ABSTRACT

A novel type of biphenyl-bridged alkoxysilane-based crosslinked polyalkoxysilane was prepared by the condensation of 4,4′-bis(triethoxysilyl)−1,1′-biphenyl and different lengths of linear aliphatic diols. Fourier transform infrared spectroscopy, solid-state 13C and 29Si cross-polarization magic angle spinning nuclear magnetic resonance, and thermogravimetric analysis were used to characterize the biphenyl-bridged, crosslinked polyalkoxysilanes. The crosslinked polymers were found to have very quick and high swelling capabilities in organic solvents and oils. The absorption–desorption kinetics and reusability features of the crosslinked polymers were also studied, and we found that the synthesized polymers reached their maximum absorption capacity during a variety of tests without losing capacity. We also tested the absorption performance of the sorbents from water surfaces. All of these results confirm that biphenyl-bridged, crosslinked polyalkoxysilanes could be good candidates as sorbent materials for the cleaning of water from organic contaminants. © 2016 Wiley Periodicals, Inc.
