Polyurethane/zinc borate (PU/ZB) nanocomposites were prepared via in situ polymerization with the main aim to increase the flame retardancy of PU. In this study, zinc borate (ZB) nanoparticles were modified with poly (propylene glycol) phosphate ester (PPG-P) and oleic acid (OA). The surface modification of ZB, the microstructure and the properties of nanocomposites were investigated by water contact...
In this study, in order to improve the dispersion and increase the compatibility between nanoparticles and waterborne polyurethane (WPU) matrix, CaCO 3 nanoparticles were firstly modified with oleic acid (OA). A series of WPU/CaCO 3 nanocomposites were prepared by further in situ polymerization. SEM examination of the fractured surfaces of nanocomposites showed that OA–CaCO 3 ...
