“…A comparison of these images and that shown in Figure S2b of a pristine CNM-II sample suggests that the plasma treatment reduces the fiber diameter, causes the formation of beads and ellipsoids, and leads to the scission of some nanofibers. These observations are anticipated because plasma causes heating, oxidation, sublimation, and fragmentation of materials and the sublimed materials may recondense to form new structures. ,− The etching of carbon is also seen from the gradual loss of materials from the CNMs (Table ), and the mass of a CNM-II sample is decreased by 38% after 4 min of plasma treatment.…”

Electricity has been generated from evaporation-driven water flow in films of carbon soot particles and other porous media. This paper reports the placement of carbon nanofiber mats (CNMs) on fiberglass screens for the construction of efficient water-evaporation-induced generators (WEIGs). These CNMs are prepared from carbonizing electrospun polyacrylonitrile nanofiber mats and then treating them with oxygen plasma. After electrode attachment to the two ends of a CNM, one electrode is immersed into water. Water rises in the mat due to capillary action and evaporates from the mat surface due to thermal energy provided by the environment. The steady rise of water pushes the dissociated ions of the surface functionalities upward, resulting in a streaming current and an electric potential. This paper investigates how the generated short-circuit current, I s, and open-circuit voltage, V o, of the WEIG change with structural parameters of the CNMs. Under optimized conditions, these CNMs produce electricity at an areal power density of 83 nW/cm2, which is almost 10 times those offered by some existing ones. Thus, the easy-to-handle CNMs are an attractive porous scaffold for WEIGs.

“…However, AgNWs inherently possess poor interaction with the substrates, thus rendering the conductive layer easy to delaminate from the substrate when subjected to external stress, including friction, adhesion, bending or compression. 20,21 Great efforts have been made to enhance the interaction between the AgNW layer and the substrate. Functional protection layers such as nanometal oxides, 22,23 small organic molecules 1,24 or polymers, 25,26 have been proposed.…”

“…Different materials have been considered for creation of a protective coating, including reduced graphene oxide (Ahn et al, 2012;Duan et al, 2019), metal oxides and carbonates (Jeong et al, 2019;Khan et al, 2018), optical adhesive (Miller et al, 2013), chitosan (Jin et al, 2017), and polymers (Chen et al, 2014;Kim et al, 2015;Miao et al, 2019;Moreno et al, 2013;Xu and Zhu, 2012). Although the coatings could delay corrosion, 100 % of effectiveness on the long-term still remains an issue (Deignan and Goldthorpe, 2017;Jiu et al, 2015).…”

An electrochemical method to rapidly assess the environmental risk of silver release from nanowire transparent conductive films

Silver nanowires (AgNW) are new nanomaterials designed to be incorporated into transparent conductive films in electronics, microelectrodes, heated surfaces and others. Although in these films, the AgNW are generally protected by a coating material, a risk for release of silver at all stages of the nanoproduct life cycle does exist due to corrodibility of the metal. Since ionic and nanoparticulate Ag represent a toxicological risk for a large number of living cells, there is a need for quantifying the potential Ag release from these product components. We developed an electrochemical method to evaluate possible corrosion activity of silver in AgNW transparent conductive films (TCFs) and concomitant Ag + release. A polysiloxane polymer was used as protective coating of AgNW TCFs. A consistent correlation is observed between the degree of corrosion and the coatings' characteristics, in particular the thicknesses. A major advantage of the new approach, compared to classical aging studies, is the short experimentation time: 20 min are sufficient for a diagnostic result. The method is an accelerated corrosion and release test. It is green methodology with use of very low electric power and with no harmful reagents. A particularly attractive application could be in the field of environmental risk assessment of metals from portable electronics and biosensors.
