“…It seems that the presence of AgNP attached to the MWNT surface have reduced van der Waals forces and prevented agglomeration amongst the nanotubes. This is in good agreement with a study showed by Xin and Li [36]. The significant increment in the conductivity and dielectric permittivity of the nanocomposites are ascribed to high physical interactions between polymer chains and the conductive networks of MWNT-AgNP.…”

This paper is about tailoring high permittivity of multi-walled carbon nanotubes/silver nanoparticles (MWNT-AgNP) filled polyvinyl alcohol (PVA) nanocomposites at low frequency. PVA/MWNTAgNP nanocomposites were synthesized via solution-casting technique at low MWNT content with different loading of AgNP. The nanocomposites showed a significant increment in ac conductivity, σ ac , and dielectric permittivity, ε′ by two orders of magnitude as compared to pure PVA. The maximum ε′ value was achieved about 600 at 1.0 wt% of AgNP due to the increased charge carriers density and high interfacial polarization within the nanocomposites. The relaxation frequency was shifted towards a higher value with the increased of AgNP content while the relaxation time was decreased by 40%. Field emission scanning electron microscopy (FESEM) images showed the enhanced distribution of MWNT in the presence of AgNP to provide conductive pathways in the matrix. This was confirmed by energy-dispersive x-ray (EDX) analysis and ultraviolet-visible (UV-vis) spectroscopy. As a result, PVA/MWNT-AgNP nanocomposites have great potential for electrical applications such as cable accessories, high charge-storage capacitor and electromagnetic interference shielding materials.

“…The increased concentration of nanoparticles resulted in an increase of the adhesive's breaking strength, which supported previous research findings that increased mechanical strength were due to the dispersion of more nanoparticles to interact with the polymer matrix [31,59].…”

“…On average, the adhesive strength of the adhesives containing 10 μg/mL of 4 nm nanoparticles and 1 μg/mL of 10 nm nanoparticles was also greater than the unaltered adhesive and 1 μg/mL of 4 nm composite adhesive. The increased concentration increased the interaction of the nanoparticles with the polymer matrix and was expected to enhance the adhesive strength of the adhesive [31,59].…”

This research examined if the infusion of silver nanoparticles into a 2-octyl cyanoacrylate tissue adhesive alters the antibacterial effectiveness and mechanical properties of the adhesive. Silver nanoparticle size and concentration combinations were varied to determine the effects of these factors. Uniform distribution of the silver nanoparticles was achieved before proceeding to testing. Antibacterial effectiveness of the composite adhesive was determined via the Kirby-Bauer disk diffusion susceptibility test and by CFU counting. Doping the adhesive with silver nanoparticles resulted in an order of magnitude reduction in bacterial growth. The greatest antibacterial effect came from imbuing 10 μg/mL of 4 nm silver nanoparticles into the tissue adhesive. Despite the noticeable reduction of bacterial growth for the doped adhesives, the difference among the varying silver nanoparticle size and concentration combinations was minimal.The breaking strength of the adhesive increased when silver nanoparticles were added. The adhesive strength of the composite adhesive attached to an incised porcine sclera was also greater than the unaltered adhesive. The greatest breaking load and adhesive force was the 10 μg/mL of 10 nm silver nanoparticle-doped adhesive. The

Abstract-In this study, a simple and high sensitive electrochemical sensor is developed for the detection of fluoxetine (FXT) on a silver electrodeposited-carbon nanofiber-epoxy (AgCNFE) electrode. Cyclic voltammetry (CV) method was used for the comparative electrochemical behavior of FXT on AgCNFE, commercial silver electrode (Ag) and carbon nanofiber-epoxy (CNFE) composite electrode. A synergic effect in relation to the sensitivity for FXT detection was found on AgCNFE electrode versus commercial Ag electrode and CNFE electrode. Chronoamperometry (CA) results show that AgCNFE electrode exhibited a great potential for the real practical application in FXT detection without possible interference.Index Terms-Carbon nanofiber, silver electrodeposited, fluoxetine detection.
