Clay Polyimide Composite Film with Low CTE and High Water Vapor Barrier Property

Ebina T., Kawasaki K., Nakamura T., Yoshida M., Hayashi H., Hayashizaka N., Yamashita T., Yamamoto T., Misyou D., Bando S., Hayashizaka N., Umeda Y., National Institute of Advanced Industrial Science and Technology, JP

A new clay polymer composite film was prepared by mixing specially processed non-swelling clay and polyimide at an optimal ratio. The newly developed film (80 µm thick) was heat-resistant at 450°C and showed very little [...]

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 [...]

Crystallization and optical properties of CCTO thin films under pressure influence

Sequinel T., Tebcherani S.M., Varela J.A., Kubaski E.T., Oliveira L.H., Siu Li M., Universidade Estadual Paulista, BR

The goals of this work were to decrease the synthesis temperature of CCTO thin films using the pressure method, and to improve the homogeneity and density of the CCTO films in order to obtain better [...]

Lareg area LbL films: the power of reflection over absorption

Wang B.N., Rieken K., Svaya Nanotechnologies, US

Layer by layer assembly is a powerful nanotechnology thin film deposition process that enables the creation of highly uniform multilayer optical films. Svaya is using this technology to create highly reflective UV, Visible and IR [...]

Role of the carbon nanocoating on the electronic conductivity of LiFePO4 based electrodes for lithium ion batteries

Badot J.C., Seid K.A., Dubrunfaut O., Levasseur S., Lestriez B., Guyomard D., CNRS, FR

Recently, we used the broadband dielectric spectroscopy (BDS), from low (a few Hz) to microwave (a few GHz) frequencies. This technique is very sensitive to the different scales of the electrode architecture involved in the [...]

Flexible Organic-Inorganic Core-Shell Nanofibers by Electrospinning and Atomic Layer Deposition

Kayaci F., Ozgit-Akgun C., Donmez I., Biyikli N., Uyar T., Bilkent University, TR

We report on the fabrication of organic-inorganic core-shell nanofibers by using two-step approach; electrospinning and atomic layer deposition (ALD). In the first step, nylon (polymeric organic core) nanofibers having different average fiber diameters were electrospun [...]

Understanding How Nanopatterning Affects Protein Deposition

Casey B.J., Silverstein J.S., Kofinas P., Dair B.J., U.S. Food and Drug Administration, US

This work focuses on understanding the effects that nanotopology has on protein adsorption. Functionalized block copolymers were synthesized and processed to produced highly ordered, nanopattered films. Experiments utilizing a quart crystal microbalance were completed to [...]

Evaluation of stability for monolayer injection molding tools coating

Cech J., Taboryski R., DTU, DK

We tested and characterized molecular coating of Aluminium and Nickel prototype molds and mold inserts for polymer replication via injection molding (IM). X-Ray photoelectron spectroscopy (XPS) data, sessile drop contact angles with multiple fluids, surface [...]

Template-based synthesis of AlN hollow nanofibers via plasma-enhanced atomic layer deposition

Ozgit-Akgun C., Kayaci F., Donmez I., Uyar T., Biyikli N., Bilkent University, TR

We report on the synthesis of AlN hollow nanofibers by plasma-enhanced atomic layer deposition (PEALD) using electrospun polymeric nanofibers as templates. Three templates with different average fiber diameters were obtained by electrospinning of polymeric solutions [...]

Nanostructure Formation of Platinum (Pt) Clusters on K-OMS-2 Manganese Oxide Paper by Reactive Spray Deposition Technique (RSDT) – CO Oxidation and Conductivity Measurements

Garces H.F., Roller J., King’ondu C., Maric R., Suib S.L., University of Connecticut, US

Nano-cluster formation of Platinum (Pt) on a modified K-OMS-2 manganese oxide inorganic paper by reactive spray deposition technology (RSDT) is presented. RSDT was employed to produce a film on the inorganic K-OMS-2 paper material. The [...]
