Method for fabrication of 2D net-like patterns of nanoparticles on solid substrates and surface covered by this method
- Summary:
The invention comprises the method of covering a solid surface with a two-dimensional network of nanoparticles, wherein the mixture of the nanoparticle solution and a liquid crystalline (LC) compound is drop-casted onto the water surface, and subsequently the obtained film is transferred onto a solid surface using the Langmuir-Blodgett method. It is characteristic that the LC compound belongs to the group of cyanobiphenyls. The invention also includes the solid surface covered with such a 2D nanoparticle network.

- Advantages / Innovative aspects:
- The method allows for fabrication of a two-dimensional network of metallic nanoparticles stabilized with an organic ligand;
- Such a network is formed on the water Surface and can be transferred to a solid substrate, where it remains stable over time;
- By proper adjustment of the nanoparticle/LC mixture and surface pressure during the compression of the film on the water surface, it is possible to precisely control the mesh size of the resulting network
- Analogous networks can be fabricated with no compression, providing that proper mixture composition is kept and the incubation period is long enough
