Application of dendritic demulsifer in oil field.

Application of dendritic demulsifer in oil field.

Dendrimer based new demulsifer has good surface properties and infiltrability, it can quickly reach oil-water interface to replace active substances to form new film; due to special structure of dendritic polymers, molecules of the newly formed films are difficult to approach each other, and weaken Waals forces to lower film strength and promote separation of water and oil.

The excellent properties of dendrimer modified silver bromide nanoparticles in light catalysis.

 

The excellent properties of dendrimer modified silver bromide nanoparticles in light catalysis.

Dendrimers are used as template to prepare sliver bromide nanoparticles, the sliver bromide are encapsulated in dendrimer, and nanoparticles were narrowly distributed with good stability. By adjusting proportion of Ag+ and dendrimer, silver bromide nanoparticles with different particles size were obtained. The sliver bromide and dendrimer nanocomposites are good at photocatalytic degradation of methyl orange, the smaller size, the better catalytic ability.

Excellent properties of dendrimer in Nano metal ions.

Excellent properties of dendrimer in Nano metal ions.

Preparation of size and shape controllable metal clusters is a challenge to Nanomaterial Science.

Dispersed and fine dendritic polymers are used as templates, size, stability, solubility of nano particles are controllable. So dendrimers are appropriate temperate for Nano metal particles due to void space and surface groups. Dendrimers are used as templates and sodium borohydride are used as reducer to react with samarium, particles with average size 4.7 nm±0.5 nm and uniform distribution can be obtained. Generations of dendrimers decide its possibility in reaction as templates, high generation dendrimers are more suitable to be used as template and stabilizer.
