“…This IC strategy to prepare the CsPbX 3 PQDs/SEBS composite film was inspired by a water-casting method reported previously, [29][30][31] which has been reported widely for surface alignment/treatment, but scarcely for film fabrication despite its merits. [32][33][34] The polymer SEBS, with its unique triblock structure, offers excellent flexibility, stability, and adhesion.…”

Both dry‐ and wet‐process were employed for preparing membrane of ethylene‐vinylalcohol copolymer (EVAL) for blood dialysis. Asymmetric and symmetric, dense or porous membranes were prepared by the dry‐process. The relationship between the structure of membranes and the experimental variables is explained by using a solubility curve model. This model predicts the membrane structure successfully under various conditions, including the change of temperature of the environment, the solvent system and the temperature of polymer solution. For wet‐processes, the casting solutions were coagulated in a precipitation bath (water). Three different structures were obtained: finger type, sponge type and particle‐bonded type. The cloud point experiment and the polymer segment motion help to understand and control the membrane structure. Some properties of the EVAL membrane for blood dialysis are shown. It is comparable with or better than the commercialized one. This study may prove useful in determing the controlling parameters for the preparation of membranes from other polymers.

Preparation and catalytic action of an asymmetric ethylene/vinyl alcohol copolymer‐copper complex membrane

1992

An ethylene/vinyl alcohol copolymer (EVA)-copper complex membrane was prepared by casting an EVA-CuC1, mixture (solvent : water-propanol (1 : 1 v/v) mixture) on a polyethylene substrate and then immersing it in 0,l M KOH aqueous solution. In the membrane, Cu was distributed asymmetrically in the direction of the membrane cross section. The distribution of Cu could be controlled by the temperature during preparation. The oxidation of hydroquinone during permeation through the complex membrane was performed using membranes with different Cu distribution. This distribution influences the permeation reaction. These results are well reproduced by a relation composed of Fick's law and Michaelis-Menten type reaction kinetics. Therefore, a good reactor can be developed by controlling the catalyst distribution. 0 1992, Huthig & Wepf Verlag, Basel CCC 0025-1 16X/92/$05.00
