PLA en PE: Visco-elasticiteit en degradatie

Researchers at Chuka University in Kenya compared the viscoelastic properties of commercially obtained PLA and PE films, and the degradation of the same under a composting environment. The elastic modulus of PLA was found to be higher than that of PE at 50˚C and amplitude of 10 μm.
Analysis of composting samples over a time span of 36 days indicated a rapid loss of storage modulus of PLA with that of PE remaining fairly constant. Overall, the results suggest that PLA is a suitable substitute for PE in as far as technical performance and degradability is concerned. An article about the research is published in the International Journal of Physical Sciences.
