“…Therefore, a better understanding of the sintering process as well as the effects of the protective agents on the conductivity of the printed Ag NPs based pattern is needed. Usually, two kinds of protective agents are commonly used in Ag NPs based inks: first, the polymers bearing carboxylate, amino or hydroxyl functional groups, such as poly(acrylic acid) (PAA) [41,42,43,44], poly(vinyl pyrolidone) (PVP) [45,46,47,48,49] and poly(vinyl alcohol) (PVA) [50,51]; second, the small molecular compounds with a long alkyl chain and polar head, such as alkanethiols [52,53,54], alkylamines [53,55,56] and carboxylic acids [57,58]. Through investigating the behavior of protective agent in sintering, some efforts have been made to improve the conductivity of the Ag NPs based ink under moderate sintering.…”

Printed electronics on flexible substrates has attracted tremendous research interest research thanks its low cost, large area production capability and environmentally friendly advantages. Optimal characteristics of silver nanoparticles (Ag NPs) based inks are crucial for ink rheology, printing, post-print treatment, and performance of the printed electronics devices. In this review, the methods and mechanisms for obtaining Ag NPs based inks that are highly conductive under moderate sintering conditions are summarized. These characteristics are particularly important when printed on temperature sensitive substrates that cannot withstand sintering of high temperature. Strategies to tailor the protective agents capping on the surface of Ag NPs, in order to optimize the sizes and shapes of Ag NPs as well as to modify the substrate surface, are presented. Different (emerging) sintering technologies are also discussed, including photonic sintering, electrical sintering, plasma sintering, microwave sintering, etc. Finally, applications of the Ag NPs based ink in transparent conductive film (TCF), thin film transistor (TFT), biosensor, radio frequency identification (RFID) antenna, stretchable electronics and their perspectives on flexible and printed electronics are presented.

“…These images provided evidence of the spherical nanostructure of individual self-assembled Ag NPs with a diameter of approximately 1 micron, which were well-dispersed, and nearly monodispersed. The number of individual silver spherical nanostructures was large in the EG solution in which Ag NPs were formed under 90 s of MW irradiation (Figure 5 G), and these structures tended to aggregate in one place [ 26 , 27 ]. The microwave expansion that occurs in the synthesis of nanocrystals is a rapid heating process that produces NPs that show very good monodispersity and crystallinity.…”

Fabrication, characterization, and thermal property evaluation of silver nanofluids

Silver nanoparticles were successfully prepared in two different solvents using a microwave heating technique, with various irradiation times. The silver nanoparticles were dispersed in polar liquids (distilled water and ethylene glycol) without any other reducing agent, in the presence of the stabilizer polyvinylpyrrolidone (PVP). The optical properties, thermal properties, and morphology of the synthesized silver particles were characterized using ultraviolet-visible spectroscopy, photopyroelectric technique, and transmission electron microscopy. It was found that for the both solvents, the effect of microwave irradiation was mainly on the particles distribution, rather than the size, which enabled to make stable and homogeneous silver nanofluids. The individual spherical nanostructure of self-assembled nanoparticles has been formed during microwave irradiation. Ethylene glycol solution, due to its special properties, such as high dielectric loss, high molecular weight, and high boiling point, can serve as a good solvent for microwave heating and is found to be a more suitable medium than the distilled water. A photopyroelectric technique was carried out to measure thermal diffusivity of the samples. The precision and accuracy of this technique was established by comparing the measured thermal diffusivity of the distilled water and ethylene glycol with values reported in the literature. The thermal diffusivity ratio of the silver nanofluids increased up to 1.15 and 1.25 for distilled water and ethylene glycol, respectively.

“…The reverse scan does not distinguish the cathodic processes due to the interference of the reduction reactions of silver species accompanied by random fluctuations that obscure the real signal of the peak. Thus, it can be assumed that the final surface layer con-struction corresponds to an assimilated model of silver interconnected to PVA film [34] that forms some bonds with the copper surface [35].…”
