Abstract:
This work was aimed to study the effect of antimicrobial activity and mechanical properties of natural rubber filled lignin and sodium lignosulfonate (SLS) composites, prepared by sulfur vulcanization and electron beam irradiation (EB). Results from antimicrobial tests of the natural rubber composites prepared by sulfur vulcanized inhibited microbial very well in either Gram positive and negative bacterial growth of Staphylococcus aureus and Escherichia coli, respectively. The natural rubber composites filled with SLS prepared by EB vulcanized, inhibited both Staphylococcus aureus and Escherichia coli. The natural rubber filled with lignin and SLS prepared by EB cannot inhibit both bacteria, neat natural rubber could not inhibit Escherichia coli but could inhibit Staphylococcus aureus at the beginning time (around 3 to 12 h). After that, they could inhibit both bacterial. Tensile strength of the natural rubber composites prepared by sulfur vulcanized improve of the tensile strength when increasing amount of lignin, However, when increasing the amount of SLS, the tensile strength decreased. In the natural rubber composites prepared by EB, it showed lignin improve of the tensile strength as same as that in sulfur vulcanized. Therefore, SLS can improve the tensile strength depending on the amount of SLS.
