摘要：

In the present work, the third generation hyperbranched polyester (HBPE-3G) based polyurethane acrylate (HBPUA-32)/ZnO hybrid coatings are prepared, by modifying 16 hydroxyl groups of HBPE-3G with an acrylic adduct. The HBPE-32 is prepared from the di-trimethylol propane and 2,2-bis(hydroxymethyl) propionic acid, converted into hybrid coatings by incorporating 1%, 3% and 5% nano ZnO powder into the polymer matrix. The H-1, C-13 NMR and FT-IR spectroscopy methods are used for structural characterization, degree of branching calculation and structure to property correlation study and various hybrid film properties are analyzed by TGA, DMTA, XRD and SEM instruments.
