Abstract
In the presented study, 3,5-diamino-N-(4-methyl-1-oxo-1-(phenylamino)pentan-2-yl)benzamide (V) as a new diamine monomer is synthesized and fully characterized by means of FT-IR, 1H-NMR, 13C-NMR, and elemental analysis techniques. The stated diamine is used for the sol–gel fabrication of a series of polyimide (PI)/titania nanohybrid films with various titania percentages. The special design of diamine monomer containing bulky pendant group increased the flexibility of resulted PI matrixes. On the other hand, the ability to construct strong organic/inorganic H-bond lattice has led to the effective surrounding of nanoparticles by PI grounds and thus the well-dispersed quite spherical nanoparticles were created via a sol–gel procedure. The obtained nanocomposites showed high thermal stability and UV–vis absorption efficiency. The X-ray diffraction experiments confirmed the titania nanoparticles to be amorphous.
