Dendrimers (CYD-CD215/CYD-CD151) can be immobilized onto gold, silica, quartz and other polymeric materials by physical or chemical method to improve application performance of materials that is applied to optical materials, sensors, etc., such as being immobilized onto the PP substrate to improve the material resistant to air permeability, adhesion, fluoride etc., resistance to air permeability can be increased by 16.6 times, and has good adhesion performance, can withstand force by 20N /cm2 . Conversely,adding dendrimers to coatings or other materials to improve adhesion property on gold, silica, or other materials. Weihai CY Dendrimer Technology Co. Ltd.-Professional Manufacturer for low cost dendritic polymers.
