    Abstract: The present invention provides a method for collecting oil with a modified clay. By mixing the modified clay and oil, the oil can be adsorbed to the clay. The modified clay is obtained by intercalating a hydrophobic polymer such as acidified poly(oxyalkylene)-amine into layered silicate clay, mica or talc to enlarge the interlayer space. The modified clay thus becomes hydrophobic and adsorption to the oil is promoted.

    Abstract: The present invention discloses an inorganic/organic mixed component (I/O) dispersant and applications thereof, which is primarily applied to dispersing nanoparticles of metal oxides. The I/O dispersant of the present invention can be a composite of inorganic clay and an organic surfactant, a composite of inorganic clay and polyoxyalkylene-amine, or a composite of inorganic clay, polyisobutylene succinic anhydride (PIB-SA) and hydrochloric acid salt or tetraalkyl quaternary salt of polyoxyalkylene-amine, or fatty amines. By mixing with the I/O dispersant of the present invention, nanoparticles of a metal oxide can be uniformly dispersed without aggregation particularly at high solid content. The dispersion has a lower viscosity and is relatively stable in storage even at high temperature.

    Abstract: The present invention discloses a polymeric polyamine which can be produced by polymerizing polyoxyalkylene-amine and a linker. The linker can be anhydride, carboxylic acid, epoxy, isocyanate or poly(styrene-co-maleic anhydride) copolymers (SMA). The present invention also discloses a method for stabilizing the Ag nanoparticles with polymeric polyamine. The polymeric polyamine serving as a stabilizer or dispersant is mixed with a water solution of silver salt and then a reducer is provided to reduce the silver ions and form an organic or a water solution of Ag nanoparticles. Water or solvent of this solution can be further removed through a heating, freezing or decompression process, and thus solid content of the solution can be increased. The concentrated solution also can be diluted to obtain a stable dispersion without aggregation.

    Abstract: The present invention discloses a method for producing a clay/AMO complex by modifying layered inorganic silicate clay with the intercalating agent AMO (amine-terminated Mannich oligomer). The AMO is prepared by polymerizing polyoxyalkylene amine having molecular weight over 1000, p-cresol and formaldehyde. The present invention also discloses a method for producing nanosilicate plates by extracting the AMO from the above complex with a hydroxide or a chloride of alkali metal or alkaline-earth metal. The extracted AMO can be recycled for reusing.
