Polypropylene/Poly(trimethylene terephthalate) Blend Nanocomposite: A Thermal Properties Study

摘要

In this article, thermal properties of polypropylene/poly(trimethylene terephthalate) melt-mixed blends containing organically modified montmorillonite nanoclays and interacting compatibilizers are studied. Dynamic mechanical analysis showed an enhanced elastic modulus and reduced damping upon nanoclay fillers incorporation, also α-relaxation peak was shifted up while β-relaxation was not affected. Thermogravimetry exhibited a synergistic effect in thermal stability of the blend accompanied by a reduction in decomposition rate. This effect was more pronounced in presence of compatibilizers. The addition of nanoclay fillers generally led to an enhancement of thermal resistance; however, a dual function was evident, namely preventive and catalytic, respectively prior to and after onset of degradation.View full textDownload full textKeywordsBlend nanocomposite, Poly(trimethylene terephthalate), Polypropylene, Thermal propertiesRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/03602559.2012.661903
