Course unit content

<br />
<br />
The inorganic polymers. Basics of the chemistry of the sol-gel process; the precursors: the chemistry of silicon, chlorides and alkoxides, preparation and pshysico-chemical properties; the definition of sol and gel. The reactions of hydrolisys and condensation.The alcogels. Influence of the reaction parameters on the formation of silicon based inorganic gels. Elctronic and steric effects of the substituents, solvent effect, concentration effect, water-silicon ratio, the catalyst effect, the drying methods. Properties of gels, xerogels and aerogels and their technologic uses.<br />
Characterization techniques for the materials obtained by the sol-gel method: FTIR spectrophotometry, light dispersion thecniques, surface area measurements, solid state NMR, CHNS-O microanalysis, electronic microscopies SEM and TEM.<br />
 <br />
2) The Inorganic-Organic hybrid materials. Classifications and examples. Preparation of the precursors, silicon based hybrid materials obtained by sol-gel method, characterization. Definition of interphase. Polysesquioxanic materials with polyhedric structure. Applications of hybrid materials.<br />
 <br />
3) Use and application of the sol-gel materials in the field of conservation
