ABSTRACT

Composites consisting of carbopol (CP) and ceramic titanium dioxide nanoparticles, TiO₂ have been investigated. The CP-TiO₂, organic-inorganic hybrid composites have been prepared in DMF by heating the mixture with a constant rate of 1^。C/min, up to 30^。C, 45^。C, 60^。C, 80^。C, 100^。C and 120^。C. Proprieties such as absorption, structure and external aspect of the obtained materials were investigated by Uv-vis, FTIR, DRX and SEM analyses. The X-ray diffraction patterns confirmed that the TiO₂ nanoparticles maintained their original tetragonal anatase-type crystalline structure in the composites. The chemical structure of theobtained materials was determined by ATR-FTIR spectroscopy. The influence of TiO₂ nanoparticles on the thermal proprieties of carbopol matrix was investigated using thermo-gravimetric analysis and differential scanning calorimetry. The glass transition temperature (Tg) of the carbopol matrix was considerably increased by the presence of ceramic feller nanoparticles and its thermal stability was significantly improved. Furthermore the water loss which represents 7.56% of the weight loss in pure CP at 100^。C was avoided in the CP-TiO₂ nanocomposites at this same temperature. This important finding revealed that ceramic fellers blocked the water loss in the modified carbopol nanocomposites, which stayed stable till 200^。C.
