We investigated the growth of TiO 2 on poly((tetrahydropyran‐2‐yl N ‐(2‐methacryloxyethyl) carbamate)‐ co ‐(methyl 4‐(3‐methacryloyloxypropoxy) cinnamate) (THP‐polymer) using thermal heating, octyl isocyanate (OIC), and glutaraldehyde. It is found that TiO 2 can be grown on surfaces terminated with NH 2 and O groups from aqueous solution. However, TiO 2 did not deposit on CH 3 terminated surfaces, due to the low surface energy of these surfaces. Fourier transform infrared spectroscopy and thermogravimetric analysis data showed that the THP functional group can be removed and the surface functional group converted to NH 2 by heating the material over 180°C. OIC can then be immobilized on the surface after heating, changing the surface functional group from NH 2 to CH 3 . As TiO 2 can be deposited from solution on NH 2 terminated, but not CH 3 terminated surfaces, THP‐polymer can be used to switch the surface properties by thermal activation and subsequent reaction with OIC. © 2011 Wiley Periodicals, Inc.
