The Design and Investigation of Room Temperature Thermotropic Nematic Gold Nanoparticles

摘要

The controlled spatial assembly of metallic nanoparticles of defined size and shape in organic matrixes has recently received great attention,as such materials promise synergistic property combinations in the self-assembled state.However,to achieve such unique properties,nanoparticles of narrow or ideally uniform size distribution have to be functionalized with suitable organic groups,and these materials have to be organized and oriented.In the area of LC research,the recent observation that the incorporation of "spherical" nanoparticles into nematic liquid crystals (nematic LCs) can enhance the dielectric response and conversely the switching speed significantly is of great technological importance and adds impetus to research into LC nanoparticles.
