Note: The coating or stabilizing agent of the nanoparticles produced due to their special surface area and high surface energy, adhere together and form a mass. This phenomenon results in the loss of properties due to the small size of these particles.
Stabilizers are used to prevent the accumulation of nanoparticles during the synthesis phase. Typically, two types of electrostatic and spatial drift methods are used to stabilize the nanoparticles. In the first method, ions are used to stabilize the nanoparticles. These ions are attracted to the particles and form an electrically charged layer around the nanoparticles, resulting in the Raman covalent drift of the particles. In the second method, the molecules are used to stabilize the nanoparticles. The coarser molecules stick to the surface of the particles and occupy space around the nanoparticles. As the particles approach each other, these molecules clump together and Raman collapses. The interfacial interactions of nano-fat as a function of nanoparticle structure, surface morphology and electrochemistry. This broad target consists of a number of nanomolecules derived from coarse-grained molecular simulations.
In the production of porous nanoparticles by coating resuscitation or stabilization of nanoparticles, sputter drift is usually employed to stabilize the particles. The stabilizers have been used in this method to mix the two stabilizers needed as the stabilizing agent. Most commonly used in nanoparticle coatings. Based on the synthesis of nanoparticles, the resuscitation agent has been stabilized with the size of the nanoparticles. One of the most influential parameters on the size of nanoparticle synthesis is that the higher the monitoring material concentration and the higher the precursor concentration, the larger the particle size produced, and the smaller the monitoring material concentration , the smaller the particle size. Different concentrations of production and the impact of the monitoring concentration of the material are related to the size of the nanoparticles produced. By changing the concentration of nanoparticles to Nm decreased. In the synthesis of nanoparticles and the increase in the size of the particles produced increases from nanometer to micro.
Conclusion
The effect of the amount of monitoring material on the synthesis of silver nanoparticles has been increased, which has increased to the resulting particles by increasing the average value of nanometer- sized particles . Synthesized nanoparticles at different concentrations that do not change with increasing concentration of the monitoring material are nanoparticles identified and the resulting nanoparticles are spherical. But as the average monitoring value increases, the particle size increases from nanometer to micro . On the other hand, as the concentration of precursor increases, the size of the resulting nanoparticles increases with increasing volume.
