Recycled Material

Mechanical recycling is one of the possible ways to enhance the value of postconsumer plastic materials. However, the final performance of the recycled material will strongly depend on the quality of the selection made on the recycled product and on the degradation of the properties. In this context, the present study examines the effect of reprocessing for five successive extrusion cycles on the rheological, mechanical and thermal properties of a poly(butylene adipate-co-terephthalate) (PBAT)-based blend on samples reprocessed in both dry and wet conditions. The results showed that when the sample was processed after drying, degradation of the material was less than when it was processed in wet conditions. However, the experimental results showed that the decrease of rheological and mechanical properties was not so dramatic, and therefore the material could be reused in both cases.

Poly Caprolactone

In this research the polymer electrolyte materials based on poly caprolactone (PCL) has been synthesized and characterized. Polycaprolactone is a non-toxic and biodegradable polymer that is environmentally friendly. The preparation of the polymer electrolyte film is carried out by a casting method whereby the PCL polymer is dissolved in a tetrahydrofuran (THF) solvent. Lithium perchlorate salt (LiClO4) as a source of lithium ions then was added to solution with a composition (5-40)% by weight. The solution was evaporated slowly in vacuum oven until the film was formed. The ionic conductivity, crystal structure, morphology and thermal properties of the polymer electrolyte were characterized by impedance spectroscopy X-ray diffraction (XRD) and Infrared Spectrometer (FTIR, Scanning Electron Microscope (SEM). and Differential Scanning Calorimeter (DSC) respectively. The results of the conductivity measurements showed that the PCL conductivity increased from 3.45 x 10-11 Scm-1 to 5.52 x 10-6 Scm-1 with a 30% weight salt content of LiClO4. Observations with XRD show a more amorphous polymer with more salt addition and FTIR results show that there is interaction between active groups on polymers with salt. The thermal properties show that the melting points of polymer become lower with more salt addition.
