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 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 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.
