Method and apparatus for forming oriented nanowire material and method for forming conductive structure

摘要

The present invention provides a method and an apparatus for forming an oriented nanowire material as well as a method for forming a conductive structure, which can be used to solve the problem of imperfect process for forming oriented nanowire material in prior art. The method for forming an oriented nanowire material of the present invention comprises: forming a liquid film in a closed frame by a dispersion containing nanowires; expanding the closed frame in a first direction so that the liquid film expands in the first direction along with the closed frame; contracting the closed frame in the first direction so that the liquid film contracts in the first direction along with the closed frame; transferring the contracted liquid film to a substrate; and curing the liquid film to form an oriented nanowire material on the substrate.

1. A method for forming a conductive structure, characterized by comprising:
S1: forming a liquid film in a closed frame by a dispersion containing conductive nanowires; S2: expanding the closed frame in a first direction so that the liquid film expands in the first direction along with the closed frame; S3: contracting the closed frame in the first direction so that the liquid film contracts in the first direction along with the closed frame; S4: transferring the liquid film to a substrate; and S5: curing the liquid film to form a first conductive film composed of an oriented conductive nanowire material on the substrate, wherein the size of the liquid film in the direction perpendicular to the first direction is in a range of 10 to 400 mm; the size of the liquid film in the first direction before being expanded is 0.3 mm or less; the size of the liquid film in the first direction after being expanded and before being contracted is in a range of 60 to 1000 mm; and the size of the liquid film in the first direction after being contracted is in a rant of 10 to 300 mm.
