All-printed liquid crystal display devices made from sol-gel Indium tin oxide(ITO) ink

Xia N., Gerhardt R.A., Georgia Institute of Technology, US

Indium tin oxide (ITO) is the most widely used transparent conducting oxide due to its high conductivity and transparency. It is currently used in a wide range of devices that require transparent conducting electrodes. Currently, [...]

Perfluoropolyethers as superhydrophobizing agents for carbon-based surfaces of fuel cell gas diffusion layers

Navarrini W., Sansotera M., Diamanti M.V., Pedeferri MP., Gola M., Dotelli G., Politecnico di Milano, IT

Perfluoropolyether (PFPE) peroxide has been employed in the functionalization of conductive carbon-based materials to confer them the highly hydrophobic surface properties of the perfluorinated materials. The thermal decomposition of a linear PFPE peroxide produced PFPE [...]

Effects of Poly-(N-vinyl-2-pyrrolidone) Additive on Direct-Inkjet-Printed Silver Nitrate Conductive Lines

Liu Y-F, Feng P.H., Tsai H.L., Hwang W-S, National Cheng Kung University, TW

All-printed electronics has attracted attention due to their fast processing and low cost. Inkjet printing allows circuit components to be directly drawn at a specific area in one step. The printed patterns can be used [...]

Gravure Printed Network Based on Silver Nanowire for Transparent Electrode

Lin J., Gu W., Cui Z., Suzhou Institute of Nanotech and Nanobionics, Chinese Academy of Sciences, CN

Transparent electrodes are critical components of optoelectronic devices such as solar cells, organic light-emitting diodes, and displays. Most high-performance transparent conducting films at present are composed of sputtered metal oxides, which have limited flexibility because [...]

Platinum Silicide probes: A novel approach to manufacture highly conductive AFM probes with small radii and high wear resistance

Krause O., Sebastian A., Despont M., Nanoworld Services, DE

Conventionally, conductive Atomic Force Microscopy (c-AFM) probes are either made by depositing a metal, an alloy or a doped diamond layer onto a ready-made AFM probe or, alternatively, by depositing one of those materials into [...]

Advancements in Ink-Jet Deposition of Carbon Nanotube Materials for Printed Electronics

Turner S., Brewer Science, US

Advancements in the separation, purification, and post processing of metallic carbon nanotubes are enabling these materials to be used in new printed electronic devices. While CNTs have been researched for over 10 years, recent innovations [...]

Dip Pen Nanolithography® of Silver Nanoparticle Inks for Printed Electronics

Parpia M., Tevaarwerk E., Amro N., Wang H.T., Haaheim J., Rozhok S., Levesque T., Nafday O.A., NanoInk, US

Precision nanoscale deposition of biological, organic, and inorganic materials is a fundamental need in nanoscience research. Dip Pen Nanolithography® (DPN®) is an inherently additive, SPM-based technique, capable of producing nanoscale features with high resolution and [...]

Broadcast Photonic Curing of Metallic Nanoparticle Films

Schroder K.A., McCool S.C., Furlan W.R., Nanotechnologies, Inc., US

A novel and industrially scalable technique is presented for curing metal nanoparticle based films in which a large area uncured film is made highly conductive by exposure to a brief, intense pulse of light from [...]
