Silver nanowire inks for fabrics

Güven, Merve Nur
Conductive inks are used extensively in electronic devices like sensors, batteries, photovoltaic devices, antenna and organic light emitting diodes. These inks typically made from silver. Wearable technology is another industry which requires inks to be flexible. These devices need low temperature cured silver pastes. Low temperature pastes typically make use of silver nanoparticles. These pastes have some problems with sintering and substrate adhesion. In this thesis, to overcome these problems, silver nanowires are used to formulate pastes. Conductivity, bonding strength, flexibility, transparency and compliance of the silver nanowire pastes were determined. Promising performance of was obtained from silver nanowire pastes due to the one dimensional nature of the nanowires in terms of adhesion to fabric surface. Silver nanowires have a big area to adhere, network form of them is more conductive and transparent than network form of silver nanoparticles. The aim of this study is fabrication of low temperature silver paste by synthesis long silver nanowires.


Silver nanowire networks on polydimethylsiloxane for organic and perovskite solar cell electrodes
Güner, Elif Özlem; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2019)
Transparent and conductive electrodes are widely used in optoelectronic devices. The most prominent and commercial transparent conductive electrode is indium tin oxide (ITO). However, there is an increasing demand to replace ITO with alternative materials due to inherent drawbacks of ITO such as its cost, brittleness and scarcity of indium. Silver nanowire (Ag NW) networks are among the best candidates to replace ITO with their excellent optoelectronic and mechanical properties. Ag NW networks have already ...
Characterization and contact resistivity studies of ito thin films for use in silicon heterojunction solar cells
Güler, Seçil; Erçelebi, A. Çiğdem.; Department of Physics (2020)
Transparent conductive oxides (TCO) are widely used in optoelectronic devices such as flat panel displays and solar cells. Indium tin oxide, due to its wide optical bandgap and high transmittance in the visible spectrum, is commonly used for device applications such as anti-reflective coating, front TCO layer in silicon heterojunction solar cells. When ITO is used as TCO layer, the carrier transport mechanism through the junction is improved due to the decrease in the free carrier absorption. In this study,...
Proton irradiation and gamma-ray irradiation testing studies on the commercial grade GaNFETs to investigate their characteristics under the space radiation environment
Boyacı, Lütfi; Keysan, Ozan; Department of Electrical and Electronics Engineering (2019)
In this thesis, the radiation performances of the commercial GaNFETs were investigated for the possible future integration of these devices to the power subsystems of the satellites as a main switching power element instead of the Silicon MOSFET. Two main irradiation tests were applied to the GaNFETs, namely proton irradiation test, and gamma-ray irradiation test. By these tests, tough space radiation environment was simulated to understand the GaNFET’s radiation performances. In the proton irradiation test...
Production and characterization of nano silver oxide for silver zinc batteries
Yurtseven, Özüm Öyküm; Aydınol, Mehmet Kadri; Nalbant Esentürk, Emren; Department of Micro and Nanotechnology (2013)
Rechargeable silver-zinc batteries have aroused interest and find various area of usage depending on their notably technical advantages over other battery systems including their high specific energy and high recharge efficiency. In this battery chemistry, silver oxide and metallic zinc are used as the positive and negative active materials respectively. Chemically stabilized particles with large surface areas are needed to reach high discharge rates for battery applications. The use of nanoparticles as ele...

Doğanay, Doğa; Genlik, Sevim Polat; Ünalan, Hüsnü Emrah (IOP Publishing, 2016-10-28)
The modification of insulating fabrics with electrically conductive nanomaterials has opened up a novel application field. With the help of Joule heating mechanism, conductive fabrics can be used as mobile heaters. In this work, heatable textiles are fabricated using silver nanowires (Ag NWs). Cotton fabrics are decorated with polyol synthesized Ag NWs via a simple dip-and-dry method. The time-dependent thermal response of the fabrics under different applied voltages is investigated. It is found that the fa...
