Combining a Fluoroalkylsiloxane and Ion Implantation for Hydrophilic/Hydrophobic Patterning

Cook M.J., Johnston J.H., Leveneur J., Victoria University of Wellington, NZ

We present a novel method of producing hydrophilic/hydrophobic patterning on several different substrates using a novel two-step process. The developed process involves a simple surface functionalization with a fluoroalkylsiloxane (FAS), followed by masked ion implantation. [...]

Fabrication of superhydrophobic PVDF membranes with PTFE nano-film surface coatings

Abdulhussein A.T., Kannarpady G.K., Biris A.S., University of Arkansas at Little Rock, US

Due to their outstanding corrosion resistance, wear resistance, thermal stability, and chemical stability, polyvinylidene fluoride (PVDF) membranes are extensively used for membrane distillation, membrane contactor, oil/water separation, and wastewater treatment. Modifying a PVDF membrane with [...]

Enhancement of pure titanium localized corrosion resistance by chemical oxidation

Prando D., Brenna A., Diamanti M.V., Ormellese M., Pedeferri M.P., Politecnico di Milano, IT

Titanium and its alloys are widely appreciated for their high corrosion resistance in environments that are critical even for high-end stainless steel (duplex UNS S31803 and UNS S32750), such as concentrated chlorides [1]. This resistance [...]

Graphene – Epoxy Composites for Anti-Corrosion Coatings

Bosnick K., Benhalima A., Chapleau N., Tefashe U.M., Bergren A.J., Yang Q., Champagne M.F., National Research Council Canada, CA

It is important to protect steel infrastructure, such as pipelines, from environmental corrosion. The primary method for this protection is by utilizing coatings, especially epoxy (EP) coatings. In recent years graphene has shown a great [...]

Smart Antimicrobial Coating with Endless Applications

Tiwari A., Chaturvedi A., FLORA COATINGS, US

Historically corrosion protection has been achieved through use of hexavalent chromium ions along with heavy metals in paints. These chemical ingredients are highly toxic to environment and human health. In-fact, Hex-Chrome is a known human [...]

Molecular sieve membranes made in thin sheet form

Liu W., Molecule Works Inc., US

A new molecular sieve membrane technology will be introduced in this presentation from fundamental designs to performance characteristics. Molecular sieve materials are well known for their molecular sieving functions, i.e., distinguishing individual molecules based on [...]

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 [...]

Brand Protection and Authentication Enabled By Frangible Polymer Technology

DiMaio J., Tetramer Technologies, LLC, US

Tetramer has developed a unique technology to produce pre-stressed frangible, polymeric coatings. These can be applied using traditional thin-film coating and curing techniques or more advanced 3D-printing techniques. The ability to produce stable, pre-stressed films [...]
