Effect of Surface modification on Thermal stability in Poly(ethylene terephthalate)/ Calcium carbonate nanocomposites. |
| 초록 |
The previous works on thermal stability of polymer nanocomposite materials were interested in homogeneous dispersion, filler type and content. In this work, influence of surface modification on thermal stability in Poly(ethylene terephthalate)/ Calcium carbonate nanocomposites was investigated. Two types of surface modification of both PET and CaCO3 were used, in order to improve thermal stability. One type was modified for hydrophobic surface, other type was modified for hydrophilic surface. PET/CaCO3 nanocomposites were prepared by twin extruder. To analyze thermal property of PET/CaCO3 nanocomposites, we have performed DSC, TGA, TMA test. Therefore, PET/CaCO3 nanocomposites were improved thermal stability than plain PET. Especially PET/CaCO3 nanocomposites prepared by hydrophilic modification were improved thermal stability than hydrophobic modification. |
