Nanowet

How a “nanowet” workshop works?

Starting from chemical precursors, a colloidal synthesis enables you to obtain nanoparticles. After characterization, they are either directly integrated in a matrix, or chemically processed (functionalization, encapsulation) in order to insert them in the matrix. A disaggregation and then dispersion of nanopowders in liquid route can also lead to a "nano" colloid. In each phase of activity: Transport, Processing, Maintenance, Storage, and Management of solid and liquid wastes, the particle propensity to disperse will be specific.

Transfer after cooling.

Colloidal synthesis consists in causing one or more chemical species to react, with a view to obtaining a material whose composition and dimension are controlled in colloidal suspension within the elaboration medium. The operating conditions and the composition of the reaction medium enable, in particular, the size (< 100 nm) and geometry (spheres, rods, etc.) of the particles formed to be controlled. Post-synthesis treatments may be required, notably in order to improve the purity of the colloidal solution formed: rinsing/centrifugation or nanofiltration for example, to separate the nanoparticles from the reaction medium that has not reacted.
