Abstract
A-B-Type block copolymer (MSi) membranes consisting of poly (γ-methyl L-glutamate) (PMLG, A component) and poly (dimethylsiloxane) (PDMS, B component) were prepared, and their structure and gas transport properties were investigated. From the results of IR and X-ray diffraction measurements, it was confirmed that phase separation of α-helical PMLG and PDMS components has occurred in MSi membranes, and at the interface between the two phases, random-coil structure was induced in the PMLG component. The random-coil in MSi membrane increased with PDMS content. The solubility of CO2 for MSi membranes decreased with increasing the content of PDMS, because of the low-solubility of PDMS and the dense structure of random-coil phase. The CO2 permeability coefficient (P) of MSi membrane increased with PDMS content, although the value of P was smaller than that of PMLG membrane owing to the random-coil phase.
