Surface properties of nanosized silica, synthesized using fluoridation technologies, have been modified by direct fluorination using F2-gas or by plasma radio frequency. The modifications of the physicochemical characteristics of the surface have been characterized by spectrometry of photoelectrons (XPS), infrared and high resolution transmission electronic microscopy and compared with those of pristine silica.
