    Abstract: The present invention provides a method for producing silver nanoparticles by employing ethanolamine. The method of this invention can be easily operated and no organic solvent is required. Ethanolamine first reacts with copolymers of poly(styrene-co-maleic anhydride) (abbreviated as SMA) to generate polymeric polymers. The polymeric polymers then reduce silver ions to silver atoms which are dispersed in the form of silver nanoparticles. Functional groups of the polymeric polymers can chelate with silver ions and be stably compatible with water or organic solvents, whereby the silver nanoparticles can be stably dispersed without aggregation and the produced silver nanoparticles.

    Abstract: A phosphorous flame retardant primarily includes hexachlorotriphosphazene (HCP) having poly(oxyalkylene)amine substitutes. The poly(oxyalkylene)amine includes at least two end groups. The phosphorous flame retardant can further include layered silicate clay. The layered silicate clay can be intercalated and modified with the poly(oxyalkylene)amine substitutes of HCP to effectively promote thermal stability. The flame retardant, phosphazene-poly(oxyalkylene)amine adducts, can be applied to a polymer. By the cross-linking between them, the flame-retarding property of the polymer can be improved. Also provided is a method for producing the flame retardant of phosphazene-poly(oxyalkylene)amine adducts and application thereof to a polymer.

    Abstract: A CNT-PI complex primarily includes polyimide (PI) and carbon nanotubes (CNT) dispersed in the polyimide. The method for producing the CNT-PI complex first disperses carbon nanotubes in a solvent by adding a dispersant and using an ultrasonic oscillator. Then the carbon nanotubes dispersion is mixed with polyamic acid to give a CNT-PI dispersion. The CNT-PI dispersion is then dried to form a film or layer of the CNT-PI complex. The dispersant used in this invention is an ionic liquid including organic cations and inorganic anions. The produced CNT-PI complex possesses good electromagnetic shielding effectiveness and presents better networked structures and electrical conductivity.
