Carbon nanotubes (CNTs) has been reported for nearly 30 years, but commercial applications is rarely reported. Some reasons for this are related to the CNT properties, especially the electronic properties. Approximately 67% of semiconducting CNTs and 33% of metallic CNTs is usually achieved via a normal synthesis. However, it is difficult to implement a large-scale, ordered assembly of the CNTs. Currently, there are two mainstream methods for obtaining CNTs arrays. Although great progress has been made with direct growth methods using special techniques, there is still room to simultaneously increase both the density and purity. With the development of purification technology, solution assembly methods has attracted tremendous attention because of their ease of processability, low cost of fabrication, and ability to cover large areas at room temperature. In this review, we highlight solution assembly methods and divide the existing methods into three categories. In each category, we give a detailed description of the specific method including the mechanism, an illustration of the process, achievements, advantages, and disadvantages. Finally, the development trends and the research frontier according to our own understanding is described. In this review, a valuable reference for scholars engaged in related research is provided.

“…The printing was accomplished by developing conductive inks composed of silver nanoparticles, and silver and copper salt solutions with self‐reduction ability. It should be noted that in contrast to a previous paper, this method does not require any wet cleaning step for increasing the resolution.…”

“…The surfaces can have different levels of hydrophilicity or even complex prepatterned structures with a variety of materials can be used . Furthermore, the structure of the nanopen as described below, has a highly exposed probe tip that is easily visible from above, allowing for ease of placement accuracy with the highest resolutions of the optical microscope . In this study, we report on the application of fountain pen nanolithography for printing conductors with micrometer and nanometer scale line widths.…”

The field of printed electronics is continually trying to reduce the dimensions of the electrical components. Here, a method of printing metallic lines with widths as small as 15 nm and up to a few micrometers using fountain pen nanolithography (FPN) is shown. The FPN technique is based on a bent nanopipette with atomic force feedback that acts similar to a nanopen. The geometry of the nanopen allows for rapid placement accuracy of the printing tip, on any desired location, with the highest of optical sub‐micrometer resolution. Using this nanopen, investigations of various inks are undertaken together with instrumental and script‐tool development that allows accurate printing of multiple layers. This has led to the printing of conductive lines using inks composed of silver nanoparticles and salt solutions of silver and copper. In addition, it is shown that the method can be applied to substrates of various materials with minimal effect on the dimension of the line. The line widths are varied by using nanopens with different orifices or by tailoring the wetting properties of the ink on the substrate. Metallic interconnections of conducting lines are reported.
