“…In general, metal-based antiviral surfaces can be grouped in two classes. The first class includes ‘pure’ metal surfaces, including entirely metallic products, whereas the second class includes products with metalized surfaces or coatings composed of metallic nanoparticles, often embedded in polymer matrix [31] , [32] , [33] , [34] , [35] .…”

“…In the TEM images in Figure 2 , the Ag NPs were of spherical shape ( Figure 2 a,d) and Ag NPrsms of sharp triangular shape ( Figure 2 b,f). The size of the Ag NPs was 20–40 nm, which was a good size for Ag NPs in biomedical and thermal therapy applications [ 13 , 24 , 25 ]. The Ag NPrsms appeared to be larger, at approximately 60 nm (TEM images in Figure 2 b).…”

“…One absorption peak around 256 nm derived from GO, and the other at 405 nm from Ag NPs. These absorption wavelengths of Ag NPs and GO–Ag NPs are in the range of those of Ag composites prepared via in situ reduction method [ 24 ]. The GO–Ag NPrsms demonstrated a dark blue color and had two absorption peaks: one from GO at 250 nm, and the other shoulder at 600–700 nm.…”

Spherical silver nanoparticles (Ag NPs) and silver nanoprisms (Ag NPrsms) were synthesized and decorated on graphene oxide (GO) nanosheets. The Ag contents were 29% and 23% in the GO–Ag NPs and GO–Ag NPrsms, respectively. The Ag NPrsms exhibited stronger (111) crystal signal than Ag NPs. The GO–Ag NPrsms exhibited higher Ag (I) content (75.6%) than GO-Ag NPs (69.9%). Increasing the nanomaterial concentration from 25 to 100 µg mL−1 improved the bactericidal efficiency, and the antibacterial potency was in the order: GO–Ag NPrsms > GO–Ag NPs > Ag NPrsms > Ag NPs > GO. Gram-positive Staphylococcus aureus (S. aureus) was more vulnerable than Gram-negative Escherichia coli (E. coli) upon exposure to these nanomaterials. The GO–Ag NPrsms demonstrated a complete (100%) bactericidal effect against S. aureus at a concentration of 100 µg mL−1. The GO–Ag composites outperformed those of Ag or GO due to the synergistic effect of bacteriostatic Ag particles and GO affinity toward bacteria. The levels of reactive oxygen species produced in the bacteria–nanomaterial mixtures were highly correlated to the antibacterial efficacy values. The GO–Ag NPrsms are promising as bactericidal agents to suppress biofilm formation and inhibit bacterial infection.

“…There is a drawback concerning this type of reinforced polymeric material. Sometimes, there is no good compatibility between the polymer and the reinforcement, thus reducing the material properties to be obtained [ 108 , 109 , 110 ]. The use of additives to improve material properties for processing and application is common practice in sheet molding compounds for traditional injection molding applications [ 111 , 112 ].…”

Innovation in Additive Manufacturing Using Polymers: A Survey on the Technological and Material Developments

et al. 2022

This review summarizes the most recent advances from technological and physico-chemical perspectives to improve several remaining issues in polymeric materials’ additive manufacturing (AM). Without a doubt, AM is experimenting with significant progress due to technological innovations that are currently advancing. In this context, the state-of-the-art considers both research areas as working separately and contributing to developing the different AM technologies. First, AM techniques’ advantages and current limitations are analyzed and discussed. A detailed overview of the efforts made to improve the two most extensively employed techniques, i.e., material extrusion and VAT-photopolymerization, is presented. Aspects such as the part size, the possibility of producing parts in a continuous process, the improvement of the fabrication time, the reduction of the use of supports, and the fabrication of components using more than one material are analyzed. The last part of this review complements these technological advances with a general overview of the innovations made from a material perspective. The use of reinforced polymers, the preparation of adapted high-temperature materials, or even the fabrication of metallic and ceramic parts using polymers as supports are considered. Finally, the use of smart materials that enable the fabrication of shape-changing 3D objects and sustainable materials will also be explored.
