| 제목 | Preparation and Characterization of Poly (Ethylene Terephthalate) (PET) Nanocomposites with Exfoliated structure: Tensile Mechanical Properties |
| 초록 | Polymer/clay nanocomposites have attracted much attention both in academia and industry because they show significant improvements in moduli, strength and thermal resistance, gas barrier property and fire retardance when compared to virgin polymers or conventional microcomposites. Poly (ethylene terephthalate) (PET) is a large volume plastic that has been used for fibers, bottles, films, and engineering plastics for many years. This wide range of applications of PET can be even more extended by incorporation of clay into PET matrix. In our previous study, we successfully prepared new organoclays (BrEthPC and BrEthNC) compatible with PET. TGA results clearly show that the BrEthPC and BrEthNC show significantly enhanced thermal stability compared to that of commercially available organoclays (15A and 30B). It is also observed that the synthesized organoclays are completely exfoliated by melt-mixing with PET. In this study, we report tensile properties of these PET nanocomposites (PET/BrEthPC and PET/BrEthNC). Tensile strength, elongation at break and Young's modulus are measured using a Lloyd LR 10K universal test. From these tensile test for the PET nanocomposites, it is found that the PET/BrEthNC shows higher tensile strength and Young's modulus than neat PET with 1 wt% of loading of BrEthNC. Fig. 1.
