Effect of the degree of branching on atomic-scale free volume in hyperbranched poly[3-ethyl-3-(hydroxymethyl)oxetane], A positron study
Positron annihilation lifetime (PAL) measurements have been used to study the effect of degree of branching (DB) and temperature on the atomic-scale free-volume properties and the structural transitions for hyperbranched polymer PEHO. According to the finite-term positron lifetime analysis and differential scanning calorimeter (DSC) measurements, the glass transition temperature was determined, wh...

Silica-g-Poly[2-(N,N-dimethyl amino) ethyl methacrylate] Hybrid Nanospheres as Stabilizer for Metallic Nanocolloids
The silica-g-poly[2-(N,N-dimethyl amino)ethyl methacrylate] (SiO2-g-PDMAEMA) hybrid microspheres with
polymer brushes were synthesized by the surface-grafted atom transfer radical
polymerization (ATRP) from the surface alkyl bromide functionalized silica nanospheres.
The inorganic nanosphere as surface-initiating polymerization site was prepared
by the amide reaction of 2-bromoisobutyryl brom...

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...

Hierarchical mesoporous silica prepared from ethyl-cyanoethyl cellulose cholesteric liquid crystalline phase
Porous silica with hierarchical structures was prepared from ethyl-cyanoethyl cellulose/poly(3-(methacryloyloxy)propyl-trimethoxysilane) (E-CE)C/P(MPTOS) composites with fixed cholesteric liquid crystalline (LC) phase. The scanning and transmission electron microscopy (SEM and TEM) and N-2 sorption measurements results indicate that the silica prepared from cholesteric LC composites is of hie...

Synthesis, self-assembly and drug release behaviors of pH-responsive copolymers ethyl cellulose-graft-PDEAEMA through ATRP
The pH-responsive ethyl cellulose graft poly(2-(diethylamino) ethyl methacrylate) (EC-g-PDEAEMA) copolymers were synthesized through atom transfer radical polymerization (ATRP). Kinetic analysis confirmed the reaction is living and controllable. The graft copolymers can form micelles in acid aqueous medium. The critical micelle concentration (CMC) of the graft copolymers decreases with the in...

A novel, amphiphilic ethyl cellulose grafting copolymer with poly(2-hydroxyethyl methacrylate) side chains and its micellization
Ethyl cellulose-graft-poly(2-hydroxyethyl methacrylate) (EC-graft-PHEMA) graft copolymers were synthesized by atom-transfer radical polymerization (ATRP) in methanol. The graft copolymers were characterized by means of gel-permeation chromatography (GPC) and H-1 NMR spectroscopy. The kinetic study indicated that the polymerization was controllable. The EC-graft-PHEMA copolymers self-assembled...
