Photoinitiators for visible-light induced living polymerization A new class of photoinitiators of living polymerization induced by visible light has been developed and is made available for testing (under MTA) and/or licensing. The developed initiators trigger the curing of resins by irradiation with low-intensity visible light, while providing polymers with good control of chain length. In addition, through decomposition of the initator, the cured material presents a different colour than the uncured resin.

Metal-ceramic composites and nanocomposites for aerospace and automotive industry (POIG.01.03.01-14-013/08)Nanocrystalline alloy (Ni-Mo, Ni-W) and composite (Ni-Mo/Al2O3, Ni-Mo/Al2O3) coatings Metallic alloys of Ni-Mo and Ni-W were deposited from solutions containing sodium molybdate (Na2MoO4) or sodium tungstate (Na2WO4), and nickel sulphate (NiSO4), as the source of Mo(VI), W(VI) and Ni(II) ions, respectively. As the complexing agent citrate ions (C6H5O73-) were used, introduced into solutions in the form of sodium citrate (Na3C6H5O7). In the bath for Ni-W coatings electrodeposition, sodium chloride (NaCl) and ammonium chloride (NH4Cl) were additionally added as factors increasing the conductivity of the solution. The pH of the electrolyte solution was adjusted with the appropriate amount of H2SO4 or NH4OH.

New non-destructive method for “in situ” monitoring of anticorrosive protection of organic coatings The main novelty of the device and procedure is the new portable sensor adaptable to virtually any surface. The device, fixable by vacuum to the surface under study, makes possible the measurement of the electrochemical interfacial impedance, that is the main parameter of interest for adherence quality and anti-corrosion performance.

A novel mild and efficient method to prepare ε-Caprolactam precursor of Nylon 6 ε-Caprolactam, the main precursor of the synthetic fibber Nylon 6, is prepared from cyclohexanone oxime by treatment with a new salt as promoter. This procedure requires mild reaction conditions and affords excellent levels of conversion and selectivity to obtain pure ε-caprolactam. No reaction by-products are formed. The new promoter salt is cheap, no corrosive, and easy to prepare. All these characteristics makes the procedure suitable for undustrial purposes.

Environmentally friendly processing of thermosets by two-stage sequential aza-Michael addition and free-radical polymerization of amine-acrylate mixtures Environmentally friendly preparation of thermosets for applications on thermosensitive substrates. A two-step curing process, which consists in an Aza-Michael addition at room temperature, followed by UV radical polymerization of acrylates or methacrylates amine formulations without the need of adding solvents. The presence of amines in the structure suppress the radical inhibition by oxygen, which is a typical drawback in radical polymerizations. The invention allows leading the curing in two separate stages with a stable intermediate material, being the process controlled by the amount of amine in the formulation.

iSeal: Advanced Surface Treatment for Protection against Tribocorrosion This invention is based on the application of a hybrid organic/inorganic treatment onto an exposed surface – either as a stand-alone treatment or as a sealant. The treatment is applied using an electrochemical deposition technique, allowing for the development of conformal coatings, irrespective of design complexity. Layer thicknesses are low (10-100nm) but resistance in corrosive marine environments indicate corrosion rates comparable to technologies currently employed by the aerospace and automotive industries. Corrosion rates are reduced by between 103 and 105 times, dependant on the nature of the porous coating. Tests on metallic coatings indicated a reduction in corrosion rates of approximately 103-104 while tests on ceramic coatings indicated a reduction in corrosion rates of approximately 105. By applying the hybrid treatment as a sealant treatment onto a porous wear resistant coating, concerns regarding the effect of mechanical damage are dramatically reduced. In addition, surface roughness levels are similar to electropolished finishes.
