Compositions comprising surface-modified nanocalcite particles dispersed in a curable resin system comprising a vinyl ester, and coatings and fibrous composites incorporating such compositions are described. The surface-modifying agents include a binding group ionically associated with the calcite and a compatiblizing segment, compatible with the curable resin. The surface-modifying agent may also include a reactive group capable of reacting with the curable resin system. Methods of preparing nanocalcite composites and coating a fibrous composites prepared from such nanocalcite composites are also described.

Pressure vessels formed from fiber composites are described. The fiber composites include fibers impregnated with a resin system containing surface-modified nanoparticles dispersed in a curable matrix resin.

Composite pressure vessels

Methods of compounding nanoparticles with a resin, e.g., a curable resin and one or more surface modifying agents are described. The methods use wet milling technology, including both continuous and batch milling processes, and can be used to functionalize the nanoparticles and disperse the functionalized nanoparticles into the resin system in a single process. Methods of compounding curable resin systems containing reactive diluents are also disclosed.

Solventless functionalization, milling, and compounding process with reactive diluents

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.

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.

Microstructured optical films, assemblies of films including at least one microstructured optical film, and (e.g. illuminated) display devices including a single microstructured optical film or assembly.

Optical film assembly and display device

A durable optical film or element includes a polymerized structure having a microstructured surface and a plurality of surface modified colloidal nanoparticles of silica, zirconia, or mixtures thereof. Display devices including the durable microstructured film are also described.

Light management films and methods of making light management films are described. The light management films contain an optical layer that contains polymeric material and zirconia particles. The zirconia particles are colloidal, crystalline, substantially non-associated, and have a narrow size distribution.
