30. Crystal structure and drawing-induced polymorphism in poly(aryl ether ether ketone). IV. Liu TX, Wang SE, Mo ZS, Zhang HF. JOURNAL OF APPLIED POLYMER SCIENCE 73 (2): 237-243 JUL 11 1999.
A new crystal modification induced by strain and denoted as form II exists alongside the dominant form I structure in the uniaxially oriented poly(ether ether ketone) (PEEK) and the related polymers. The crystal structure of form II for PEEK is also found to possess a two-chain orthorhombic packing with unit cell parameters of a equal to 0.475 nm, b equal to 1.060 nm, and c equal to 1.086 nm.

25. Micro- and nanomorphologies of isotactic polystyrene revealed by PLM, AFM, and TEM. Liu TX*, Ma KX, Liu ZH, He CB, Chung TS. JOURNAL OF APPLIED POLYMER SCIENCE 86 (2): 422-427 OCT 10 2002.
The spherulitic and lamellar morphologies of isotactic polystyrene (iPS) isothermally crystallized from the glassy state were investigated by polarized light microscopy (PLM), atomic force microscopy (AFM), and transmission electron microscopy (TEM). The AFM phase images and TEM bright-field electron micrographs revealed that the iPS spherulites consist of a number of dominant edge-on lamellae whi...

14. Morphology and fracture behavior of intercalated epoxy/clay nanocomposites. Liu TX*, Tjiu WC, Tong YJ, He CB, Goh SS, Chung TS. JOURNAL OF APPLIED POLYMER SCIENCE 94 (3): 1236-1244 NOV 5 2004.
Epoxy/clay nanocomposites were prepared by swelling organoclay in an epoxy resin, diglycidyl ether of bisphenol A, followed by curing with an aromatic hardener, diethyltoluenediamine. A combination of X-ray diffraction with transmission electron microscopy showed the coexistence of intercalated and exfoliated clay morphologies throughout the matrix. In addition, a microscopic and homogeneous dispe...

10. Fracture behaviour of poly(ethylene terephthalate) fiber toughened epoxy composites. Teh SF, Liu TX*, Wang L, He CB. COMPOSITES PART A-APPLIED SCIENCE AND MANUFACTURING 36 (8): 1167-1173 2005.
Thermoplastic poly(ethylene terephthalate) (PET) fibers have been used to toughen an intrinsically brittle epoxy resin with high glass transition temperature. The morphologies and chemical properties of the as-received and the surface-modified PET fibers are comparatively investigated by scanning electron microscopy (SEM) and time-of-flight static secondary ion mass spectrometry (ToF-SIMS). Strong...

High molecular weight polyesters derived from bio-based 1,5-pentanediol and a variety of aliphatic diacids: Synthesis, characterization and thermo-mechanical properties
关键字：Biobased polymers, Biodegradable polymers, Poly(1,5-pentylene dicarboxylate)s, Thermal property, Mechanical property
High molecular weight aliphatic polyesters were synthesized from biobased 1,5-pentanediol and aliphatic diacids with 4, 5, 6, 9, 10, or 12 carbon atoms via melt polycondensation. The poly(1,5-pentylene dicarboxylate)s were characterized with intrinsic viscosity, gel permeation chromatography (GPC), nuclear magnetic resonance (NMR), differential scanning calorime...
