Synthetic polymers are important industrial materials, but their everyday use is
hazardous to the environment. The solution to this seems to lie in modification of their
structure through blending with biopolymers. Low density polyethylene (LDPE) and
Cellulose were used in sample preparation for research in this work. LDPE/starch
composites have undesirable properties and so there was need to explore LDPE/cellulose
composites and evaluate their susceptibility to primary biodegradation. Compression
molded composites were subjected to primary degradation in Aspergillus niger culture
for 60 days. Creep measurements were performed at 30, 40, 50 and 60 oC. The sample
was displaced for 12 minutes and allowed to recover for another 12 minutes. Creep
performance of the samples improved with cellulose loading. Time temperature
superposition was used to predict the long time (up to 106 s) creep behavior of the
samples. William-Landel Ferry model was obeyed by the shift factors, so, the
deformation was dependent on free volume. Creep performance of the samples
deteriorated on inoculation. |
