چکیده مقاله :
Porous organic polymers are a new class of nanoporous materials that have been discovered in recent decades. Due to their very porous nature and covalent bond structures, they have a wide surface area and high stability. These properties make them useful in a number of advanced practical applications [1]. Covalent triazine polymers (CTPs) are a new class of porous organic polymers that contain aromatic triazine units with π-bonding properties. CTP frameworks are useful for application in gas adsorption/separation and catalysis, photocatalyst, Lithium-ion batteries, luminance and pollutant removal. CTPs have high thermal stability, and also show high stability in the presence of strong acids and bases [2], which makes them superior to other porous materials and has a strong potential for use in industrial applications. In this study, we report the synthesis and characterization of melamine-based CTPs using 1,3,5-Triazine-2,4,6-triamine and dicarboxylic acids under different reaction conditions such as various molar ratios of initial materials, different reaction temperature and solvent by catalyst free polycondensation via solvothermal method. The structure of the synthesized melamine-based CTPs was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), thermaogravimetric analysis (TGA) and X-ray diffraction (XRD). The porosity analyses were also done via BET measurements. Furthermore, the effect of different synthesis conditions on the porosity, thermal stability, solubility and crystallinity of the prepared CTP was examined.
