Polymerization of pyrrole onto "track-etch" membranes

Poly(ethylene terephthalate) (PETP) "track-etch" membranes were used as a matrix For graft polymerization of pyrrole. Diaphragmatic method was utilized. Kinetics studies demonstrated a diffusion-limited behavior of pyrrole polymerization. Permeation properties of modified membranes were tested, New membrane material was prepared by decomposition of a matrix membrane, It comprises two support layers arranged one above the other forming a space between them for the flow of a first fluid. and a plurality of tubules joining two support layers, The flow of a second fluid can be organized through the microtubules. The membrane material characteristics calculated are close to that of natural biological systems. The possible method of mounting a filtration module based on the material is described.
