Pd nano-size is 1.56+/-0.67nm in catalyst SiO2@Pd-PAMAM, so it has a superior performance in the hydrogenation reaction as catalyst. It can effectively catalyze olefins, alkynes, ketones, nitro etc in hydrogenation reaction with a conversion rate of 100%, and 100% selectivity, compared with the traditional Pa catalyst, the catalytic performance is doubled. In addition ,SiO2@ Pd-PAMAM catalyst can be repeated using five times to maintain the original catalytic efficiency, almost no exudation of Pd and mingled with reactants, and traditional Pa catalyst cycled three times will lose its catalytic properties.

G0 generation PAMAM can react with diisocyanate to make polyurea micro-spherical shell, and the linseed oil coated by polyurea microspheres through emulsification compounds with polyurethane substrate to get coating with self-healing properties. Such coatings can improve its thermal stability up to
380 °C. Polyurea microspheres with a large number of amino group can improve its adhesion performance with polyurethane coating or substrate. The polyurea microspheres based on PAMAM embedded in the polyurethane coatings to coat on the surface of the steel material, its antiseptic properties will be improved with the content increase of polyurea microspheres in the polyurethane coatings, the general content is between 2-5%. When the content is 5%, it shows the best corrosion resistance, even rupturing 120h will still have a good self-healing properties.

5-fluorouracil (5FU) has significant anti-tumor activity, but it has a higher toxic side effects. PAMAM and 5-fluorouracil combine together to form dendrimer-5FU conjugates and release toxicity of 5FU. Thus better for the the anti-tumor drugs carrier. The fluorinated dendrimer is soluble in supercritical CO2, strongly hydrophilic compounds can be extracted from the water to the liquid CO2. Thus in industry, the liquid CO2 replaces harmful organic solvents. Weihai CY Dendrimer Technology Co.
