Preparation of hydroxyl and (3‐aminopropyl)triethoxysilane functionalized multiwall carbon nanotubes for use as conductive fillers in the polyurethane composite

A new method has been developed to prepare hydroxyl‐functionalized multiwall carbon nanotubes (MWCNTs‐OH) and (3‐aminopropyl)triethoxysilane‐functionalized MWCNTs (MWCNTs‐APTES), which can be uniformly dispersed in solvent‐borne polyurethane (PU) to obtain the nanocomposites with enhanced mechanical, thermal, and electrical properties.
