Evolution of polymeric hollow fibers as sustainable technologies: Past, present, and future
Na Peng,Natalia Widjojo,Panu Sukitpaneenit,May May Teoh,G. Glenn Lipscomb,Tai-Shung Chung,Juin-Yih Lai +6 more
TL;DR: In this article, the authors focus on state-of-the-art polymeric hollow fiber membranes made from non-solvent-induced phase inversion and the potential of membrane processes for sustainable water and energy production.

Evidence for spinodal decomposition and nucleation and growth mechanisms during membrane formation
TL;DR: In this paper, light scattering during immersion of cellulose acetate casting solutions in water / acetone coagulation baths was investigated by light scattering, and the morphology of membranes obtained by different mechanisms was compared.
Journal ArticleDOI
Formation of anisotropic membranes via thermally induced phase separation
TL;DR: The applicability of the thermally induced phase separation (TIPS) process to the production of anisotropic membranes was investigated in this article, where diluent was evaporated from one side of the polymer-diluent melt-blended, thereby creating a concentration gradient in the nascent membrane prior to inducing phase separation.

The effect of membrane formation parameters on performance of polyimide membranes for organic solvent nanofiltration (OSN): Part A. Effect of polymer/solvent/non-solvent system choice
TL;DR: In this paper, the importance of the choice of polyimide and solvent system was studied, and a simple tool based on mutual solubility parameters allowed to qualitatively predict the effect of polysimide choice and solvent composition used in dope solution on membrane performance.

Effect of evaporation step on macrovoid formation in wet-cast polymeric membranes
TL;DR: In this article, the effect of the initial casting solution concentration, film thickness, and duration of the evaporation step on the occurrence and prominence of macrovoid pores in cellulose acetate membranes cast from acetone solutions via the dry/wet phase-inversion process was investigated.

Transport properties of cellulose acetate osmotic membranes
TL;DR: In this article, the diffusion and distribution coefficients of water and sodium chloride have been measured in cellulose acetate osmotic membranes and a homogeneous diffusion model is proposed which describes the observations in terms of Fick's law.
