6. "Crystallization Behaviour of Biodegradable Poly(ethylene succinate) from the Amorphous State". Qiu ZB,* Ikehara T, Nishi T.* Polymer 2003; 44: 5429-5437.
Nonisothermal and isothermal crystallization kinetics of biodegradable poly(ethylene succinate) (PES) from the amorphous state were studied by differential scanning calorimetry (DSC). For the nonisothermal crystallization, there were two crystallization exotherms upon heating from the amorphous state. One major crystallization exotherm located at low temperature corresponded to the real cold...

5. "Miscibility and Crystallization of Poly(ethylene oxide) and Poly(ε-caprolactone) Blends". Qiu ZB,* Ikehara T, Nishi T. Polymer 2003; 44: 3101-3106.
Blends of poly(ethylene oxide) (PEO) with poly(ε-caprolactone) (PCL), both semicrystalline polymers, were prepared by co-dissolving the two polyesters in chloroform and casting the mixture. Phase contrast microscopy was used to probe the miscibility of PEOB/PCL blends. Experimental results indicated that PEO was immiscible with PCL because the melt was biphasic. Crystallization of PEO/PCL ...

4. "Melting Behaviour of Poly(butylene succinate) in Miscible Blends with Poly(ethylene oxide)". Qiu ZB,* Ikehara T, Nishi T. Polymer 2003; 44: 3095-3099.
The melting behaviour of poly(butylene succinate) (PBSU) in miscible blends with poly(ethylene oxide) (PEO), which is a newly found polymer blends of two crystalline polymers by our group, has been investigated by conventional differential scanning calorimetry (DSC). It was found that PBSU showed double melting behaviour after isothermal crystallization from the melt under certain crystallization ...

3. "Miscibility and Crystallization in Crystalline/Crystalline Blends of Poly(butylene succinate)/Poly(ethylene oxide) ". Qiu ZB,* Ikehara T, Nishi T. Polymer 2003; 44: 2799-2806.
Miscibility and crystallization behavior have been investigated in blends of poly(butylene succinate) (PBSU) and poly(ethylene oxide) (PEO), both semicrystalline polymers, by differential scanning calorimetry and optical microscopy. Experimental results indicate that PBSU is miscible with PEO as shown by the existence of single composition dependent glass transition temperature over the entire com...

2. "Poly(hydroxybutyrate)/Poly(butylene succinate) Blends: Miscibility and Nonisothermal Crystallization" Qiu ZB,* Ikehara T, Nishi T. Polymer 2003; 44: 2503-2508
Four blends of poly(hydroxybutyrate) (PHB) and poly(butylene succinate) (PBSU), both biodegradable semicrystalline polyesters, were prepared with the ratio of PHB/PBSU ranging from 80/20 to 20/80 by co-dissolving the two polyesters in chloroform and casting the mixture. Differential scanning calorimetry (DSC) and optical microscopy (OM) were used to probe the miscibility of PHB/PBSU blends. Experi...

57. Growth of Carbon Nanotubes on Clay: Unique Nanostructured Filler for High-Performance Polymer Nanocomposites. W.D. Zhang*, I.Y. Phang, T.X. Liu*. Adv. Mater. 18(1), 73-77, 2006.
Carbon nanotubes (CNTs) have been grown on the Fe-modified montmorillonite (clay) by chemical vapor deposition and the as-prepared CNTs-clay hybrid, without any further purification, was directly incorporated into nylon-6 (PA6) by melt-blending. The intercalation of the clay by Fe2O3 was further delaminated to well-separated nanoclay platelets by the growth of CNTs on them, thus forming a th...

The nanoindentation behavior and morphology of the injection-molded specimens of nylon-6 (PA6)/clay nanocomposites prepared by melt-compounding have been studied in present study. The elastic and plastic properties as well as creep behavior of PA6 and its nanocomposites are comparatively evaluated as the function of clay loading by using nanoindentation technique. The anisotropic characteristics i...

The influence of annealing on the morphologies and optical properties of phenyleneethynylene pentamer films has been investigated byusing optical microscopy, UV–vis spectroscopy, steady-state and time-resolved photoluminescence (PL). The optical microscopy study showsthat the grainy morphology of crystallites with irregular shapes and sizes of the spincoated oligomer films reorganize into well-or...

26. Multiple melting behavior in isothermally cold-crystallized isotactic polystyrene. Liu T*, Petermann J. POLYMER 42 (15): 6453-6461 JUL 2001.
The multiple melting behavior and lamellar morphologies of isotactic polystyrene (iPS) isothermally crystallized from the glassy state have been investigated by differential scanning calorimetry (DSC) and transmission electron microscopy (TEM). The influences of different experimental variables (such as crystallization temperature and time, heating rate) on the melting behavior of iPS are studied....

13. Moisture sorption and permeation in polyamide 6/clay nanocomposite films. Low HY, Liu TX, Loh WW. POLYMER INTERNATIONAL 53 (12): 1973-1978 DEC 2004.
The moisture transport properties of a polyamide 6/clay nanocomposite have been studied through moisture sorption and permeation rate measurements. The temperature and concentration dependence of the steady state moisture uptake and permeation rate from the two types of experiment are distinctly different. The activation energy of moisture permeation obtained from the sorption experiment is lower ...
