(Meth)acrylate liquid crystalline polymers for membrane applications
Original language description
Synthesis and characterization of a series of linear copolymers with liquid crystalline side chains is reported. Methacrylate monomers containing cyanobiphenyl as a mesogenic group were prepared. These monomers were then copolymerized with 2-ethylhexyl acrylate in varying molar ratios. The structure and composition of the monomers and corresponding polymers were determined by 1H-NMR, elemental analysis and size-exclusion chromatography. Thermal properties of the polymers were studied using differentialscanning calorimetry, polarized optical microscopy, and X-ray scattering techniques. Increasing mesogen content resulted in an increase of the glass transition temperature of the copolymers. Above a threshold mesogen content, the copolymers exhibited smectic mesophases. Using a solution casting technique, a membrane was fabricated to study single gas transport behaviors. Permeabilities were in the order of CO2?>?propylene?>?O2?>?N2?>?CH4?>?propane. Diffusion coefficients correlated well
