Fabrication and properties of poly(tetrafluoroethylene-co-hexafluoropropylene) hollow fiber membranes
Poly(tetrafluoroethylene-co-hexafluoropropylene) (FEP) hollow fiber membranes have been fabricated
for the first time via the melt spinning method. Dioctyl phthalate (DOP) as the diluent and a composite
powder (composed of soluble and insoluble particles) as the pore-creating agent were used in this study.
The addition of the composite powder brought about a dissolved pore structure and interfacia...

Preparation and characterization of poly(tetrafluoroethylene–cohexafluoropropylene) (FEP) hollow fiber membranes for desalination
High porosity and strong hydrophobicity of polymeric hollow fiber membranes are of great
interest for membrane distillation (MD). Poly(tetrafluoroethylene–cohexafluoropropylene)
(FEP) exhibits excellent chemical resistance, thermal stability, strong hydrophobicity owing
to the perfluoro-structure. Comparing with polytetrafluoroethylene (PTFE), the meltable
property endows FEP good processability ...

Insights into the Nucleation Role of Cellulose Crystals during Crystallization of Poly(Beta-hydroxybutyrate)
Carbohydrate
Polymers,
2015, 134C, 508-515
ABSTRACT:
Cellulose crystals, including microcrystalline cellulose
(MCC) and nanocrystalline cellulose (NCC), were used as the fillers to prepare green
composites with poly(beta-hydroxybutyrate) (PHB) by melt mixing for
crystallization study. The results reveal that the spherulite morphology of PHB and its composites depends
highly on the ...

Effect of diisocyanates as compatibilizer on the properties of ramie/poly(lactic acid) (PLA) composites
Ramie/PLA composites with the diisocyanates as compatibilizer were
fabricated by extrusion and injection molding. The influence of
different diisocyanates and various diisocyanate content on the
mechanical properties and thermal properties of the composites was
investigated. The presence of the diisocyanates in the composites lead
to the improvements in mechanical properties and thermal prope...

Effects of Fullerene Solubility on the Crystallization of Poly(3-hexylthiophene) and Performance of Photovoltaic Devices
The substantial crystallization suppression of poly(3-hexylthiophene) (P3HT) in the
untreated P3HT:C60 composite film prepared from o-dichlorobenzene (ODCB) solution
has been revealed. Besides, the effective conjugation length of P3HT in this composite
has been nearly maintained to that in the solution. The different crystallization behaviors of P3HT in its composites with C60 and [6,6]-pheny...

Highly Stable Polyaniline-Poly(sodium 4-styrenesulfonate) Colloid for Sensing of Amines
Sensing technology is the key of intelligent packaging. A variety of different sensing systems for indicating freshness through intelligent packaging have been presented. Polyaniline (PANI) can change its color reversibly through the acid-base reaction with reactive compounds and has been widely used in different kinds of sensors. However, because PANI is insoluble in common organic...

Polyaniline:poly(sodium 4-styrenesulfonate)-stabilized gold nanoparticles as efficient, versatile catalysts
Gold nanoparticles were stabilized by a polyaniline:poly(sodium 4-styrenesulfonate) (PANI:PSS) matrix and readily dispersed in water over a wide range of pH. In contrast to nanoparticles passivated by alkanethiolates that formed a compact capping layer on the nanoparticle surface, the PANI:PSS–Au nanocomposites exhibited apparent catalytic activity in the reduction of 4-nitrophenol...

Langmuir 2015: Effects of Water on the Single-chain Elasticity of poly(U) RNA
Water,
the dominant component in the physiological condition, is a complicated
solvent, which greatly affects the properties of solute molecules. Here, we utilize
atomic force microscope-based single-molecule force spectroscopy to study the
influence of water on the single-molecule elasticity of an unstructured
single-stranded RNA (poly(U)). In nonpolar solvents, RNA presents its inherent
elastici...

009. Multiscale simulations of the structure and dynamics of stereoregular poly(methyl methacrylate)s
The chain tacticity of a polymer is a key influence on its structure and dynamics, which ultimately determine its properties. While they have great potential to elucidate the influence of chain tacticity, all-atom molecular simulations are often restricted to short chains and small systems. In thiswork, two typical stereoregular poly(methyl methacrylate) melts were ...
