Abstract
Using biodegradable polymer, polylactide, two composites containing 5 wt % fillers, which are star-shaped macromolecules with a branching center, C60 fullerene, and grafted polymer arms of various nature, have been synthesized. The structural features and mechanical properties of the prepared film membranes were studied. The density and contact angles were determined to characterize the physical properties. The transport properties were studied by measuring the permeability of He, O2, N2, and CО2. It is shown that the incorporation of star-shaped modifiers into the polylactide matrix leads to a slight decrease in the permeability coefficients for all gases, but the ideal selectivity for O2/N2, Hе/N2, and CО2/N2 gas pairs increases.
期刊介绍：
The journal Membranes and Membrane Technologies publishes original research articles and reviews devoted to scientific research and technological advancements in the field of membranes and membrane technologies, including the following main topics:novel membrane materials and creation of highly efficient polymeric and inorganic membranes;hybrid membranes, nanocomposites, and nanostructured membranes;aqueous and nonaqueous filtration processes (micro-, ultra-, and nanofiltration; reverse osmosis);gas separation;electromembrane processes and fuel cells;membrane pervaporation and membrane distillation;membrane catalysis and membrane reactors;water desalination and wastewater treatment;hybrid membrane processes;membrane sensors;membrane extraction and membrane emulsification;mathematical simulation of porous structures and membrane separation processes;membrane characterization;membrane technologies in industry (energy, mineral extraction, pharmaceutics and medicine, chemistry and petroleum chemistry, food industry, and others);membranes and protection of environment (“green chemistry”).The journal has been published in Russian already for several years, English translations of the content used to be integrated in the journal Petroleum Chemistry. This journal is a split off with additional topics.
