Abstract

This project aims the synthesis and characterization of amphiphilic polyesters inspired by the structure and self-assembly of phospholipids molecules. These polyesters based on renewable raw-materials and presenting dihydrogen phosphate pendent groups will be synthesized by polycondensation of glycerol monophosphate and dicarboxylics acids with different numbers of methylene groups (sebacic acid, dodecanedioic acid and hexadecanedioic acid). Different catalyst, such as organometallics, enzymatics and inorganic acids, will be used and the polymers structure and properties will be correlated with the polycondensation conditions. The characterization of these polymers will be performed in relation with their composition, structure, morphology and degradation (hydrolytic and enzymatic), besides their thermal and mechanical properties will be also evaluated. Due the specificity of the designed architecture of these polymers inspired by phospholipids, which present long methylene segment of the dicarboxylic acids, the ability of self-assembly is expected. Therefore, the study of the self-assembly in solid and in solution will be studied. These polymers can find applications as materials for biomedical application, flame-retardant materials, electrolytic membranes and materials to complex with metal ions, for instance. (AU)
