摘要：
Graphene/silver nanoparticle antimicrobial agents were synthesized by chemical reduction, and silver nanoparticles could be loaded onto graphene sheets. Subsequently, the antibacterial polypropylene (PP) composite were prepared via first coating low amounts of PP powder using graphene/silver nanoparticle and then melt-blending the coated PP powders with the PP matrix. The effects of antibacterial agent amounts on the antibacterial performance, mechanical property and discoloration of the antibacterial PP composites were studied. The results show that the antibacterial rate of the antibacterial PP on staphylococcus aureus and Escherichia coli could both each be over 95% with 0.01% graphene/silver nanoparticle antimicrobial agent, and the both antibacterial rates could increase to 99% when the addition dosage is 0.03%. Thus, the graphene/silver nanoparticle antimicrobial agents display excellent antibacterial properties in polymer matrix with lower addition. Meanwhile, the mechanical properties of PP matrix do not be affected by the graphene/silver nanoparticle antimicrobial agents in the case of the above low addition amounts.The tensile strength, flexural modulus and notched charpy impact strength of the samples are maintained at (36.2±0.2) MPa, (1508±15) MPa, (1.79±0.10) kJ/m2, respectively. © 2020, Editorial Board of Polymer Materials Science & Engineering.
