Study on the properties of polydopamine/hexadecyltrimethoxysilane co‐deposition functionalized modified graphene oxide and composite styrene–butadiene–styrene modified asphalt binder
Abstract:A composite graphene oxide (GO) modifier was prepared by co‐deposition of polydopamine (PDA) and hexadecyltrimethoxysilane (HDTMS) with hydrophobic function to enhance the interfacial interaction between GO and asphalt. Dopamine as a medium enhances the adhesion of the hydrophobic functional material HDTMS on the surface of GO. And the long alkyl chains of HDTMS molecules greatly reduce the surface free energy and ensure the dispersion stability of composite GO modifier in styrene–butadiene–styrene (SBS) modif… Show more
