Incorporation of TiO2 nanoparticles onto carbon nanotube fibers enhances their thermal stability and structural integrity, resulting in sustainable mechanical and electrical properties as well as high photocatalytic activity under UV exposure. This demonstrates that the incorporation of TiO2 NPs is an efficient strategy to improve the long-term stability and applicability of CNTFs.
UV resistant and photocatalytic TiO2/carbon nanotube nanohybrid (TiO2@CNT) fibers are developed by incorporation of TiO2 nanoparticles (NPs) onto CNT fibers (CNTFs). This process densifies the CNTFs, and increases the thermal stability and structural integrity of the resulting TiO2@CNTFs under UV exposure. As a result, the TiO2@CNTFs have mechanical and electrical properties that are more sustainable than those of pristine CNTFs under exposure to strong UV light, and have high and recyclable photocatalytic activity for degradation of organic dyes. These results indicate that incorporation of TiO2 NPs is an efficient strategy to increased long-term stability and applicability of CNTFs.
