Sol–gel precursors of poly[bis(methoxyethoxyethoxy)phosphazene] have been synthesized by incorporating triethoxysilane in the polymer side groups. Studies of the water-swelling (see Figure, dry left, water-swollen, right) behavior and dye-release of the hybrid network indicate that the polyphosphazene–silicate network has potential as a biomaterial and for use in both passive and responsive membranes.
