacted and aligned strand is disclosed. The method includes the steps of: providing a channel having an anode on one side and a cathode on the other side separated by a non-conductive material to form an electrode; dispensing a solution comprising one or more electrocompactable and alignable molecules, nanoparticles or microparticles with ampholytic nature into the channel to complete a circuit between the anode and the cathode; applying a DC current in the range of 1-200 volts to the electrode through the solution in the channel to form an electrocompacted and aligned strand; and transferring the aligned strand out of the electrode. The one or more electrocompactable and alignable molecules, nanoparticles or microparticles with ampholytic nature can comprise collagen molecules that have different charges at different pH values. Materials including electrochemically aligned and compacted compounds are also disclosed.

Claims (24)

1. A method for producing an electrocompacted and aligned strand comprising the steps of:

providing a channel having an anode on one side and a cathode on the other side separated by a non-conductive material to form an electrode;

dispensing a solution comprising one or more electrocompactable and alignable molecules, nanoparticles or microparticles with ampholytic nature into the channel to complete a circuit between the anode and the cathode;

applying a DC current in the range of 1-200 volts to the electrode through the solution in the channel to form the electrocompacted and aligned strand; and

transferring the aligned strand out of the electrode.

2. The method according to claim 1 , further comprising a conductive layer that includes the anode and the cathode.

3. The method according to claim 2 , wherein the non-conductive material comprises a non-conductive layer.

4. The method according to claim 3 , wherein the electrode has stacked layers comprising the conductive layer and the non-conductive layer.

5. The method according to claim 3 , wherein the channel comprises a groove formed within the conductive layer to separate the anode from the cathode above the non-conductive layer, wherein the groove has a width between 0.05-10 mm.

6. The method according to claim 1 , wherein the dispensing step includes dispensing a solution from a reservoir system to a location on the channel.

7. The method according to claim 6 , wherein the transferring step includes transferring the aligned strand out of a position of the electrode to a collection device.

8. The method according to claim 7 , wherein the collection device is located downstream from the reservoir system.

9. The method according to claim 8 , wherein following the transferring step, the method further includes the step of dispensing additional solution to the position of the electrode where the aligned stand was transferred for continuously producing aligned strands.

10. The method according to claim 7 , wherein the collection device includes an extraction spool, and wherein the transferring step comprises transferring the aligned strand with the extraction spool.

11. The method according to claim 6 , wherein the transferring step includes determining an angle of separation of the aligned strand being removed from the electrode to maintain constant tension on the aligned strand.

12. The method according to claim 11 , wherein the transferring step includes using the determined angle of separation for synchronizing the rotational speed of the extraction spool.

13. The method according to claim 12 , wherein the transferring step includes directing the aligned strand with the extraction spool from the channel to a bath.

14. The method according to claim 13 , wherein the bath contains a treatment solution selected from the group consisting of water, PBS, ethanol, isopropanol, acetone, chloroform, and mixtures thereof.

15. The method according to claim 1 , wherein the one or more electrocompactable and alignable molecules, nanoparticles or microparticles with ampholytic nature comprise collagen molecules.

16. The method according to claim 15 , further comprising a conductive layer that includes the anode and the cathode, and wherein the non-conductive material comprises a non-conductive layer.

17. The method according to claim 15 , wherein the channel comprises a groove formed within the conductive layer to separate the anode from the cathode above the non-conductive layer, wherein the groove has a width between 0.05-10 mm.

18. The method according to claim 15 , wherein the dispensing step includes dispensing the solution from a reservoir system to a location on the channel.

19. The method according to claim 18 , wherein the transferring step includes transferring the aligned strand out of a position of the electrode to a collection device.

20. The method according to claim 18 , wherein the transferring step includes determining an angle of separation of the aligned strand being removed from the electrode to maintain constant tension on the aligned strand.
