摘要:
Provided is a phosphor-functionalized nanoparticle that includes an inorganic nanoparticle core; surface polymer brushes that include a plurality of long-chain polymers bonded to the surface of the inorganic nanoparticle core, said long-chain polymers each having molecular weight greater than 500, and a plurality of short-chain polymers bonded to the surface of the inorganic nanoparticle core, said short-chain polymers each having molecular weight less than 0.5 times the average molecular weight of the long-chain polymers; and one or more organic phosphors bonded to at least one of the inorganic nanoparticle core and one or more of the plurality of short-chain polymers. Graft density of the short-chain polymers on the surface of the inorganic nanoparticle core (σSC) is greater than graft density of the long-chain polymers on the surface of the inorganic nanoparticle core (σLC). Also provided are polymer matrices, LED's, optical systems, lighting devices, and fixtures that include the inventive nanoparticle.

In an example, a flame-retardant, cross-linked polyhydroxyalkanoate (PHA) material includes a first PHA material that is cross-linked to a second PHA material via a phosphorus-based cross-linker.
摘要:
A resin composition containing fine paper powder used in molding is obtained by using a fully-intermeshing type co-rotating twin-screw kneading extruder (10) having two material feeding ports (15 and 16) to knead a raw material containing a fine paper powder having an average particle diameter of 10 to 100 μm from 20 to 70 parts by weight and a thermoplastic resin from 30 to 80 parts by weight, a sum of the fine paper powder and the thermoplastic resin being 100 parts by weight, by feeding the thermoplastic resin through a main material feeding port (15) and the fine paper powder through a sub material feeding port (16).
摘要:
The invention relates to a process for the preparation of a phosphated polycondensate, at least one sulphonic acid being used as catalyst, and to the use of the phosphated polycondensate obtained as an admixture for aqueous suspensions of hydraulic and/or latently hydraulic binders.
摘要:
A phosphazene compound having a vinyl group is manufactured by a reaction between a vinyl compound and a phosphazene compound having a hydroxyl group and added to a resin composition for manufacturing a prepreg or a resin film so as to be applicable to copper-clad laminates and printed circuit boards to thereby achieve satisfactory circuit laminate properties, namely low coefficient of thermal expansion, low dielectric properties, heat resistant, fire resistant, and halogen-free.
摘要:
A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises an aldehyde or ketone and an amine salt of an inorganic acid. The composition when applied to fiberglass is cured to form a water-insoluble binder which exhibits good adhesion to glass. In a preferred embodiment the composition when applied to fiberglass provides a sufficient blackness required in facer products.
摘要:
A method for making a phosphorated polymer is also provided. An organic polymer and phosphorus are mixed to obtain a mixture. A weight ratio of the organic polymer to the phosphorus ranges from about 1:10 to about 4:1. The mixture is dried in an inert atmosphere or vacuum. The mixture is heated in an inert atmosphere or vacuum so that the phosphorus sublimes and reacts with the organic polymer to form a preform. The preform is cooled down to room temperature and immersed in an alkaline solution. The pH of the preform is adjusted to be neutral. The preform is dried.
摘要:
Polymer combinations which contain: at least one first polymer (PZ) containing zwitterionic structural units; and at least one other polymer (P) carrying charged substituents and capable of bonding with the at least one first polymer (PZ), are applied onto the face surface(s) of solid materials to modify the surface properties thereof.
