Resumo
The aim of this research was to check the changes in the mechanical and thermal properties of poly(butylene
adipate co-terephthalate)/poly(lactic acid) (PBAT/PLA) polymeric blend, which commercial name is Ecovio®,
after radiation processing in different absorbed doses. PBAT and PLA are biodegradable polymers and the
Ecovio® polymeric blend consists of at least 80% of polymers from renewable resources. The irradiation was
performed in a Radiation Dynamics Inc. electron beam accelerator, with 1.5 MeV of energy and electric current
of 25 mA. Samples were prepared for micrograph, mechanical and thermal analyses. These samples were
irradiated with absorbed doses of 5 kGy, 10 kGy, 15 kGy, 25 kGy and 50 kGy. The samples, after irradiation,
were submitted to experiments of ultimate strength, tensile strength, ultimate elongation, differential scanning
calorimetry (DSC) and scanning electron microscopy (SEM). The results showed a good interaction between the
components of the polymeric blends and the radiation effect on polymeric blend promoted changes in PBAT and
PLA polymers, increasing tenacity of these biopolymers and consequently facilitating yarn formation in
processing. In conclusion, these irradiated blends could be used to make environmental friendly products.
