| Abstract | In order to improve the mechanical properties of epoxy resin(EP), TiO2 hollow multi-shelled structures (HoMSs) were synthesized by sequential templating approach, and then coupling agents were used to graft the obtained HoMSs. After that, the modified TiO2 HoMSs were filled into the EP to prepare TiO2 HoMSs/EP composites, which were compared with single-shelled TiO2/EP composites. The effects of shell number and coupling agent modification on the mechanical properties of the composites were studied. It is demonstrated that the mechanical properties of the composites increase as the number of shells increases, and can be further improved by modifying TiO2 HoMSs with coupling agents. The tensile strength, elongation at break and impact strength of silane coupling agent KH-560 modified triple-shelled TiO2 HoMSs/EP composites can reach 71.66 MPa, 7.4% and 35.81 kJ/m(2), respectively. Scanning electron microscopy(SEM) images exhibit that the TiO2 HoMSs/EP composites possess the rougher cross section than that of pure EP, which illustrates that HoMSs can absorb the external stress and hinder the crack propagation to improve the toughness of the composites and enhance the impact strength of the composites. |
