Properties of PET Containing Epoxy-Functionalized Polyhedral Oligomeric Silsesquioxane |
| 초록 |
Poly(ethylene terephthalate) (PET) containing epoxy-functionalized polyhedral oligomeric silsesquioxane (POSS) was prepared by melt-mixing and in-situ polymerization methods. The melt-mixed composite showed phase separation while the in-situ polymerized composite did not based on SEM characterization. During melt mixing, the reaction between the epoxy groups of POSS and hydroxyl groups of PET occurred, based on DSC results. DSC results on the in-situ polymerization product showed formation of a lower melting component compared to PET. The tensile strength and modulus of the melt-mixed composite fiber decreased compared to those of PET, whereas those of the in-situ polymerized composite showed slightly higher values compared to PET despite the use of relatively small amounts (1 wt%) of POSS were used. Dynamic mechanical analysis results showed an increase in storage modulus for the in-situ polymerized composite of POSS and PET compared to PET over the temperature range of 40ºC to 140ºC. |
