Optical polymer nanocomposites with gold

Dammer et al. [4] also worked with metal nanoparticles and showed the importance of preparation procedure on the optical properties of polymer nanocomposites with gold nanoparticles. Similar to other properties, optical properties depend on the dispersion of nanoparticles caused by the processing conditions. 

Around 1900, widely forgotten reports indicated the preparation of polymer nanocomposites with uniaxially oriented inorganic particles, and their remarkable optical properties (14,15). Dichroic plants and animal fibrils (eg, linen, cotton, spruce, or chitin, amongst others) were prepared by impregnation with solutions of silver nitrate, silver acetate, or gold chloride, followed by reduction of the corresponding metal ions under the action of light (16). 

Polymer-embedded gold nanoparticles have been extensively studied [1]. Because of unique physical characteristics, gold-polymer nanocomposites are potentially useful for a number of advanced functional applications, especially in the optical and photonic fields. In particular, these materials can be used as light-stable color filters [2], polarizers [3, 4], ultra-low refractive index materials [5], nonlinear optical devices [6], optical sensors [7], and so on. However, still limited are the chemical routes that allow us to obtain monodispersed thiol-derivatized gold nanoparticles with controlled size to be embedded into poly-... 

Metal nanopartides can also be cited. The characteristic properties of metal nanopartides and nanocomposites have been the subject of study because of their unique optical properties. Combining metal and polymer together enhances the optical properties of nanometals. Srivastava et al. 3] studied the optical properties of gold nanocomposites by changing the size and fraction of gold nanopartides. The optical properties of nanocomposite films of various thicknesses with different sizes and volume fraction of gold nanopartides have been studied using spectroscopic...
