Nitrogen-doped TiO2/PTFE with unique characteristic and photocatalytic self cleaning activity under visible light were successfully produced using a modified solvothermal method with urea as the nitrogen source. This study combines photocatalyst of inorganic materials (TiO2) with superhydrophobic polymers (PTFE) for self cleaning glass coating. The X-Ray Diffraction show that the composite crystalline and new peak formed as indicated of PTFE. FTIR showed the presence of C-F groups on N doped TiO2, which showed the composite had successfully formed. The morphology by scanning electron microscopy showed that agglomeration formed from N doped TiO2/PTFE. The composite coatings showed a contact angle of 111.4 °. The results confirm that the synthesized TiO2 were successfully doped with nitrogen and composite with PTFE, allowing a higher photocatalytic activity. The composite N doped TiO2/PTFE has competely coated on a glass substrate and enable to degrade methylene blue up to 79.9% for 1 hour irradiation.
