PLA and PE: Viscoelastic properties and degradation

08 January 2016

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.
