| Özet |
| In the current study, naturally occurring halloysite nanotube (HNT) is first modified by vinyltriethoxysilane to obtain vinyl-functionalized HNT (HNT-Vinyl). Subsequently, the HNT-Vinyl is added as nanofiller by varying weight from 0 to 8% in the presence of multifunctional methacrylates (bisphenol A-dimethacrylate and triethylene glycol dimethacrylate). Free radical photocrosslinking polymerization of these materials provides the in-situ formation of HNT/thermoset nanocomposites. Comparison of characteristic bands of the nanocomposite components by Fourier transform infrared spectroscopy confirms the presence and covalent bonding of HNT nanofiller in the thermoset matrix. Thermal properties of obtained HNT/thermoset nanocomposites have been compared with neat thermoset as a reference sample using thermogravimetric analysis. Moreover, the existence and dispersion of nanofillers in the nanocomposites have been proved by scanning electron microscopy and transmission electron microscopy. The HNT nanofiller has been detected as agglomerated/non-agglomerated morphology in the thermoset matrix. On the other hand, the addition of HNT-Vinyl to the thermoset matrix has improved the mechanical properties of nanocomposites. Especially, a dramatic increase on tensile strength values has been determined with 4% HNT-Vinyl loading. Tensile strength and elastic modulus values of the corresponding nanocomposite are 4.9 and 1.5 times higher than those of the neat thermoset. |
