An ethanol (EtOH) solution of polymerized vinyltrimethoxysilane (VTMS), about 20-mers, was mixed with an aqueous solution of calcium acetate (Ca(OAc)2) and refluxed in N2 for 1 h to give sols of a typical composition VTMS : H2O : EtOH : Ca(OAc)2 = 1 : 9 : 8 : 0.05 (mol). Homogeneous films could be produced, by dip-coating, on Nylon6® and soda-lime glass, but not on polypropylene or polytetrafluoroethylene. The gel films did not deposit apatite within 14 days of soaking in a simulated body fluid whereas films abraded with emery paper as well as bulk gels deposited apatite on the surfaces within 7 days, indicating the present gel was suitable for bioactive coatings on Nylon6®.
