“…Besides, AgNWs was proven to replace indium tin oxide (ITO) in solar cell applications. According to Lee et al [12], sensors fabricated from AgNWs to detect hydrogen peroxide showed an acceptable detection limit of 46 µM with a fast response time of 2 s and high sensitivity of 749 µA mM -1 cm -2 . This is due to its nanostructure that assists the electron transfer and enhances the sensitivity of chemical sensor.…”

Malachite green is widely used in the aquaculture, food, and textile industries. However, malachite green is carcinogenic, mutagenic, and teratogenic. Therefore, a chemical sensor was developed to detect malachite green in water samples. Screenprinted carbon electrode was coated with (p(AAm-co-EMA)/Ru(bpy) 3 2+ /AgNWs to investigate its potential as a membrane for chemical sensor. The membrane was synthesized using the photopolymerization technique and characterized by fourier transform infrared (FTIR), 1 H nuclear magnetic resonance ( 1 H NMR), swelling test, field emission scanning electron microscopy/electron dispersive X-ray analysis (FESEM/EDX), thermogravimetric analysis (TGA), and cyclic voltammetry (CV). The peak of -CO in the FTIR spectra indicated that the copolymerization was successful. Furthermore, the NMR spectrum confirmed the FTIR result with the presence of peak at 4.2 ppm. Swelling test showed that p(AAm-co-EMA)/AgNWs had a lower swelling percentage than p(AAm-co-EMA) due to AgNWs filling the pores of the membrane, which can be seen in the cross section of the SEM micrograph. Thermal decomposition temperature of the membrane was around 400 °C. Cyclic voltammogram proved that the p(AAm-co-EMA)/Ru(bpy) 3 2+/ AgNWs film coated on screen-printed carbon electrode which acted as a working electrode was able to detect malachite green by showing anodic peak around 0.25 V and cathodic peak around -1.0 V.

Skrin bercetak elektrod karbon bersalut (p(AAm-ko-EMA)/Ru(bpy) 3 2+ /AgNWs telah dibangunkan bagi mengkaji potensinya sebagai filem untuk sensor kimia. Membran tersebut disintesis dengan menggunakan teknik fotopempolimeran dan dianalisis menggunakan spektroskopi infra merah tranformasi fourier (FTIR), 1 H resonans magnetik nukleus ( 1 H RMN), mikroskopi imbasan elektron pancaran medan/penyebaran elektron sinar-X (FESEM/EDX), analisis termogravimetri (TGA) dan voltametri siklik (CV). Puncak -CO yang hadir dalam spektrum FTIR menunjukkan kopempolimeran telah berjaya. Spektrum NMR mengesahkan spektrum FTIR dengan kehadiran puncak pada 4.2 ppm. Ujian penyerapan air pula menunjukkan peratus serapan air p(AAm-ko-EMA)/AgNWs lebih rendah berbanding p(AAm-ko-EMA) kerana AgNWs memenuhi liang-liang yang terdapat dalam filem seperti yang ditunjukkan pada mikrograf keratan rentas SEM. Penguraian terma berlaku pada suhu 400 °C.

“…Performances of flexible sensors concern about the linearity, sensitivity, detecting range, response time, stability and stretchability. Investigations using AgNW electrodes mainly concern about strain sensors [40,41], pressure sensors [40] and electrochemical sensors [42]. Yao et al presented wearable sensors based on highly stretchable AgNW electrodes enabling the detection of strain and pressure [40].…”

There has been an explosion of interests in using flexible transparent electrodes for nextgeneration flexible electronics, such as touch panels, flexible lighting, flexible solar cells, and wearable sensors. Silver nanowires (AgNWs) are a promising material for flexible transparent electrodes due to high electrical conductivity, optical transparency and mechanical flexibility. Despite many efforts in this field, the optoelectronic performance of AgNW networks is still not sufficient to replace the present material, indium tin oxide (ITO), due to the high junction resistance. Also, the environmental stability and the mechanical properties need enhancement for future commercialization. Many studies have attempted to overcome such problems by tuning the AgNW synthesis and optimizing the film-forming process. In this chapter, we survey recent progresses of AgNWs in flexible electronics by describing both fabrication and applications of flexible transparent AgNW electrodes. The synthesis of AgNWs and the fabrication of AgNW electrodes will be demonstrated, and the performance enhanced by various methods to suit different applications will be also discussed. Finally, technical challenges and future trends are presented for the application of transparent electrodes in flexible electronics.

“…While the vast majority of such networks is employed as transparent conductors, they also provide interesting platforms for catalytic applications, as they can serve as transparent (as well as flexible) electrocatalyst layers. Along these lines, planar Ag nanowire networks have been utilized as flexible, amperometric H 2 O 2 sensors ( Figure 3) [39], and Cu nanowire networks were used in the hydrogen evolution reaction [40]. It should be noted that in such 2D nanowire networks, a trade-off between the nanowire areal density (and thus, the catalytically active surface area) and the optical transmittance has to be made.…”

Combining 1D metal nanotubes and nanowires into cross-linked 2D and 3D architectures represents an attractive design strategy for creating tailored unsupported catalysts. Such materials complement the functionality and high surface area of the nanoscale building blocks with the stability, continuous conduction pathways, efficient mass transfer, and convenient handling of a free-standing, interconnected, open-porous superstructure. This review summarizes synthetic approaches toward metal nano-networks of varying dimensionality, including the assembly of colloidal 1D nanostructures, the buildup of nanofibrous networks by electrospinning, and direct, template-assisted deposition methods. It is outlined how the nanostructure, porosity, network architecture, and composition of such materials can be tuned by the fabrication conditions and additional processing steps. Finally, it is shown how these synthetic tools can be employed for designing and optimizing self-supported metal nano-networks for application in electrocatalysis and related fields.
