Abstract
Poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV) and poly(ethylene succinate) (PES) are both biodegradable semicrystalline polyesters. Phase behavior, crystal structure, crystallization kinetics, and mechanical properties of fully biodegradable PHBV/PES blends were investigated by differential scanning calorimetry (DSC), polarizing optical microscopy (POM), wide angle X-ray diffraction ...

17. "Miscible Crystalline/Crystalline Polymer Blends of Poly(vinylidene fluoride) and Poly(butylene succinate-co-butylene adipate): Spherulitic Morphologies and Crystallization Kinetics" Qiu Z, Yan C, Lu J, Yang W. Macromolecules 2007; 40 (14): 5047 -5053.
Spherulitic morphologies and overall crystallization kinetics of miscible poly(vinylidene fluoride) (PVDF)/poly(butylene succinate-co-butylene adipate) (PBSA) blends were studied by polarizing optical microscopy (POM), differential scanning calorimetry (DSC), and wide-angle X-ray diffraction (WAXD). PVDF and PBSA crystallize separately in the blends. For the high-Tm component PVDF, the crystalliza...

16. "Various crystalline morphology of poly(butylene succinate-co-butylene adipate) in its miscible blends with poly(vinylidene fluoride)". Qiu Z, Yan C, Lu J, Yang W, Ikehara T, Nishi T. Journal of Physical Chemistry B Volume 111, Issue 11, 22 March 2007, Pages 2783-2789.
Abstract
Poly(vinylidene fluoride) (PVDF) and poly (butylene succinate-co-butylene adipate) (PBSA) are crystalline/crystalline polymer blends with PVDF being the high-Tm component and PBSA being the low-Tm component, respectively. PVDF/PBSA blends are miscible as shown by the decrease of crystallization peak temperature and melting point temperature of each component with increasing the other c...

13. "Penetrating spherulitic growth in poly(butylene adipate-co-butylene succinate)/poly(ethylene oxide) blends" Ikehara T, Kimura H, Qiu, Z. Macromolecules Volume 38, Issue 12, 14 June 2005, Pages 5104-5108
The spherulitic growth of poly(ethylene oxide) (PEO) was found to continue in the spherulites of poly(butylene adipate-co-butylene succinate) (PBAS) in the simultaneous spherulitic growth process of the two components in PBAS/PEO blends. This phenomenon, namely the formation of interpenetrating spherulites (IPS), was analyzed on the basis of birefringence observed by polarizing optical microscopy....

38. The crystal structure and drawing-induced polymorphism in poly(aryl ether ketone)s. 2.Poly(ether ether ketone ketone),PEEKK. Wang SG, Wang JZ, Liu TX,et al. MACROMOL.CHEM.PHYS.198(4):969-982,1997.
The crystal structure, morphology and polymorphism induced by uniaxial drawing of poly(ether ether ketone ketone) [PEEKK] have been studied by transmission electron microscopy (TEM), electron diffraction (ED) and wide angle X-ray diffraction (WAXD). On the basis of WAXD and ED patterns,the crystal structure of unoriented PEEKK is determined to have two-chain orthorhombic packing with unit cell par...

Fluorescent linear CO2-derived poly(hydroxyurethane) for cool white LED
关键字：poly(hydroxyurethane)，cool white LED，
The fluorescent properties of a linear poly(hydroxyurethane) (P1) from carbon dioxide, siloxane (Si–O–Si)-containing bisepoxide and diamine are described. P1 showed strong photoluminescence with a quantum yield of up to 23.6%, high photostability, and broad absorption and emission spectra either in bulk or solution. The flexibility and hydrophobicity of the Si–O–Si linkage in P1 were utilize...

02 Catalyzing carbonization of poly(L-lactide) by nanosized carbon black combined with Ni2O3 for improving flame retardancy
关键字：poly(L-lactide)
Catalyzing the carbonization of a polymer itself to form a protective carbonaceous layer has attracted tremendous interest in the flame retardancy of polymers, but the efficiency of this strategy was largely limited to polymers containing heteroatoms within their backbone. In this study, a novel type of combined catalyst, consisting of nanosized carbon black (CB) and Ni2O3, was found to efficientl...

47 Polyvinyl alcohol/GO-MMT nanocomposites: Preparation, structure and properties
关键字：Clay Graphene oxide Nanocomposites Poly(vinyl alcohol)
A facile, efficient and environment friendly method is established to prepare poly(vinyl alcohol) (PVA) based graphene oxide-montmorillonite (GO-MMT) nanocomposites in aqueous media. GO-MMT nanohybrid is obtained by the combination of GO and MMT in water without any reducing or stabilizing agents. The formation of GO-MMT nanohybrid is due to the hydrogen bonding and crosslinking effects. The sodiu...

Conformational Identification and Phase Transition Behavior of Poly(trimethylene 2,6-naphthalate) α?Form Modification
关键字：PTN, α?Form crystal, conformation, Phase transtion
Poly(trimethylene 2,6-naphthalate) (PTN) is one of the 1,3-propanediol (PDO)-based aromatic polyesters which has potential applications for special barrier films and
packaging due to its excellent oxygen and carbon dioxide gas barrier property. In this work, we investigated the chain conformation and phase transition behavior of poly-
(trimethylene 2,6-naphthalene) (PTN) α-form crystal with synch...

Improving dielectric properties of poly(vinylidene fluoride) composites: effects of surface functionalization of exfoliated graphene
关键字：PVDF composites
To investigate the effects of surface functionalization of exfoliated graphene (EG) on the crystalline form of ?-phase and dielectric properties of poly(vinylidene fluoride) (PVDF), we prepared PVDF-based composites reinforced by different functionalized EG. The X-ray photoelectron spectroscopy results indicated that a wide variety of chemical functional groups such as C?OH, C?O?C, C=O, COOH...
