PROCESS FOR THE PREPARATION OF NANOPARTICLES |
abstract |
The present invention relates to a new process for the preparation of nanoparticles with a diameter of less than or equal to 500 nm, comprising the placing in the presence of a solution (1) comprising nanoparticles of a first polyelectrolyte in the charged state, bearing lateral groupings hydrophobic, with (2) at least a second polyelectrolyte of opposite polarity to that of the first polyelectrolyte, characterized in that the ratio Z of the number of cationic groups relative to the number of anionic groups in the mixture of the two polyelectrolytes is between 0, 1 and 0.75 or between 1.3 and 2; and the total mass concentration C of polyelectrolytes is strictly less than 2 mg / g of the mixture. |
