Polyvinylpyrrolidone k product series

Name :Polyvinylpyrrolidone k30
CAS NO.:9003-39-8
Molecular formula (C6H9NO)n
Appearance shape:
White or milky powder
Main properties:
Excellent dispersion and stability for nanomaterials

Main application examples
In the preparation of silver nanoparticles, as a dispersant, it can be adsorbed on the surface of silver particles to prevent the agglomeration of silver particles, thus controlling the particle size of silver nanoparticles. In the use of silver nanoparticles, due to the small particle size, large specific surface area and high surface energy, silver nanoparticles are prone to agglomeration in dry environment, thus affecting the physical properties and functions of silver nanoparticles. The use of PVP ensures good dispersion.
