Antimicrobial, Conductive, and Mechanical Properties of AgCB/PBS Composite System

Abstract

Demand for environmentally friendly plastic materials which are obtained from renewable resources such as biomass-based polyesters is of concern. Herein, the enhanced characteristic performances of poly(butylene succinate) (PBS) by employing the fabrication of PBS-based composites with the nanosilver-coated carbon black (AgCB) using an injection-molding method are reported. The preformed AgCB additives are priorly prepared by the benzoxazine oxidation method. Phase characterization of the obtained composite materials examined by X-ray diffraction (XRD) reveals the crystalline PBS matrix and the presence of metallic silver particles, confirming the successful fabrication of the composite materials. Detailed analyses on thermal, mechanical, electrical, and antimicrobial properties of the composite materials are reported. The AgCB-PBS composite materials provide such potential features by an enhancement of electrical conductivity and the antimicrobial activity by an inhibition against E. coli and C. albicans. These AgCB-PBS composite materials show the possibility to be an option for antielectrostatic and antimicrobial applications such as for the production of smart, environmentally friendly keyboards.

Effect of Silver Nanopowder on Mechanical, Thermal and Antimicrobial Properties of Kenaf/HDPE Composites

“…Based on Tables 3 and 4, the kenaf/HDPE composites with AgNPs revealed a stronger activity against the gram-negative bacteria compared without AgNP composition, which is significantly lower than the activity seen in the earlier literature [5,48]. Antimicrobial variation may be attributable to their different configurations of cell walls [42,49]. According to Priyadarshini et.al.…”

“…Consequently, the thin layer of peptidoglycan allows the penetration of silver nanoparticles in microbial to destroy. Additional microorganisms, specifically the pathogenic fungus C. albicans, were also tested, and the processed kenaf/HDPE composites filled with AgNPs exhibited greater areas of inhibition compared to Gram-negative bacteria, which followed the work of Veranitisagul et al [49]. Once again, the process is specifically connected to the microorganisms' cell wall structure.…”

Thermoplastic elastomers containing antimicrobial and antiviral additives for mobility applications

“…Veranitisagul investigated antimicrobial, conductive, and mechanical properties of poly(butylene succinate) (PBS) by employing the fabrication of PBS-based compounds with the nanosilver-coated carbon black (AgCB) using an injection molding. Tensile strength, elongation at break, impact strength, and bending strength are slightly decreased with the addition of AgCB in comparison with the pristine PBS materials [ 23 ]. On the other hand, Silva et al studied the effects of the size, modification, and amount of nanoparticles on the thermal, mechanical, and antimicrobial properties of low-density polyethylene (LDPE)/calcium oxide (CaO) and LDPE/mod-CaO.…”

Effect of nano‐silver coated carbon black on curing, mechanical, antimicrobial, and electrical properties of natural rubber composite

“…This simple and effective method can be carried out at room temperature in various organic solvent media and requires only a few minutes. Using this technique, the prepared nano‐silver coated carbon black was applied as an additive for polylactic acid (PLA) and polybutylene succinate (PBS) to increase the antimicrobial properties and electrical conductivity of composite materials 8,9 . However, serious concerns have been raised about the toxicity and hazardous nature of the chemical reagents used in the synthesis of silver nanoparticles.…”
