Various soluble polyimides with bis[4-(3-aminophenoxy)phenyl]sulfone and three kinds of dianhydrides were prepared in a polar N-methyl-2-pyrrolidone solvent by the traditional chemical two-step method. All the polymers synthesized had good solubilities in polar solvents and excellent thermal propert

A dye-binding procedure was developed for the analysis of protein attached to the membrane, with bound and adsorbed forms of attachment being distinguished. The relationship between modification procedure and protein attachment was explored and related to flux, streaming potential, and rejection wit
pH-sensitive poly(acrylic acid)-grafted membranes were prepared by an ultraviolet irradiation technique in air at room temperature. Peroxides produced on the membrane surface was quantified by 1,1-diphenyl-2-picrylhydrazyl (DPPH), which indicated that there existed an effective irradiation time for
Atomic force microscopy (AFM) and scanning tunnelling microscopy (STM) were used to investigate the surface of ultraΓltration membranes with pore sizes of ΒΏ10 nm. It is widely accepted that conventional AFM with TiO 2 or Si tips is not able to resolve pores in supported ceramic membranes with a dia
Surface-charge-mosaic-modified ultrafiltration membranes with charged domains of various sizes (500, 100, or 50 mm) were prepared by two-step laser-induced surface graft polymerization using a striped photomask. First, the surface of an ultrafiltration membrane was treated with 4-vinylpyridine after
The hindered diffusion of polystyrene in dilute solutions of ethyl acetate through polyimide ultrafiltration membranes has been investigated. The present system did not show specific membrane-solute interactions; furthermore, polystyrene can be considered as a flexible polymer coil. It is shown that
