Comparative study on the optical, surface mechanical and wear resistant properties of transparent coatings filled with pyrogenic and colloidal silica nanoparticles
We applied two kinds of silica nanoparticles, i.e. colloidal and pyrogenic ones, to improve the performance of transparent coatings on polymer substrates. The urethane–acrylate oligomer was mixed with varied concentrations of silica nanoparticles, spin-coated onto polycarbonate substrate and finally cured by ultraviolet rays. The resultant thickness of the coatings can be controlled in ...

High-refractive-index transparent coatings enhance the optical fiber cladding modes refractometric sensitivity
The high order cladding modes of standard single mode optical fiber appear in quasi-degenerate pairs corresponding to mostly radially or mostly azimuthally polarized light. In this work, we demonstrate that, in the presence of a high-refractive-index coating surrounding the fiber outer surface, the wavelength spacing between the orthogonally polarized cladding modes families can be drastically enh...

[J. Am. Chem. Soc.] Rare Earth Metal-Mediated Group-Transfer Polymerization: From Defined Polymer Microstructures to High-Precision Nano-Scaled Objects
Poly(2-isopropenyl-2-oxazoline) (PIPOx) and poly(2-vinylpyridine) (P2VP) have been efficiently synthesized using bis(cyclopentadienyl)methylytterbium (Cp2YbMe) as catalyst. The polymerizations of 2-isopropenyl-2-oxazoline (IPOx) and 2-vinylpyridine (2VP) follow a living group-transfer polymerization (GTP) mechanism, allowing a precise molecular-weight control of both polymers with very narrow mo...

NOVEL ELECTROACTIVE POLYMER COATINGS AS VIABLE ALTERNATIVES FOR CHROMATE CONVERSION CONTAINING COATINGS:SYNTHESIS AND CORROSION MECHANISM STUDY
关键字：NOVEL,ELECTROACTIVE,POLYMER,COATINGS,VIABLE,ALTERNATIVES,FOR,CHROMATE,CONVERSION,CONTAINING,COATINGS,SYNTHESIS,AND,CORROSION,MECHANISM,STUDY,
Chromate conversion coatings (CCC) are applied via immersion or spraying onto both aluminum and steel substrates. These coatings provide both corrosion inhibition and adhesion promotion between the primer and the substrate.
