Liquid Crystalline Transition and Gel-Sol Transitions for concentrated Microcrystalline Cellulose (MCC)/1-Ethyl-3-Methylimidazolium Acetate (EMIMAc) Solutions
Liquid crystalline (LC) phase transition and gel?sol transition in the solutions of microcrystalline cellulose (MCC) and ionic liquid (1-ethyl-3-methylimidazolium acetate, EMIMAc) have been investigated through a combination of polarized optical microscope (POM) observation and rheological measurements. Molecular LC phase forms at the 10 wt % cellulose concentration, as observed by POM, whereas th...

Liquid Crystalline Phase Behavior and Sol–Gel Transition in Aqueous Halloysite Nanotube Dispersions
The liquid crystalline phase behavior and sol?gel transition in halloysite nanotubes (HNTs) aqueous dispersions
have been investigated by applying polarized optical microscopy (POM), macroscopic observation, rheometer, small-angle X-ray
scattering, scanning electron microscopy, and transmission electron microscopy. The liquid crystalline phase starts to form at the
HNT concentration of 1 wt %, and...

Prediction of glass transition temperatures for polystyrenes from cyclic dimer structures using artificial neural networks
The quantitative structure-property relationship (QSPR) was studied for the prediction of glass transition temperatures of polystyrenes on a set of 107 polystyrenes using artificial neural networks combined with genetic function approximation. Descriptors of the polymers were derived from their corresponding cyclic dimer structures. A nonlinear model with four descriptors was developed with square...

Morphological transition of dry vesicles into onion-like multilamellar micelles induced through heating at high temperature
In this Letter, we report the morphological transition of dry block copolymer vesicles into onion-like multilamellar micelles induced through heating. When the temperature is higher than the glass transition temperature of block copolymer, the vesicles can collapse, and finally form onion-like multilamellar micelles via micro phase separation. This phenomenon is observed in both A–B and A–B–A...

Droplet-cluster transition in sheared polyamide 6–poly(styrene-ethylene-butadiene-styrene)–polypropylene ternary blends
We have used a Linkam CSS 450 stage equipped with an optical microscope to study online the evolution of the morphology and structure of polyamide 6 (PA6)–poly(styrene-ethylene-butadiene-styrene) (SEBS)–polypropylene (PP) ternary blends under shear flow. At a high shear rate (60?s?1), large drops of PA6 and SEBS broke up to form small randomly distributed PA6 droplets covered by SEBS in the...

UNIQUE EVOLUTION OF SPATIAL AND DYNAMIC HETEROGENEITY ON THE GLASS TRANSITION BEHAVIOR OF PVPh/PEO BLENDS
Glass transition behavior of hydrogen bonded polymer blends of poly(vinyl phenol) (PVPh) and poly(ethylene oxide) (PEO) is systematically investigated using normal differential scanning calorimetry (DSC) and recently developed multifrequency temperature-modulated DSC (TOPEM), in combination with Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) techniques, focusin...

Coil-to-rod conformational transition and single chain structure of graft copolymer by tuning the graft density
The chain conformation and individual chain structures of the graft copolymers ethyl cellulose grafting poly (acrylic acid) (EC-g-PAA) were investigated by laser light scattering (LLS) and atom force microscopy (AFM). The EC-g-PAA graft copolymers with two different side chain lengths and side chain grafting densities were synthesized via atom transfer radical polymerization (ATRP) from ethyl c...
