Abstract:

The development of polyester based materials with enhanced properties as well as the use of post- consumer plastics as raw material has been an increasing market demand. This work aims the synthesis and characterization of aromatic polyesters/titanium dioxide nanocomposites from PET and using TiO2 (0, 1, 3 and 5% w/w) as filler by in situ polymerization. The results obtained by DSC, XRD and FTIR analyzes evidenced an interaction between the OH groups on the TiO2 surface with the ester groups of the polymer leading to decrease of the polymer crystallinity and of hydrophilicity. By SEM images was possible to note a homogeneous distribution of the filler into polymer matrix with 1%w/w TiO2 (average particle size of 199 nm), however for larger amounts of filler (3 and 5% TiO2) revealed the aggregates formation. The results showed an improvement of thermal properties and hardness of the nanocomposites containing TiO2 nanoparticles compared to pristine polyester
