Morphology, Electrical, and Rheological Properties of Silane‐Modified Silver Nanowire/Polymer Composites

Abstract

Electrically conducting films containing AgNws, hydrophilic and hydrophobic resins were prepared. FT‐IR reveals that the interface between the AgNws and epoxy could be successfully modified by APTES. XPS shows that the AgNws were attracted by hydrogen bonds of NH2 and NH groups after APTES modification. SEM analysis shows that the AgNws were well dispersed in the resin. The AgNws were also blended with hydrophilic and acrylic resins, and the resulting blends were compared with AgNws/epoxy blends. Results show that AgNw/PVA‐resin films possess the lowest surface electrical resistance. The AgNw/PVA‐resin and silane‐modified AgNw/epoxy resin conductive films possess a similar electrical percolation threshold.

Electrical, mechanical and thermal properties of aligned silver nanowire/polylactide nanocomposite films

“…A conductivity change within 18 orders of magnitude is obtained for the fabricated samples. Conductivity at 1.74 vol % is an order of magnitude lower than those reported in the literature for the same nanowire content [12,13,43]. It is attributed to the alignment of Ag NWs within the PLA matrix.…”

“…However, due to oxide layer formation on Cu and Ni NWs, maximum conductivity of the nanocomposites could not exceed 10 À1 S/m [9,10]. In contrast, higher conductivity values were reported from the nanocomposites fabricated with Ag NWs [12,13].…”

Concept of a Conducting Composite Material for Lightning Strike Protection

“…[27], however the problem with too low electrical density to carry on lightning charge still remains. The alternative solution of dispersion of metallic (aluminium, copper, nickel, silver and gold) nanowires into dielectric polymeric matrix solves this problem [30][31][32], however it does not indicate an improvement in conductivity over traditional metallic meshes [33], but the cost of manufacturing of such structures is much higher than for metallic meshes.…”

Electrical, morphological, and electromagnetic interference shielding properties of silver nanowires and nanoparticles conductive composites

“…Accordingly, silver nanomaterials needed to be modified by silane couple agent and obtain excellent dispersion in hydrophobic resins. In our earlier study [28], modified silver nanowires can be dispersed well in Epoxy resin by 3-Aminopropyltriethoxysilane (APTES) modification with ex-situ processes. It also verified that the well dispersion of Ag nanowires could possess a lower percolation threshold.…”
