Synthesis and characterization of dendritic poly(amidoamine)-silica gel hybrids

Novel dendrimer-silica gel hybrids were prepared from amino-terminated poly(amidoamine) generation 3 (32 cascade) and its partly ester-terminated derivatives with tetraethoxysilane in the presence of a coupling agent 3-glycidoxypropyltrimethoxysilane by in situ sol-gel process. The scanning electron micrograph spectra showed that these transparent hybrids have the nanocomposite structure. Their transparent and thermal properties were characterized by ultraviolet, thermogravimetric analysis. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 78: 2186–2190, 2000
