Diffusion of solutes across poly(arylethersulfone) hollow fiber membrane

Diffusion of solutes across poly(arylethersulfone) hollow fiber membranes describes the passive transport of solute molecules (e.g., glucose, proteins, waste metabolites) across a synthetic polymer membrane composed of PAES such as polyethersulfone (PES)[2][6]. These membranes are engineered with microscopic pores and hydrophilic surfaces to enable separation, purification, and filtration in water treatment, biomedicine, and laboratory applications[2][3]. Solute movement is governed by concentration and pressure gradients, membrane pore size and structure, and physicochemical interactions between solute and membrane material[1][3]. PAES hollow fiber membranes are not receptors, enzymes, or transporters but are durable and biocompatible synthetic materials designed for high selectivity and permeance. Their performance is characterized by metrics such as flux, selectivity (molecular weight cut-off), porosity, mechanical strength, and resistance to fouling[2][6][3][4]. Applications include water purification, dialysis, biomolecule separation, and advanced filtration systems.
