Abstract
Methods and systems for depositing nanomaterials onto a receiving substrate and optionally for depositing those materials in a desired orientation, that comprise providing nanomaterials on a transfer substrate and contacting the nanomaterials with an adherent material disposed upon a surface or portions of a surface of a receiving substrate. Orientation is optionally provided by moving the transfer and receiving substrates relative to each other during the transfer process.
Claims30
A method of depositing nanomaterials onto a substrate, comprising:
- providing a plurality of nanostructures disposed upon a transfer substrate wherein the transfer substrate is disposed on a roll;
- providing an adherent material deposited on one or more selected regions of a receiving substrate;
- mating the transfer substrate with the receiving substrate whereupon the nanostructures contact the nanostructures on the transfer substrate with the one or more selected regions of the receiving substrate;
- and
- separating the transfer substrate from the receiving substrate to leave a population of nanostructures adhered to the one or more selected regions of the receiving substrate.
A method of depositing nanomaterials onto a substrate, comprising:
- providing a plurality of nanostructures disposed upon a transfer substrate;
- providing an adherent material deposited on one or more selected regions of a receiving substrate;
- mating the transfer substrate with the receiving substrate;
- and
- separating the transfer substrate from the receiving substrate to leave a population of nanostructures adhered to the one or more selected regions of the receiving substrate;
- wherein between the mating step and the separating step, at least one of the transfer substrate and the receiving substrate are moved in a direction substantially parallel relative to the other of the transfer substrate and the receiving substrate, to substantially align the nanostructures adhered to the receiving substrate.
A method of depositing a plurality of substantially oriented nanostructures on a substrate, comprising:
- providing a transfer substrate having a plurality of nanostructures deposited thereon, each of the plurality of nanostructures having a major axis;
- providing a receiving substrate having a surface comprising an adherent material;
- bringing the nanostructures on the surface of the transfer substrate into contact with the adherent material on the surface of the receiving substrate whereupon the nanostructures adhere to the adherent material;
- moving one or more of the transfer substrate and receiving substrate relative to the other of the transfer substrate and the receiving substrate to substantially orient the nanostructures along a common axis;
- and
- separating the nanostructures from the transfer substrate after the moving step, to leave the plurality of nanostructures substantially oriented on the receiving substrate along the common axis.
