Gold dispersion stabilized by tetrathiolated resorcinarenes 1 and 2 and their dispersibility in nonpolar organic solvents. Compound 2 is an exceptionally effective surfactant: it can mediate the extraction of colloidal gold particles as large as 70 nm from aqueous suspensions, and maintain kinetically stable dispersions in nonpolar solvents such as toluene and chloroform. Modified resorcinarenes are excellent dispersants of gold nanoparticles in hydrocarbon solvents, but exhibit variable degrees of robustness.

Gold dispersion metal dispersion are used in a wide range of applications such as catalysis, optical labeling, ferrofluids, and sensing. These applications, along with the recent attention to nanoscale science and technology, fuel the demand for methodologies which enable nanoparticles to be incorporated into nanostructured devices and composite materials. Dispersing metal particles in nonpolar organic solvents is appealing because the low interfacial energies should allow for a high degree of control during solution and surface processing. Unbranched  alkanethiols and carboxylic acids have been used to stabilizedispersionsofsmall(<10nm)metalnanoparticles in organic solvents, but encapsulated particles.

Gold dispersion The color of colloidal dispersions of gold particles in a fluid, typically water, varies from red to blue, depending upon the shape and size of particles. The color and optical properties of Gold nanoparticles dispersion originate from localized surface plasmons, and are sensitive to their local dielectric environment. Unlike nanospheres, the optical properties, hydrodynamic behavior as well as phase behavior of nanorods are influenced by their shape anisotropy. Thus absorption peak, possess very different dynamics (affects sedimentation) and their concentrated dispersions form liquid crystalline phases. The essential shape dependent optics, as well as the hydrodynamics and phase behavior of rod-like gold nanoparticles.

Gold dispersion Nano-composites are one of the most attractive part of the composite materials. Due to the fast development in recent years, composites are put in an important position by the developed countries in the development of new materials. The research on nano-composites includes organic-inorganic composites, nano-polymer matrix composites and inorganic-inorganic composites. In this chapter, combined with our research experience, we mainly introduce the nano-polymer matrix composites to the readers.
