A durable optical film includes a polymerized optical film structure having a microstructured surface and a scratch contrast ratio value in a range of 1.0 to 1.65 or 1.0 to 1.15. These durable optical films can include a plurality of nanoparticles and a rounded prism apexes microstructure.
摘要:
Plastic articles can be coated with polymerizable compositions containing a vinyl-functional crosslinkable film former, a large amount of benzotriazole and a copolymerizable monomer that solubilizes the benzotriazole. The cured compositions help protect the article from UV exposure and other weathering effects.
摘要:
Thermoset polymer composite wires including a multiplicity of substantially continuous fibers embedded in a solidified polymer composite matrix and forming a substantially continuous filament, the solidified polymer composite matrix further including a polymer formed by curing a polymer precursor from a liquid state and a multiplicity of nanoparticles having a median diameter of one micrometer or less substantially uniformly dispersed throughout the polymer composite matrix, and optionally, a corrosion resistant sheath surrounding the substantially continuous filament. In some embodiments, the multiplicity of particles includes surface-modified particles having a core and a surface modifying agent associated with the core and reacted with the polymer cured from a liquid state. Stranded cables including one or more such thermoset polymer composite wires, and methods of making and using such thermoset polymer composite wires and stranded cables are also described.
摘要:
The use of nanoparticles, including surface-modified silica and calcite nanoparticles, as processing aides for pultrusion is described. The methods include combining a resin system containing a resin and the nanoparticles with continuous fibers, pultruding this combination, and at least partially curing the resin. The methods are suitable for use with a wide variety of resins and fibers, and may be used to reduce the pull-force at a fixed fiber volume loading, increase the fiber volume loading, or both. Pultruded parts made by these methods and pultruded parts with high volume loadings of fibers are also described.
