Alumina/water suspensions in the presence of PEO–PPO–PEO triblock copolymers [PDF]

Journal of the European Ceramic Society, 2004
Abstract The aim of this study was to investigate the stability and dispersion behaviour of aqueous alumina suspensions in the presence of polyethylene oxide–polypropylene oxide–polyethylene oxide (PEO–PPO–PEO) type triblock copolymers. For this purpose alumina suspensions at various solids loadings were prepared using four different methods.

Evolution of PEO coatings on AM50 magnesium alloy using phosphate-based electrolyte with and without glycerol and its electrochemical characterization

Journal of Magnesium and Alloys, 2020
PEO coatings were synthesized from phosphate-based (bP-PEO) and glycerol added phosphate-based (gP-PEO) electrolytes with different processing times. For both bP-PEO and gP-PEO coatings treated with different processing time its morphology, elemental and

THE MICELLIZATION OF PLURONICS (PEO-PPO-PEO TRIBLOCK COPOLYMERS)

Science and Technology Development Journal, 2009
The micellization of several Pluronics (PEO-PPO-PEO triblock copolymers) was investigated by Differential Scanning Calorimetry (DSC). These copolymers were also characterized and purified by liquid chromatography. The PEO/PPO compositions of Pluronics were determined by 'H-NMR.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...
