Nylon‐6 substrates were coated with SiO 2 ‐RSiO 3/2 (R = methyl, vinyl, phenyl) thin films by the sol‐gel method, and their water permeability was evaluated Tetraethoxysilane (TEOS) and trifunctional alkoxides such as methyltriethoxysilane (MTES), vinyltriethoxysilane (VTES), and phenyltriethoxysilane (PhTES) were used as starting materials. Water permeability coefficients of the nylon‐6 substrates coated with these SiO 2 ‐RSiO 3/2 thin films were increased with an increase in the content of these trialkoxysilanes in the films. The water permeability coefficients of these coated nylon‐6 substrates were smaller in the order of the systems TEOS‐PhTES < TEOS‐VTES < TEOS‐MTES in the relatively low content of the trialkoxysilanes. © 1996 John Wiley & Sons, Inc.
