I prepared CNT + TiO2 composites via sol gel method . then calcinated at 75 C . it showed some layered structure as shown in figure . I need comments from experts on this .
That's not uncommon. The sol-gel dynamics are seemingly putting an ordering and the liquid crystal behavior is most probably leading to this situation. The inherent crystallinity of the material TiO2 and carbon nanotube quality/purity are playing the part.
