Experimental and computational investigation of polylactic acid/silver‐NP nanocomposite with antimicrobial activity prepared by plasma in liquid

Abstract

In this study, an underwater impulse discharge initiated in an aqueous suspension of a polylactide acid between silver rods is applied to produce silver nanoparticles (AgNPs) and create a polymer nanocomposite. The spectral and energy characteristics of the discharge are obtained. The composites are characterized by methods of scanning electron microscopy, transmission electron microscopy, infrared spectroscopy, and thermogravimetric analysis. Investigation of the formation of the composite of polylactic acid (PLA) with AgNP has been performed using the molecular dynamics method. The PLA/AgNPs composite films were effective against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Candida albicans, and thus may find future application in the food packaging area.

Effect of metal oxides added onto polyvinyl alcohol via pulsed underwater plasma on their thermal, electrical and dielectric properties

“…The homemade DC power supply with output voltage up to 10 kV and 0.5 kOhm ballast resistor (R b ) was used to excite the discharge. The details of the experimental setup are described in elsewhere 28 . The scheme of preparing the composites is presented in Figure 1.…”

Applications of plasma synthesized ZnO, TiO2, and Zn/TiOx nanoparticles for making antimicrobial wound‐healing viscose patches

“…We investigated a one‐step method to prepare composite polymer materials containing Ag‐NPs. [ 29 ] The composite material has potent antibacterial activity against Gram‐negative bacteria, Gram‐positive bacteria, and yeasts. Due to the high cost of chemical synthesis of antibiotics and the increasing resistance of bacteria to antibiotics, the replacement of “green chemical” synthesis by NPs with low energy consumption and low cost is an attractive proposal.…”
