Ion-Conductive Nanostructured Polymer Films Formed by Photopolymerization of Lyotropic Columnar Liquid-Crystalline Monomers, Composed of a Zwitterionic Compound and a Protic Ionic Liquid

open access: yesCrystals, 2020
Here, we report on a new family of columnar nanostructured polymer films forming protic nanochannels that exhibit good ionic conductivities in the order of 10−4–10−3 S cm−1 at ambient temperature.

Network formation of low molecular weight ‘liquid’ polymers studied by gel permeation chromatography and stress-strain analysis according to Mooney-Rivlin

open access: yesPolymer Testing, 2023
The rheological and mechanical properties of elastomers are defined by their different networks: The crosslink network and the filler network. The crosslink network is influenced by the polymer structure.

Polymers at Liquid/Vapor Interface [PDF]

open access: yesACS Macro Letters, 2017
Polymers confined to the liquid/vapor interface are studied using molecular dynamics simulations. We show that for polymers which are weakly immiscible with the solvent, the density profile perpendicular to the liquid/vapor interface is strongly asymmetric.

Theory of Liquid—Liquid Interface of Polymer Systems [PDF]

open access: yesPolymer Journal, 1976
Top of pageAbstract A theory for the interfacial tension and interface thickness of demixed polymer mixtures and polymer solutions is presented on the basis of the theory of Cahn and Hilliard, taking into account the change in the dimension of polymer coil at the interface.

Study of the dynamic formation of transmission gratings recorded in photopolymers and holographic polymer-dispersed liquid crystals [PDF]

open access: yes, 2004
Local and nonlocal models for the diffusion of photopolymers are applied to the dynamic formation of transmission gratings recorded in photopolymers and holographic polymer-dispersed liquid crystals (H-PDLCs). We retrieve the main parameters of H-PDLCs (

Light-activated modulation and coupling in integrated polymer-liquid crystal systems [PDF]

open access: yes, 2014
We explore the transfer of an incident light pattern onto the liquid crystal (LC) bulk in a photorefractive cell through an integrated photoconducting layer that modulates the electric field applied to the device.
