Synthesis of polyaniline on functionalized TiO2 using two-container type in situ coating technique
The possibility of coating polyaniline molecules onto functionalized TiO2 particles was explored using two-container type in situ coating technique. The TiO2 particles were functionalized by silane–aniline molecules as linker between the TiO2 and polyaniline molecules. The precursor and oxidizing agent were placed in two separate containers during polymerization to minimize aggregation of polyaniline molecules in the bulk of the solution. Peaks detected from the infrared spectra possess the vibrational peaks associated with the synthesized polyaniline molecules coating onto the silane–aniline functionalized TiO2. A possible configuration was constructed to illustrate the coexistence of different structures as a result of the synthesized polyaniline molecules onto the functionalized TiO2 surface. Morphology of the samples using SEM with EDX mapping shows the uniform distribution of Ti and Si atoms throughout the sample. By utilizing the two-container type in situ coating technique, polyaniline molecules were successfully coated onto the surface of TiO2 particles using silane–aniline as coupling agent. |
