A Bulk, Low Energy Surface Treatment for Three Dimensional Substrates via CVD Processing

Smith D., Patterson L., SilcoTek Corporation, US

There are myriad potential applications and a significant need for low energy surfaces. The gas-phase modification of three dimensional structures, such as fittings, tubing, valves, or manifold blocks, in high volume, to give hydrophobic and [...]

Wettable Slippery Surfaces. Self-cleaning Effect and Mechanism

Law K-Y, Research and Innovative Solutions, US

The phenomenon of self-cleaning displayed by the Lotus leaf and many other plant and insect surfaces has attracted tremendous attention recently. Self-cleaning surface is usually superhydrophobic and non-wettable, and is characterized by a very large [...]

Zinc phosphate micro flakes as new corrosion inhibition additives in coatings and paints

Perre E., Albayrak S., Becker-Willinger C., INM - Leibniz Institute for New Materials, DE

Corrosion protection is a constant concern to steel manufacturers and users. Various processes were developed in the past to provide corrosion protection for steel such as metallic layers like e.g. zinc, coating of the metal [...]

Environmentally Friendly Protective Coatings for Metals and Alloys

Ryabova E., Dawley J., Ryabov V., Ryabova E., Mah C., Advenira Enterprises, Inc., US

The operation and maintenance of machines and mechanisms, as well as outdoor structures, conducted by various industries across the board is a costly process due to corrosion of metals and/or alloys, from which the vast [...]

Relationship between Morphology and Electrochemical Properties of Polyaniline in the Nanometer Regime

Lee Y., Yoon H., Chonnam National University, KR

Polyaniline (PANI) has found a wide range of applications due to its electrical properties, reversible redox behaviors and environmental stability. Here, we report the preparation of PANI nanostructures with three different aspect ratios, namely, nanospheres, [...]

Durable Superhydrophobic Coatings for Icephobic Applications

Nahum T., Mitra S., Panwar A., Barry C., Dodiuk H., Kenig S., Mead J., UMass Lowell, US

Recent studies about the application of superhydrophobic surfaces for anti-ice properties have found that ice adhesion strength is reduced significantly compared to bare aluminum surfaces, but these surfaces lack durability. In this work, bottom up [...]

Polymer Nanostructure Approach for Photoelectric Solar Energy Conversions

Sun S., Norfolk State University, US

At materials molecular level, photoelectric/photovoltaic conversion corresponds to a photo induced electron transfer from a molecular electron rich donor entity to an electron deficient acceptor entity, and the process is also called photo induced exciton [...]

Kinetically Controlled Formation of Deposited Polymer Nanomaterials with Unique Surface Substructures

Choi H., Yoon H., Chonnam National University, KR

One-dimensional (1D) electronic materials with inherent nanoscale features are considered to be promising components for achieving unprecedented future technologies. Much effort has been devoted to the synthesis of inorganic nanomaterials and, as a result, unique [...]

Conjugated Polymer Papers for Metal Ion Detection

Ahn K-J, Yoon H., Chonnam National University, KR

It is of great importance to detect heavy metal ion in solution. Here, we describe the electrochemical detection of metal ions using polypyrrole/cellulose (PPCL) composite papers in both static and flow systems. A home-made electrochemical [...]
