<p>The present invention relates to a new synthesis procedure for a family of silica based polymer materials synthesized through the interconnection of silicate oligomers with reactive silanes. By using this synthesis it is possible to generate novel silica based polymer materials. The present invention thus also relates to the members of this group of ordered silica based polymer materials whereby silicate oligomers are interconnected trough siloxane bridges and with empirical formulae Abx, whereby A presents the silicate oligomer, b the siloxane bridge and x the ratio between the number of silanes and the number of silicate oligomers in the material. This group of materials are particularly useful for certain applications. In another aspect, the present invention provides the use of the materials of present invention as a fire retardant coating, to enforce polymers, as a cross linking agent in polymers, as adsorbent in water purification, in separation processes, as catalyst or catalyst support in catalysis, for spin-coating of thin films, for spin-coating of thin films with low k dielectric layers in integrated circuit applications, in sensors, as (super)hydrophobic anti-ice coating on airplanes and windmills, as anti-fouling coating inside for instance in pipelines, as anti-dirt coating.</p> |
