Wettability of a glass surface modified with chemically adsorbed monolayers containing a poly(ethylene oxide) chain

Abstract

For the purpose of developing antifogging thin films which excel in transparency, chemically adsorbed monolayers containing poly(ethylene oxide) chains have been prepared on a glass surface by two methods, i.e., the reaction of poly (ethylene glycol) with a chemically adsorbed chlorosilane derivative and the direct reaction of poly(ethylene glycol) with silanol groups on a glass surface. The former method was found to produce a high density monolayer having the poly(ethylene oxide) chain. The glass modified with the monolayer was superior in wettability to the unmodified glass washed and stored for several days.
