Polyamide-imide from Toluic Acid Derivatives

Preparation and Characterization of Silica/Polyamide-imide Nanocomposite Thin Films

The functional silica/polyamide-imide composite films were prepared via simple ultrasonic blending, after the silica nanoparticles were modified by cationic surfactant-cetyltrimethyl ammonium bromide (CTAB). The composite films were characterized by scanning electron microscope (SEM), thermo gravimetric analysis (TGA) and thermomechanical analysis (TMA). CTAB-modified silica nanoparticles were ...

In Based on Amino Acid Compounds Synthesis of New Poly(Ester-Imide)s and Poly(Imide-Urethane)s Derivatives

20 new poly(ester-imide)s and poly(imide-urethane)s structures were synthesized using low temperature solution condensation polymerization. These compounds were optically active, capable of emitting circularly polarized light. The results indicated that the efficiency of the compounds much higher under this synthesis method. Cost effectiveness and short process were other advantages of this syn...

Synthesis and Characterisation of Silica/Polyamide-Imide Composite Film for Enamel Wire

Hydrogen gas sensor based upon perylene-imide derivatives

Perylene-imide derivatives are industrially important pigments that exhibit a variety of shades from red via maroon to black. In the present investigation, we have synthesized novel perylene-imide derivatives with pyridyl rings in an attempt to apply them for H2 gas sensors based upon proton acceptors. The two N atoms of the pyridyl rings which work as proton acceptors are found to remain unbon...
