| 摘要 |
<p>The invention concerns a surfactant formed by at least a particle of nanometric dimensions based on a metal phosphate or vanadate, at the surface of which are bound hydrophobic organic chains, the bonds between said chains and the surface of said particle being non-homogeneously distributed on said surface, such that the thus modified surface particle has an effective amphiphilic character. The invention also concerns emulsifying compositions comprising particles of nanometric dimensions with modified surface which can be surfactants of the type mentioned above, and the method for preparing such emulsifying compositions.</p> |
