关键字：Hyperbranched polyurethane Waterborne sizing agent UV-resistance Interfacial properties

摘要：In this study, a novel UV-resistant hyperbranched polyurethane (HBPU) was designed and processed into a series of waterborne sizing agents for short carbon fiber (SCF). The content of functional groups on the SCF surface was subsequently increased, leading to improvement of the interfacial adhesion of SCF/polyamide6 (PA6) composites. According to the mechanical property results, SCF/PA6 composites with 0.5 wt% sizing agent showed the best reinforcing effect, with the tensile and bending strength increased by 41.4% and 26.4%, respectively. The mechanisms for the enhancement of the interfacial adhesion by sizing agent were investigated. Noteworthy, the mechanical properties of the sizing SCF/PA6 composites remained about 99% after a week of uninterrupted UV aging treatment, indicating the excellent UV resistance of the nTiO2 grafted HBPU sizing agent.
