Best Nanoparticles Dispersion Methods And It's Effects

Nanoparticles Dispersion | Image Resource : hwnanomaterial.com

Nanoparticles are dispersed in a solvent to enhance its solubility and to make them into homogeneous solutions. These homogeneous solutions are used in various industries for the manufacture of drugs, building materials etc. Dispersion methods play an important role in exhibiting the chemical properties of nanoparticles. Hence dispersion methods are an uncompromisable process to bring the nanoparticles fully into its function.

Some best nanoparticle dispersion methods:-

Normal dissolutions

An equimolar mixture of solvents that are both organic and inorganic in nature is mixed with accurately measured weighted nanoparticles. There are some variations seen in this practical approach. Yes, differing the ratio between solvent and nanoparticles results in the production of a new solution that is different in both physical and chemical properties. This is one of the simplest nanoparticle dispersion methods available in practice.

Ball milling

If you need the nanoparticles in dry form, you could follow this ball milling technique. This method is suitable only for dispersion of nanoparticles in the solid phase. Dry nanoparticles that are obtained in crystal form are ball milled and grained to particles that are nano in dimension. Sometimes, and mordant in solid phase can be added to increase or decrease the affinity between the particles. This dispersion method is widely prevalent in synthesizing dry nanoparticle dispersion methods.

Electrostatic stabilization

Exploiting the zeta potential, and precipitating the particles that are potentially different from other substance. This method of dispersion involves the principles of electrochemistry and surface chemistry.It is not that difficult to achieve stability in case of electrostatic stabilization, due to the fact that, zeta potential is a surface phenomenon rather than being thermodynamic in nature.

Sonication

Irradiating the agglomerates with a high intense field with ultraviolet or infrared radiation results in fragmentation and yield nanoparticles. The addition of stabilizing agents can be avoided as a stabilizing agent is inactivated at high temperatures. This process faces a drawback of being highly sensitive to temperature changes. Exact temperature or temperature range should be mounted, so that the dispersion process produces nanoparticles that are even in terms of their compositions.

Dispersion methods effects on nanoparticle properties:-

The presence of substances like interferons and other biological agents reduce the viability of nanoparticles thereby inducing a temporary instability among the dispersed medium.

The introduction of froth floating agents should be monitored carefully so that the chances of action between various contaminants are inhibited at initial stages itself.
