in this research, modification on the ultrafiltration (uf) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (fo) water treatment. two monomers, m-phenylenediamine (mpd) and trimesoyl chloride (tmc) with different concentrations of mpd (2.0% w/v and 1.0% w/v) were reacted with tmc (0.15% w/v) for interfacial polymerization (...

The mesoporous polyamide (PA) aerogel similar in chemical structure to DuPont's Kevlar is an advanced thermal insulation material tested airspace applications. Unfortunately, the monolithic readily absorbs humidity (from moist air), which dramatically alters its mechanical properties. compressive strength of PA first increases when water content increases, but subsequently decreases following a...
