In-plane aligned assemblies of 1D-nanoobjects: recent approaches and applications

Abstract

One-dimensional (1D) nanoobjects have strongly anisotropic physical properties which are averaged out and cannot be exploited in disordered systems. We reviewed the in plane alignment approaches and potential applications with perspectives shared.

Ordered polymer composite materials: challenges and opportunities

“…It should be noted that many methods exist which use external fields to organize NPs in other media besides polymers, but this review will focus solely on controlling nanoparticle organization in composites; we direct the reader to other reviews that have covered particle assembly for more information on non-composite structures. [21][22][23][24][25][26][27] The main advantage of using applied fields to control nanoscale organization is that they can be controlled remotely and independently from intrinsic nanomaterial design parameters like particle size or shape. For example, magnetic fields can regulate the alignment of magnetically-responsive nanofillers, [28][29][30] such as paramagnetic nanoparticles, [31][32][33] metal-oxide nanosheets, 34 magnetically active nanofibers, [35][36][37][38] and carbon nanotubes, [39][40][41][42] resulting in the formation of nanofiller arrays with internally organized fillers.…”

Current Trends in Nanomaterials for Metal Oxide-Based Conductometric Gas Sensors: Advantages and Limitations. Part 1: 1D and 2D Nanostructures

“…Moreover, the listed techniques work with an array of 1D nanostructures, and they do not guarantee the fixation of individual 1D structures in the required place. Thus, the use of 1D nanostructures in real devices is still at a preliminary stage and needs a breakthrough in order to integrate them with low-cost industrial processes [149,267,269,273].…”

“…It turned out that for these purposes one can use micro fluidics, electrostatic or magnetic fields, surface pre-pattering, self-assembly, and templating. These approaches, which allowed the design of gas sensor prototypes, were comprehensively considered in [ 219 , 249 , 262 , 263 , 264 , 265 , 266 , 267 , 268 , 269 ]. The advantages and disadvantages of the mentioned above methods of nanowires alignment are briefly summarized in Table 3 .…”

“…The NWs are oriented and transferred to the receiving substrate by applying a directional shear force, resulting in the printing of sub-monolayer parallel NW arrays on the receiving substrate. Reproduced with permission from Hu et al[269]. Copyright 2020: Royal Society of Chemistry.…”

Refined RGB Strategy for the Synthesis of Polymer‐Based Full Organic Luminescent Nanotubes with Broad Emission Bands

“…[15] One-dimensional nanostructures such as wires, rods, belts and tubes have shown great promise as building blocks for bottom-up integrated photonic and optoelectronic devices. [16][17][18][19][20][21][22] In comparison to traditional approaches, nanostructures based on organic molecules are able to provide high luminescence efficiencies for a quite low density or concentration of the material. They are straightforward from an engineering point of view, scalable, cheap in processing, and can be fabricated quickly since a controlled self-assembled growth can be implemented.…”
