Resumen:
Poly(butylene succinate)
(PBS) is one of the most promising biodegradable aliphatic polyester. It is a
semi-crystalline polymer with superior mechanical and thermal properties, high
chemical resistance and lower cost than other biodegradable plastics. Its
processability is similar to that of the polyethylene and its physical
properties are comparable to those of
polyethylene terephthalate. However, blending of polymers is one easy
and effective way to improve its properties. It was also reported the
use of nanoparticles to increase some polymer properties. The
objective is to improve the properties of PBS by the addition of nanocellulose
(CNC). A PEG (polyethylene glycol)/CNC masterbatch was prepared in order to
enhance the dispersion of the nanoparticles. The final ratio of PBS/PEG in the
nanocomposites with 2, 4 and 6 wt.% of CNC, was 80:20 wt.%. The materials were
characterized in order to study the homogeneity of the blends, the
nanocellulose dispersion and the influence of the nanoparticles on their final
properties.
