- Abstract
The self-assembly of an amido-ended hydrophilic hyperbranched polyester (HTDA-2) into ordered, compact, 2D, tree-like structures with a diameter of over 500 μm and a trunk-width of about 3-5 μm by the induction effect of cupric ions is presented. Influencing factors on the morphology of the self-assemblies, including temperature, time, solvents, concentration, and humidity, investigated by polarizing optical microscopy (POM) and scanning electron microscopy (SEM), are discussed. The self-assembly mechanism is analyzed by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), SEM, and Fourier transform IR (FTIR) spectroscopy. A dimension ( Df) of about 1.50 for the perfect fractal behavior and the crystal behavior of the self-assemblies are determined.
