| Abstract: |
| To study on effective protective coating measures and retard aging of Vectran fibers under high photoirradiation, the benzotriazole absorber, triazine absorber, and hindered amine light stabilizer were used to mix with the OH terminated hyperbranched polyester-modified TiO2 to prepare coatings on fibers by ultrasonic impregnation. The complex coatings were studied by scanning electron microscope, transmission electron microscope, filament tensile test, ultraviolet transmission spectrum and adhesion test. The ultrasonic impregnation method could effectively improve the adhesion between the complex coating and the fiber. The complex coating could guarantee the zero ultraviolet transmittance in 200-380 nm. The retention strength of complex coating fiber after 336 h of light irradiation increased by 49% compared with the uncoated fiber.The inorganic/organic complex coating greatly reduces the damage of fiber under photoirradiation, and slows degradation of Vectran fibers effectively. It can improve the UV resistance of Vectran fiber in the stratosphere and extend its service life as the reinforced material of stratospheric airship envelope. |
