To alleviate environmental pollution from plastic wastes, biodegradable polymers have gained considerable attention as an alternative to petroleum-based polymers. Moreover, it exhibits numerous advantages such as light weight, eco-friendliness and good processability. Despite of various properties, the commercialization of biodegradable polymer has been limited owing to their inferior mechanical properties. In the current study, biodegradable nanocomposites consisting of poly(butylene succinate) (PBS) and cellulose nanocrystals (CNC) were fabricated using a solution blending method in dimethyl sulfoxide (DMSO). The rheological responses of the PBS/CNC nanocomposites were explored in terms of the filler amount (0.5-3.0 wt% of CNC) and measurement temperature (160-200 °C). The rheological properties of the nanocomposites at the filler content below 1.0 wt% was reminiscent of that of neat PBS, while the behavior of nanocomposites above the 1.0 wt% was substantially changed. |
