Effective application of dendrimers in calcium alginate fiber dyeing.

Effective application of dendrimers in calcium alginate fiber dyeing.
With the increase of dendrimer generation, dye effect on calcium alginate fibers was gradually increased, dyeing rate reached 43% when dendrimer was the fourth generation.The modified calcium alginate fiber has higher K/S values for reactive dyes. Dendrimer modified calcium alginate fibers washed four times in 40 ℃ distilled water, K/S value reached the stable value, the loss rate of K/S values was about 4%, which indicates that fiber sample has high water resistance fastness.

Effective application of

Effective application of dendrimers in nanofiltration.
Problems of current polysulfone nanofiltration membrane material: high operating pressure (> 016 MPa), high energy consumption, low throughput, poor anti-pollution ability. The improvement would be reduce permeable membrane stress, increase water flux and salt rejection rate, enhance anti-pollution ability. Current polymer nanofiltration membrane: homogeneous membrane and composite membrane, and the second is widely used, this film is based on microporous membrane, the composite layer has ultra-thin surface with nanoscale aperture, which determines separation and permeability of nanofiltration membrane. Dendrimers can significantly improve the performance of nanofiltration membranes: highly branched molecules, large free volume, many internal molecular nanoscale holes. Dendrimer used as nanofiltration membrane selective layer, can reduce operating pressure, improve membrane flux.

Application of dendrimers in water based coatings.
Society now pay more attention to environment protection, water based coatings become focus of researchers. Dendritic dispersants overcome disadvantages of inorganic and organic dispersant, such as impurity ions bringing, not strongly adsorbed, less dispersion stability etc., so now have been used widely in coating, ink, dyeing, plastic filling, ceramic dispersion, cement dispersing, soft magnetic materials etc. Dendritic dispersants are remarkable in dispersant. They have following advantages in water based coating: (1) wetting and dispersing quickly, good stability (2) dispersing pigments uniformly, improve adhesion, covering power, gloss and leveling, avoid flooding and floating occur when mixing various colored paint (3) apparently decrease viscosity of the system and reached minimum viscosity under appropriate dosage. It can improve fluidity to be easier to operate and lower energy consumption (4) decrease production and operation cost.

Application of dendrimer in

Application of dendrimer in ion exchange resin and chelating resin.
Ion exchange resin has been widely used in water treatment, such as softening salt water, dealkalization, demineralization, condensate polishing and removal of nitrates, disposal of radioactive waste water, heavy metal recycling and washing water reuse. Ion exchange resin is not ideal to selectively remove heavy metal ions in alkali metal solution. Dendritic chelating resin can refine metal ions from liquid without changing main resin structure.

Effective application of dendrimers in dye industry.
1) dendrimers have good performance in promoting cotton fiber dyeing of reactive dyes. After pretreatment of dendrimers, reactive dye dying degree of cotton fabric can be significantly improved, even coloring without strong base and electrolyte. Pretreatment by dendrimers can save a lot of strong base and electrolytes, and unreacted dyes can be recycled. 2) the unique structure and properties of dendrimers shows a good prospect in treating wastewater containing dye. Dendrimers as an efficient decolorization flocculant, has the characteristics of less dosage, wide pH applicable range, high decolorization rate, easy to operate, treated water reusable for high concentrations of dye wastewater with high chroma. For some dye wastewater, decolorization rate can be 98%, COD removal rate could reach 96%, therefore, dendrimers will have a good application prospects in dye wastewater treatment.

Dendritic nano catalysts can

Dendritic nano catalysts can greatly enhance the catalytic activity of the push agent.
Nanoparticles prepared by the dendritic template has uniform size, as catalyst can significantly improve the catalytic activity of the push agent. Dendrimer on the surface of nanoparticles is curled state in air or poor solvents, while it’s non-curled state in good solvents such as alcohols,it’s stretched state, thus affecting the performance. Dendrimers-OH was used as template to prepare Pt nanoparticles, in the gas phase it doesn’t adsorb carbon monoxide. While in ethanol, the adsorption amount was significantly increased, substantially saturated after 1 hour adsorption.

Dendrimers as drug carriers

Dendrimers as drug carriers have excellent targeting property.
Dendrimers as drug carriers have good performance as its unique cavity structure and a lot of end groups, such as adequate drug loading, long-term cycle, better drug targeting, drug release controllability, and little or no toxicity. Anticancer drug loaded by dendrimers has good targeting and long-term retention, it has stronger vascular permeability to lesions, but in normal tissues has weak permeability, even in normal tissues will loop out and enter into the diseased tissue again. Drug can be loaded onto dendrimer in two ways. Non-covalent interaction, hydrogen bonding, hydrophobic interactions, ion electrostatic interaction; covalent interaction, including graft drug on the surface of dendrimer by chemical reaction. Dendrimers have been used as drug carriers for methylamine purine, paclitaxel, fluorouracil anticancer drugs in vivo animal experiments, have good load targeting.
