18. Melting behavior of isotactic polystyrene revealed by differential scanning calorimetry and transmission electron microscopy. Liu TX*. EUROPEAN POLYMER JOURNAL 39 (7): 1311-1317 JUL 2003.
The triple melting behavior and lamellar morphologies of isotactic polystyrene isothermally crystallized from the glassy state have been investigated by differential scanning calorimetry (DSC), temperature-modulated DSC and transmission electron microscopy (TEM). The combination of thermal analysis measurements and morphological observations indicates that: (1) The lowest endothermic peak, the so-...

15. Crystallization and melting behavior of polyester/clay nanocomposites. Phang IY, Pramoda KP, Liu TX*, He CB. POLYMER INTERNATIONAL 53 (9): 1282-1289 SEP 2004.
Polyester/clay nanocomposites were prepared by melt compounding with different clay loadings. Comparing against neat polyester resins, the crystallization and multiple melting behavior of the nanocomposites was investigated by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). Nanoclay filler is an effective heterogeneous nucleating agent, as evidenced by a decrease and an increa...

12. Crystal transformation and thermomechanical properties of poly(vinylidene fluoride)/clay nanocomposites. Pramoda KP, Mohamed A, Phang IY, Liu TX*. POLYMER INTERNATIONAL 54 (1): 226-232 JAN 2005.
The crystal transformation and thermomechanical properties of melt-intercalated poly(vinylidene fluoride) (PVDF)/clay nanocomposites are reported in this study. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were used to study the thermal properties of PVDF and its nanocomposites with various clay concentrations. The incorporation of clay in PVDF results in the format...

9. Fracture and toughening behavior of Aramid fiber/epoxy composites.Wang L, Tjiu WC, Teh SF, He CB, Liu TX*. POLYMER COMPOSITES 26 (3): 333-342 JUN 2005.
The effect of short Aramid fibers on the fracture and toughening behavior of epoxy with high glass transition temperature has been studied. Fine dispersion of the fibers throughout the matrix is evidenced by optical microscopy. Compared with neat epoxy resin, the fracture toughness (K-IC) of the composites steadily increases with increasing fiber loading, indicating that addition of Aramid fibers ...

4. Nanoindentation and morphological studies on nylon 66/organoclay nanocomposites. II. Effect of strain rate. Shen L, Phang IY, Liu TX*, Zeng KY. POLYMER 45 (24): 8221-8229 NOV 11 2004.
Strain rate effects on surface deformation behavior of exfoliated nylon 66 (PA66)/organoclay nanocomposites have been explored by nanoindentation in present study. Sharp indenter (Berkovich) has been used to indent on the surfaces of polymer/clay nanocomposite with different strain rates. Significant strain-rate hardening has been found consistently existing in both neat PA66 and its nanocomposite...

3. Nanoindentation and morphological studies on nylon 66 nanocomposites. I. Effect of clay loading. Shen L, Phang IY, Chen L, Liu TX*, Zeng KY. POLYMER 45 (10): 3341-3349 MAY 11 2004.
Nanoindentation technique has been used to investigate the mechanical properties of exfoliated nylon 66 (PA66)/clay nanocomposites in present study. The hardness, elastic modulus and creep behavior of the nanocomposites have been evaluated as a function of clay concentration. It indicates that incorporation of clay nanofiller enhances the hardness and elastic modulus of the matrix. The elastic mod...

17 Catalytic conversion of linear low density polyethylene into carbon nanomaterials under the combined catalysis of Ni2O3 and poly(vinyl chloride)
关键字:Adsorption, Carbon nanomaterial, Catalysis, Methylene blue, Polymer A one-pot method was used to prepare magnetic Ni/carbon (Ni/C) nanomaterials by catalytic carbonization of linear low density polyethylene (LLDPE) under the combined catalysis of Ni2O3 and polyvinyl chloride (PVC) resin. The yield of Ni/C nanomaterials was determined by the pyrolysis temperature, the type and the content of PVC resin. The yield of magnetic Ni/C nanomaterials first increased and th...

Reinforcement of shape-memory poly(ethylene-co-vinyl acetate) by carbon fibre to access robust recovery capability under resistant Condition`
关键字:Smart materials, Carbon fibresPolymer-matrix composites, Shape memory polymer Poly (ethylene-co-vinyl acetate) (EVA), as one of commercial polymers, has been used early to fabricateshape-memory polymers (SMPs). However, its low recovery stress restricts the potential applications insome tough conditions due to its high ?exible feature. Herein, we developed a series of EVA-basedcomposites (cEVA/CF) with remarkably enhanced recovery stress both in free-state and resistant con...

Dual Drug Backboned Shattering Polymeric Theranostic Nanomedicine for Synergistic Eradication of Patient-Derived Lung Cancer
关键字:Dual sensitivity, shattering polymer, precise nanomedicine, patient-derived tumor, computer tomography
Most of current nanoparticle-based therapeutics
worldwide failing in clinical trials can be mostly attributed to three major
challenges: i) lack of optimum drug
delivery platform with precise composition, ii)
lack of way of directly monitoring the fate of a specific drug rather than
using any other labelling molecules for a compromise and iii) lack of reliable cancer models with high fidelity ...

A nitrogen-rich, azaindole-based microporous organic network: synergistic effect of local dipole–π and dipole–quadrupole interactions on carbon dioxide uptake
关键字:microporous organic polymer, dipole–π and dipole–quadrupole interactions
A new type of microporous organic polymer with azaindole units (N-PEINK) has been designed. The resulting N-PEINK exhibits good chemical and thermal stability with a decomposition temperature of 550 °C. Taking advantage of the synergistic effect of local dipole–π and dipole–quadrupole interactions between azaindole and carbon dioxide (CO2), the CO2 uptake capacity of the polymer reaches 20.8...
