polymetallosilazane for the preparation of nanocomposites a pharmacological decorative, which may be in the form of solid objects

摘要

The present invention relates to a modified polymetallosilazane, characterised in that said polymetallosilazane can be obtained according to a method which includes the following consecutive steps: a) reacting a polysilazane with a molecular entity including at least one transition metal and at least one carbon group in order to obtain a polymer such as a polymetallosilazane, and b) ammonolysis reaction by means of ammonia activity of the polymetallosilazane obtained in order at least partially to eliminate the carbon groups; as well as to a method for preparing a nanocomposite material using such a modified polymetallosilazane and to the resulting nanocomposite materials in the form of a solid object.
