Micro-and nanocomposite support structures for reverse osmosis thin film membranes

摘要

Disclosed are compaction resistant thin film composite membranes having a porouspolymeric support; a semi-permeable polymer film polymerized on the porouspolymeric support; and particles, of a size in the range of microparticles andnanoparticles, dispersed in the porous polymeric support. Also disclosed aremethods of making compaction resistant membranes by polymerizing a polymerfilm on a porous polymeric support with particles of a size in the range of microparticlesand nanoparticles dispersed therein, the particles having been selected toimprove flux flow characteristics over time of the semi -permeable membrane.Also disclosed are methods of purifying water using the disclosed membranes.This abstract is intended as a scanning tool for purposes of searching in the particularart and is not intended to be limiting of the present invention.
