Description
Abstract
In this work, a series of polymer nanocomposites (AAS/KS) of acrylamide (AM)/ acrylic acid (AA)/ sodium p-styrenesulfonate (SSS)/ 3-Methacryloxypropyltrimethoxysilane (KH570) modified nano-silica were successfully synthesized via in situ polymerization. The 1H nuclear magnetic resonance spectroscopy (1H NMR) confirmed the successful synthesis of AAS/KS, the morphology of KH570 modified nano-silica (KS) and AAS/KS polymer nanocomposites were observed by scanning electron microscope (SEM) ...
