Synthesis of layered silicate-organic nanohybrids by immobilization of ethylene oxide chains onto layer surface.

Abstract

Silylating agents containing ethylene oxide groups were synthesized by the reaction of polyethylene glycol monomethyl ethers with methyltrichlorosilane. The silylating agents react with layered silicate octosilicate to immobilize ethylene oxide groups onto interlayer surface. The regular grafting of ethylene oxide groups (MW = 550) was confirmed by XRD patterns and ²⁹Si MAS NMR spectra.
