To provide the student with an observative approach to the preparation of materials in order to correlate the properties with the preparation method
Course contents summary
1) preparation of silica xerogels in different reaction conditions. Correlations between macroscopic properties and the structure of t he obtained materials.
2) preparation by sol-gel method of hybrid materials containing mono- bi and tri-dentate amines. Use of the xerogels as metal absorbants for acqueous solutions. Coordination chemistry on a supported phase.
3) Practical experiments of FTIR spectrophotometry: acquisition of spectra by trasmission techniques, (KBr pellet, nujol, solution), HATR (ZnSe and diamond crystals) and microspectrophotometry.
4) Preparation of glass fibers by sol gel method.
