摘要:
The present invention provides a method for inhibiting microorganisms or plant pests using exfoliated clay/surfactant complex. The weight ratio of the exfoliated clay to the surfactant can range from 99/1 to 1/99. Preferably, the exfoliated clay is an inorganic layered clay on a nano scale and the surfactant is cationic, nonionic, anionic or amphoteric.

The present invention provides an organic/inorganic compositive dispersant and a method for producing the same. The compositive dispersant comprises a complex of inorganic clay and an organic surfactant. The compositive dispersant is produced by reacting inorganic clay with the organic surfactant in a solvent to generate a complex. The inorganic clay is layered or platelet. The organic surfactant is an anionic surfactant such as alkyl sulfates, or a nonionic surfactant such as octylphenol polyethoxylate and polyoxyethylene alkyl ether. The compositive dispersant may be used to produce electrolytes of a solar cell or to increase the hardness of an epoxy resin.

摘要:
A method of synthesizing size-controllable metal nanoparticles includes the following steps: a) Preparing an exfoliated silicate clay solution and a metal ion solution; and b) Mixing the exfoliated silicate clay solution with the metal ion solution, and the metal ions are reduced to the metal nanoparticles, which are attached to the exfoliated silicate clays. Additionally, in step A, adjust the weight ratio of the silicate clays to the metal ions to control the size of the reduced metal particles. And with larger weight ratio of the silicate clays to the metal ions, the size of the reduced metal particles becomes smaller.

The present invention provides a macromolecular dispersant and a synthesis method thereof, and the dispersant is synthesized by reacting polyisobutylene-g-succinic anhydride with amine compounds. In addition, the present invention also provides an oil-soluble dispersant composition with nano particle pigments and the manufacturing method thereof. The oil-soluble dispersant composition is manufactured by milling a macromolecular dispersant with a pigment and a grinding media. The oil-soluble dispersant composition is adequate for various pigments, shows the excellent immiscibility of oil/water interface, and owns the low viscosity of ≦4 cps and the optical density of ink ≧1.1. Therefore, the oil-soluble dispersant of the present invention for the nano particle pigment can be acted as the material of the electrowetting display.

摘要:
The present invention provides a method of using a composite of spherical silver nanoparticles and layered inorganic clay, in particular nanosilicate platelets, for inhibiting the growth of silver-resistant bacteria. The layered inorganic clay serves as carriers of the silver nanoparticles and disperses them. The composite has a particle size of about 5 nm to 100 nm. The silver nanoparticles can be dispersed in an organic solvent or water.

The present invention provides a method for controlling toxicity of metallic particles and a low-toxicity composite of metallic nanoparticles and inorganic clay. The metallic nanoparticles are effective in preventing infection and in skinning over, and thus suitable for treating scalds/burns. In the composite, the weight ratio of metallic nanoparticles to inorganic clay preferably ranges 0.1/99.9 to 6.0/94.0 in a size of about 5 to 100 nm. Preferably, the metal is silver and the inorganic clay is nanosilicate platelets.
