Abstract
The photelectron spectra of five different liquid silanes were measured. Their C 1s spectra and measured compositions were all consistent with the theoretical formula of these compounds. Subsequently, Eβglass fibers were exposed to dilute aqueous solutions of these silanes, and their adsorption on the fiber surfaces was observed. The highβresolution C 1s spectra revealed the extent of hydrolysis. The thicknesses of the adsorbed layers were determined and were found to scale with the length of the organic functional group.
