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

摘要

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. (C) 2000 John Wiley & Sons, Inc. [References: 19]
