  • Corrosion Inhibiting Self-Expanding Foam | TechLink
    foam formed by reacting polyols with an isocyanate compound and a 2 to 10 percent by weight of either an organic or inorganic gas phase corrosion inhibitor The closed cell foam provides a barrier protection for the underlying corrodible surface while the inhibitor protects the metal from the absorbed moisture vapor thereby preventing corrosion from occurring at the foam metal interface The resulting foam and inhibitor composition maintains better adhesion

  • Hyperbranched Poly(ether-ketone): Easy to Functionalize Carbon-based Nanocomposites | TechLink
    high performance applications This nanocomposite consists of carbon nanofibers nanotubes CN coupled to carboxylic acid terminated hyperbranched poly ether ketone polymers HBP PEK or its derivatives The resultant HBP PEK CN have considerably better solubility than their linear analogues The use of the hyperbranched aromatic greatly enhances the organosolubility and processing options of carbon nanomaterials The carboxylic acid terminated HBP PEK is highly amenable to chain end modifications that will allow controllable changes to the physical properties of the resultant functionalized carbon based nanocomposites Functional groups that could be readily derived from carboxylic acid include amine esters and benzothiazole The result is the ability to impart a dramatic range of physical characteristics to these carbon nanomaterials enabling application specific functionality such as ion conductivity for battery applications and thermal modulations for higher temperature use Benefits Excellent Solubility Substantial improvements over linear analogues make feasible the solubilization of much wider and extremely long nanotubes and generally broaden processing options for carbon nanomaterials Reduced Viscosity Amenable to high speed large area spraying and painting applications Processing Friendly No observed gelation from cross linking reactions One Pot Potential Improved ease of manufacture possible through Schmidt reaction chemistry Highly Customizable HBP PEK chemistry is

  • Simple, Accurate Method for Contact Angle Measurement | TechLink
    specialized technicians In TAM an angular feature is created from the solid material in question and the contact angle is determined indirectly by observing at what angle the liquid fills the vertex see figures on right The transition angle at which the liquid wets the vertex completely can be used to readily calculate the contact angle of the liquid on the material in question The angular features can be dynamically created with a hinged surface or with a series of preformed progressively wider angled grooves The TAM method is much easier to accomplish than observing the contact angle directly Benefits High design flexibility Device implementation can be as simple as a molded form with visual inspection to a fully automated system Accurate Even in the simple versions a one degree accuracy is attainable Easy to implement Low complexity in manufacture and use The Opportunity Potential Applications Examples Kit For repetitive testing a self contained kit can be readily designed Disposable device For testing of aggressive chemicals such as strong acids it may be desirable to have a solution that can be priced at the disposable level Field instrument TAM does not need complicated image capture and analysis hardware and software
