Block copolymers, including multiblock copolymers of an amphiphilic nature, because of their ability to form various supramolecular structures are attracting a lot of research interest these days. The direct influence on the supramolecular organization of block copolymers is a way of controlling both the mechanical and physicochemical properties of polymer materials obtained on this basis. *

In the article “Amphiphilic Poly(dimethylsiloxane-ethylene-propylene oxide)-polyisocyanurate Cross-Linked Block Copolymers in a Membrane Gas Separation” Ilsiya M. Davletbaeva, Ilgiz M. Dzhabbarov, Askhat M. Gumerov, Ilnaz I. Zaripov, Ruslan S. Davletbaev, Artem A. Atlaskin, Tatyana S. Sazanova and Ilya V. Vorotyntsev describe how they investigated Multiblock copolymers obtained based on PPEG, D4 (octamethylcyclotetrasiloxane ) and TDI ( 2,4-toluene diisocyanate ).*

The authors studied the realized polymers as membrane materials for the separation of gas mixtures containing CO2/CH4 and CO2/N2 and went on to show that polymers with a cellular supramolecular structure exhibit lower permeability for CO2 in comparison with polymeric film materials whose supramolecular structure is constructed on the basis of the “core-shell” principle. *

It was shown in the above mentioned article that polymers are promising as silica-based membrane materials for the separation of gas mixtures containing CO2/CH4 and CO2/N2. *

As the polymer material investigated for this article is rather soft NanoWorld Pointprobe® FMR AFM probes with a typical force constant of around 2.8 N/m were used for the analysis by atomic force microscopy of the membrane surface.*
