Morphology

In this work, the interaction, crystallization and morphology of membranes derived from polyamides/poly (vinylalcohol) (PA/PVA, PA: PA66, PA69, PA610 and PA612) blend materials are studied at various weight fractions and various crystallization temperatures. The experimental work includes differenti

A novel method for measuring local permeabilities of gas or vapor in polymers was proposed and developed. The method utilizes a thin reactive layer of potassium prepared on one side of the examined polymer film. Molecules of an appropriate gas (oxygen, water vapor) diffusing through the film corrode

HYFLON AD membranes are very interesting devices in water treatment and for their impermeability to water and gases and vapour transpirability [1]. In these kinds of processes, such in many large-scale processes, some membrane parameters are particularly important, among them: pore distribution, mem
