The MesoDyn method is used to investigate associative structures in aqueous solution of a nonionic triblock copolymer consisting of poly(propylene oxide) capped on both ends with poly(ethylene oxide) chains. The effect of adsorbing (hydrophobic) and nonadsorbing (hydrophilic) solid surfaces in contact with aqueous solutions of the polymer is elucidated. The macromolecules form self-assembled st...

Cereal Chem. 72(6):559-563 Films were prepared by casting and drying alkaline aqueous filmelongation at break (E). TS values ranged from 1.4 to 3.9 MPa and E forming solutions of soy protein isolate (SPI). Four additional types of values ranged from 83 to 152%. Water vapor permeability of the films films were made by combining SPI with poly(ethy1ene oxide) (PEO) in ranged from 3.0 x to 4.0 x gl...

Molecular dynamics (MD) simulations of crystalline poly(ethylene oxide) (PEO) have been carried out in order to study its vibrational properties. The vibrational density of states has been calculated using a normal mode analysis (NMA) and also through the velocity autocorrelation function of the atoms. Results agree well with experimental spectroscopic data. System size effects in the crystalli...

Various (AB)n and (ABAC)n segmented copolymers with hydrophilic hydrophobic segments are processed via melt electrowriting (MEW). Two different composed of bisurea poly(dimethyl siloxane) (PDMS) or poly(propylene oxide)-poly(ethylene oxide)-poly(propylene oxide) (PPO-PEG-PPO) segments, while the amphiphilic consist in combination PDMS PPO-PEG-PPO ratios, explored. All copolymer compositions usi...
