Abstract
New microstructurated copolymer membranes have been synthesized using a track-etched polycarbonate (PC) matrix. These membranes proved to be an important device in the field of ultra-filtration and synthetic membranes. These novel structures were obtained by irradiating at various angles (+30°, -30°). Such architecture is expected to improve not only the exchange properties but also, the behaviour under high flow pressure during their use as nanofiltration membranes. Membrane functionalization was performed with an amino acid as a simple biological model. Transmission and ATR-FTIR spectroscopies show that the doping state of copolymer dramatically influences the amino acid coupling rate. UV-vis spectroscopy indicates that the copolymer may be self-doped.
