PAMAM as "the fourth class of new polymer materials", are attractive to the scientific world and industrial circles. The novelty of these materials includes highly branched molecular structure, a large number of surface functional groups, void space in molecules, monodisperse molecular weight distribution and nanoscale dimensions. The structural characteristics of PAMAM lead to unique properties such as excellent solubility and dispersion properties, low melt viscosity and solution viscosity, difficult to crystallize and easy to form film, showing unparalleled nano features.
