Native cellulose is insoluble in water, despite the high number of hydrogen bonding sites per chain, as molecules preferably hydrogen bond to each other, preventing its use in industrial applications. The modification of cellulose has received consid

Flow-Induced Formation of Thin PEO Fibers in Water and Their Stability After the Strain Release

Autor: Jens-Uwe Sommer, Sergii Donets, Olga Guskova

Publikováno v: The Journal of Physical Chemistry B

Recently, we have shown that a tensile stress applied to chains of poly(ethylene oxide) (PEO) in water reduces the solubility and leads to phase separation of PEO chains from water with the formation of a two-phase region. In this work, we further el

Molecular Dynamics Simulations of Strain-Induced Phase Transition of Poly(ethylene oxide) in Water

Autor: Sergii Donets, Jens-Uwe Sommer

Publikováno v: The Journal of Physical Chemistry B

We study the dilute aqueous solutions of poly(ethylene oxide) (PEO) oligomers that are subject to an elongating force dipole acting on both chain ends using atomistic molecular dynamics. By increasing the force, liquid-liquid demixing can be observed

Tapered block copolymers offer an exciting opportunity to tailor the interfacial region between different components by conserving their phase-separated mesoscale structure, which enable the generation of polymer systems with the desired spatio-dynam

Both the device composition and fabrication process are well-known to crucially affect the power conversion efficiency of polymer solar cells. Major advances have recently been achieved through the development of novel device materials and inkjet pri
