Dendritic acrylic polyurethane nanocomposite has good performance in coating application.
Mechanical properties, water resistance, solvent resistance of nanocomposite is not ideal due to small functionality of the preparation material conventional linear acrylic polyurethane. Dendritic polymer was used to prepare high functionality acrylic polyurethane systems, obtained acrylic polyurethane/inorganic nanocomposite with high performance, the adhesion reached 0 class, which was enhanced 4 classes than conventional systems, the hardness improved from 2B to 4H, and flexibility was greatly increased, meanwhile, the dendrimer based coating has double bond.
Dosage of inorganic oxide was 1% -5%, added 1 wt% photoinitiator named Runtecure 1103, mixed 15 min without light, coated on glass, dried at 50 ℃ in vacuo, and irradiated with UV light to obtain films. The new film has following properties: gloss, adhesion, hardness, anti-stoning, flexibility, weather resistance, solvent resistance, chemical resistance.

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.

Effective application of dendritic polymers in protective substrates.
In order to prevent metal pipe, pipe connections and pipelines from corroding, mechanical damage caused by friction or degradation due to exposure to the sun, soil, moisture etc, protective coating can be coated. Dendrimer based curable compound is particularly good at providing anti-cathode degumming performance, thus protecting the pipes. When it’s not cured, provides excellent adhesion to substrates.

Carboxyl terminated dendrimer based aluminum tanning agent without chrome.
As people’s awareness of environmental protection, negative effects of chrome tanning can’t be ignored any more, therefore, the production of little chrome, no chrome tanning agents is more important for industry. Carboxyl terminated dendritic tanning agents overcome aluminum tanning agent disadvantages that not washable, low shrinkage temperature, and have great retanning effect, is a new kind of multi-tanning agent. Dendritic polymers have hyperbranched structures and lots of end groups, can form crosslinks with aluminum and dermomyotome with retanning effect, increasing thick rate was increased by 25.10% than ordinary aluminum tanning agent. While the leather tear strength was improved 12.69% and tensile strength 11.28%, and the specific performance of tanning agents can effectively disperse the fiber bundle, so that leather surface was full soft.

Effective application of dendrimers in the field of ultra-low pressure reverse osmosis membrane.
Dendrimer-based ultra-low pressure reverse osmosis membrane can effectively retain a variety of salts, such as sodium sulfate, sodium chloride, magnesium sulfate, retention rate reaches 92%, in particular sodium sulphate, up to 98%. The membrane has high flux, and low operating pressure. Water flux can reach 30-40 L • M-2 • h - 1, operating pressure was 0.6MPa. The film has good resistance to chlorine, acid and alkali resistance is little weaker. In addition, the membrane has excellent separation performance for PEG-200, showing its promising application in separation small organic molecules from the water.
