Rheology of multi-walled carbon nanotube/poly(butylene terephthalate) composites
Multi-walled carbon nanotube/Poly(butylene terephthalate) nanocomposites (PCTs) were prepared by melt compounding. The microstructure of PCTs was investigated using transmission electron micrographs and Fourier transform infra-red spectrometer. The linear and nonlinear as well as transient rheological properties of PCTs were characterized by the parallel plate rheometer. The results reveal that th...

Poly(phenylene sulfide) magnetic composites. II. Crystallization, thermal, and viscoelastic properties
Poly(phenylene sulfide)/ferrosoferric oxide composites
(PPS/Fe3O4) with various loading levels were prepared
by melt compounding. The crystallization, thermal, and
viscoelastic properties were characterized respectively
by the DSC, DMA, TGA and parallel plate rheometer.
The results reveal that the well-dispersed Fe3O4 particle
restricts the segmental motion of polymer chain,
leading to a remarkabl...

Phase behavior and its viscoelastic response of polylactide/poly(epsilon-caprolactone) blend
Polylactide (PLA)/polycaprolactone (PCL) blends with various blend ratios were prepared via melt mixing. The morphology, linear and non-linear viscoelastic properties of the blend were studied using scanning electron microscope (SEM) and cone-plate rheometer. Three typical immiscible morphologies, i.e., spherical droplet, fibrous and co-continuous structure can be observed at various compositions....

Crystallization and thermal behavior of multiwalled carbon nanotube/poly(butylenes terephthalate) composites
Multiwalled carbon nanotube/poly(butylene terephthalate) composites (PCTs) were prepared by melt mixing. The nonisothermal crystallization and thermal behavior of PCTs were respectively investigated by X-ray diffractometer, polarized optical microscope, differential scanning calorimeter, dynamic mechanical thermal analyzer, and thermogravimetric analyzer. The presence of nanotubes has two disparat...

Selective Localization of Multiwalled Carbon Nanotubes in Poly(epsilon-caprolactone)/Polylactide Blend
Poly(epsilon-caprolactone)/polylactide blend (PCL/PLA) is an interesting biomaterial because PCL and PLA present good complementarity in their physical properties and biodegradability. However, the thermodynamic incompatibility between two component polymers restricts further applications of their blend. In this work, we used functionalized multiwalled carbon nanotube (MWCNT) to control the m...

Effect of Steady Shear on the Morphology of Biodegradable Poly(epsilon-Caprolactone)/Polylactide Blend
The biodegradable polymer blend containing 70/30 weight ratio of poly(ε-caprolactone) (PCL) and polylactide (PLA) was prepared by means of melt mixing. The evolution of the “sea-island” phase structure in the steady shear flow was studied using scanning electron microscope (SEM) and parallel-plate rheometer. The results show that the morphological evolution induced by steady shear follows diffe...

Viscoelastic Interfacial Properties of Compatibilized Poly(epsilon-caprolactone)/Polylactide Blend
Poly(ε-caprolactone)/polylactide blend (PCL/PLA) is an interesting biomaterial because the two component polymers show good complementarity in their physical properties. However, PCL and PLA are incompatible thermodynamically and hence the interfacial properties act as the important roles controlling the final properties of their blends. Thus, in this work, the PCL/PLA blends were prepared by mel...

Effect of epoxy resin on the thermal behaviors and viscoelastic properties of poly(phenylene sulfide)
In this work, thermal behaviors and viscoelasticity of the PPS/epoxy resin mixtures prepared by melt mixing were studied, and the rheology was used as a tool to further explore the relation between chain structures and properties of the mixtures. The results show that the epoxy resin can promotes degradation and branching of the PPS during melt mixing due to its poor thermal stability. The formati...

Banded spherulites of electrospun poly(trimethylene terephthalate)/carbon nanotube composite mats
The crystallization of poly(trimethylene terephthalate) (PTT) composites containing carbon nanotubes (CNTs) were studied in this work. The electrospinning technology was employed successfully to fabricate thin film samples with well-embedded CNTs for spherulite observations using atom force microscopy. The results show that the composites present a higher overall crystallization rate than that of ...

Percolation Behavior and Isothermal Crystallization of Poly(butyene Succinte)/Carbon Nanotube Composites
Carbon nanotube (CNT) filled poly(butylene succinate) composites (PBSCNs) were prepared by melt compounding. The oscillatory rheological properties and crystallization behavior and kinetics were then investigated. The results show that the percolation network of CNTs in the small amplitude oscillatory shear flow is temperature dependent and the values of percolation thresholds reduce gradually wit...
