Novel Low-energy Super hydrophilic Alloy Coatings

Hou F., Mardon I., Yang Z., Goode C., Cirrus Materials Science Ltd., NZ

Cirrus technology offers a low-voltage, non-toxic PEO super hydrophilic coating technology for application to light alloys. The novel surface finishing technology provides thin, adherent, and durable protection for alloys at low cost with an exceptionally [...]

Molecular Modeling of Low-Emissivity Materials

Schweizer S., Low J.J., Subramanian L., Scienomics, US

Reducing heat transfer through thermal radiation is of main importance for energy efficient building. The emissivity of a material plays a central role in this context. Using low-emissivity (low-e) building materials is a very efficient [...]

Coatings for next-generation harsh environment systems.

DiMaio J.R., Shaughnessy M., Berger K., Morgan B., Haldeman A.T., Tetramer Technologies, US

From space to oil and gas wells, polyimide coatings and films are used to protect critical components such as fiber optic cables, enameled wires, and sensors in harsh environments. Polyimide materials provide exceptional thermal durability, [...]

Anti-Fouling CVD Coatings and Surface Modifications for Industrial Applications

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

Academia has witnessed a surge in novel coating materials and methods to control the behavior of surfaces in a variety of applications, specifically where non-stick properties (low surface energy) are desired. However, few of these [...]

Performance and Aging of Graphene Oxide/Polyurethane Nanocomposites

Goodwin Jr. D.G., Bernard C., Stanley D., Nguyen T., Sung L., National Institute of Standards and Technology, US

Graphene oxide (GO) can be used to enhance the properties and extend the service life of polymer nanocomposites (PNCs). GO is a good nanofiller candidate for water-borne polyurethane (WBPU) coatings since GO has outstanding physicochemical [...]

Thin Ceramic Coatings and Their Suitability Towards Scale Reduction in Heat Exchangers

Santos O., Nilsson M., Jensen A.H., Christiensen, A.B., Alfa Laval AB, SE

Scaling of heat exchangers in the chemical industry, district heating, power plants, etc results in a loss of performance which leads to production stops for cleaning and therefore increased operation costs. One approach to mitigate [...]

Durable Color Matching Coatings for Vehicle Tires

Koene B.E., Mullins A., Thornton M., Newsome M., Luna, US

Luna developed a durable coating system that can be color-matched to currently used Chemical Agent Resistant Coating (CARC) systems currently used on Army vehicles. Signature management technology such as camouflage coatings on military tactical vehicles [...]

Characterization of Nanoparticles in Wood Coating Stains and OSHA HazCom Compliance

Saldivar A., Burrelli L., AMA Analytical, Inc., US

Recent marketing of manufactured products for the construction trades has touted the use of engineered nanoparticles in there formulations. For this study, commercially available wood waterproofing stains were obtained that specifically identified “Nano Particle Technology” [...]

Layer-on-layer Assembly of Macroscopic 2D and 3D Carbon Nanomaterial Architectures

Patel S.C., Lalwani G., Alam O., Grover K., Qin Y-X, Sitharaman B., Stony Brook University, US

Although carbon nanomaterials are often labeled as the future replacement for silicon in electronics and a new generation of robust materials, there are major shortcomings in the assembly of carbon nanomaterials into higher order structures. [...]

Coating Resistance to Biofouling Inception for Freshwater Vehicles

Malm P., Krishnan G., Loth R., Steele A., Bayer I., University of Virginia, US

Preventing biofouling in natural bodies of freshwater is important for a wide variety of applications. The relationship between surface properties and antifouling has been the subject of many recent studies, with primary focus on long-term [...]
