“…Fig. 4 shows a wide-scan pattern of pristine AgNPs, revealing that the observed peaks can be assigned to face-centered-cubic Ag with a strongly preferred (1 1 1) orientation, in line with JCPDS 4–0783 [37] . The pattern of the PVA/AgNPs/BPTA membrane showed characteristic peaks of the three components.…”

“…The small grain size and large specific surface area of nanocomposites may benefit antibacterial activity [37] , although the exact mechanism of the antibacterial action of AgNPs remains controversial. According to the results of ROS production analysis, the presence of AgNPs did not significantly impact the amount of active oxygen produced by membranes.…”

“…They must also fulfil the essential requirements of enabling rapid hemostasis and have effective antibacterial properties 14 . The antibacterial electrospun nanofibres are usually produced by incorporating antibiotic materials such as ofloxacin 15 , Ag NPs 16,17 or other metallic and metal oxide NPs 18 .…”

Polymer-metal based material with unique 3D structure is an attractive substrate for the development of biomedical applications. A novel preparation of the composite from polymer fibres and silver nanoparticles has been designed through: (1) preparation of silver nanoparticles by phytosynthesis and (2) incorporation of these nanoparticles in a fibrous membrane prepared by electrospinning. The nanoparticle biosynthesis was performed in a pure environmental-friendly, easy, static, bottom-up in vitro regime using Tilia sp. leachate. TEM and XRD depict the formation, stabilisation and encapsulation of crystalline silver (14 ± 9 nm) nanoparticles (NPs) in one simple step with low tendency to aggregate. We achieved successful incorporation in the uniform electrospun 221 ± 24 nm poly(vinylalcohol) fibres, and this confirms the possibility of its use in the biomedical field. Both SEM with EDX and TEM analysis determined fibre uniformity with the presence of silver NPs, and ICP-AES confirmed the relatively similar metal concentration throughout the triplicate measurement of fibre structures on the 2 × 2 cm area in the following manner: 0.303 ± 0.018 wt. %, 0.282 ± 0.017 wt. %, and 0.281 ± 0.017 wt. %. Our hypothesis is based on previously verified preparation of active silver NPs and the easily prepared PVA electrospun fibres which act as a water soluble matrix. The simple methodology of incorporating biosynthetically prepared NPs in the PVA fibers highlights the effectiveness of this material, with simple release from water-soluble PVA and final activation of the prepared NPs.

“…And since this combination consistently yields good physiochemical properties, it is obvious that the ZnO-loaded PVA film composites will be the favoured choice in the future electronics [108][109][110]. Hamza et al [111] have fabricated PVA-Ag and ZnO nanofibers that were exposed to possess enhanced antibacterial properties, which prove its applications in the biomedical fields too. A brief image of the process is shown in figure 12.…”

Nanotechnology has facilitated unique ways of developing novel nano-composites. In that sense, polymer-based nano-composites are being extensively researched for their outstanding properties as a result of incorporating nano-fillers in the polymer matrix. They have activated enormous research interests owing to their potential in addressing environmental issues, packaging, optics, electronics, battery electrolytes, pneumatic actuation, molecular separations, sensors, biomedical applications, etc. Hence, the authors intend to consolidate reported information about these polymer matrices, diverse inorganic nanofillers, and nano-filled polymer composites for improvement in properties and future advanced applications. The review exhaustively covers 15 years of literature on theoretical, experimental, and application aspects of PVA & PMMA-based nano-composites. It also summarizes the structure-property correlations that govern their performance. Hence this review is hoped to provide the readers with stimulating insights on strategies, noteworthy challenges, and future opportunities/prospects in developing polymer nano-composites that may cater to the need of our society and scientific industries as well.
