Preparation and properties of nano-titanium dioxide/epoxidation deproteinized natural rubber latex composites
Polydopamine (PDA) modified nano-TiO2 (PTiO2)/epoxidized natural rubber (ENR) composite films were prepared by latex blending method using ENR with epoxy degree of 25% as matrix and PTiO2 as filler, and the effects of the addition amount of the filler PTiO2 on the mechanical properties, thermal stab...

| description | Polydopamine (PDA) modified nano-TiO2 (PTiO2)/epoxidized natural rubber (ENR) composite films were prepared by latex blending method using ENR with epoxy degree of 25% as matrix and PTiO2 as filler, and the effects of the addition amount of the filler PTiO2 on the mechanical properties, thermal stability and anti-ultraviolet aging performance of PTiO2/ENR composite films were studied. The results showed that PDA improved the dispersion of nano-TiO2 in ENR matrix. After the addition of the filler PTiO2, the thermal stability of PTiO2/ENR composite film increased gradually, and when the addition amount of PTiO2 was 5 phr (mass), the tensile strength of PTiO2/ENR composite film was 8.15 MPa, which increased by 2.8 times compared with that of ENR，and the elongation at break was 1 141%. The retention rate of mechanical properties after ultraviolet irradiation were more than 97%, which indicated that PTiO2/ENR composite film had better anti-ultraviolet aging performance.
