Nonmetallic nanoparticles and nanomaterials: Size-dependent behavior of mechanical properties is still not clear in the case of polymer nanomaterials however, in one research by Lahouij they found that the compressive moduli of polystyrene nanoparticles were found to be less than that of the bulk counterparts.
For example, nanoparticles with a distinct chemical surrounding , or specific optical properties. [ citation needed ] Platinum nanoparticles are being considered in the next generation of automotive catalytic converters because the very high surface area of nanoparticles could reduce the amount of platinum required. [ 18 ]
For example, multi-walled carbon nanotubes based polymer nanocomposites have been used for the enhancement of the electrical conductivity. [ 26 ] An alternative route to synthesis of nanocomposites is sequential infiltration synthesis , in which inorganic nanomaterials are grown within polymeric substrates using vapor-phase precursors that ...
Due to the complexity of the equipment, nanomaterials have high cost compared to conventional materials, meaning they are not likely to feature high-volume building materials. [11] In special cases, nanotechnology can help reduce costs for complicated problems. But in most cases, the traditional method for construction remains more cost ...
The most common example is the production of nanocellulose from wood pulp. [39] Other examples are nanolignin, nanochitin, or nanostarches. [40] Nanoparticles with one half hydrophilic and the other half hydrophobic are termed Janus particles and are particularly effective for stabilizing emulsions.
Metallic nanomaterials are commonly made up of transition metals (mostly iron, cobalt, nickel, palladium, platinum). Multi-metal nanomaterials show new properties due to the characteristics of each metal. The advantages are the increase in activity, selectivity and stability and the cost reduction.
Inorganic nanoporous materials are porous materials that include the use of oxide-type, carbon, binary, and pure metal materials. Examples include zeolites, nanoporous alumina, and titania nanotubes. [3] Zeolites are crystalline hydrated tectoaluminosilicates. This material is a combination of alkali/alkali earth metals, alumina, and silica ...
Polymer nanocomposites (PNC) consist of a polymer or copolymer having nanoparticles or nanofillers dispersed in the polymer matrix. These may be of different shape (e.g., platelets, fibers, spheroids), but at least one dimension must be in the range of 1–50 nm. [1]
