Study of Gases Permeation in Necklace-Shaped Dimethylsiloxane Polymers Bearing POSS Cages
The transport of small gases (H2, CO2, N2, O2) through a series of novel membranes based on necklace-shaped inorganic polymers (DMS@POSS), here in which a polyhedral oligomeric silsesquioxane (POSS) cage unit and soft chains of oligo-dimethyl siloxane (DMS) were alternately connected, was investigated.The influence of the DMS chain length and cross
