Resumen
Natural rubber (NR) is a renewable polymer with a wide range
of applications, which is constantly tailored, further increasing its utilizations.
The tensile strength is one of its most important properties susceptible of being
enhanced by the simple incorporation of nanofibers. The preparation and
characterization of natural-rubber based nanocomposites reinforced with bacterial
cellulose (BC) and bacterial cellulose coated with polystyrene (BCPS), yielded
high performance materials. The nanocomposites were prepared by a simple and
green process, and characterized by tensile tests, dynamical mechanical analysis
(DMA), scanning electron microscopy (SEM), and swelling experiments. The
effect of the nanofiber content on morphology, static, and dynamic mechanical
properties was also investigated. The results showed an increase in the mechanical
properties, such as Young’s modulus and tensile strength, even with modest
nanofiber loadings.
